Redraw Updates and Trends

Have you ever spent more than 20 minutes writing a detailed prompt, specifying lighting, texture, angle, style, materials, only to get back a generic result with no coherence to the actual project?

‍

That's the loop most architects fall into when they start using AI for renders. The “super prompt” promise is seductive: the more detail you describe, the better the AI understands. In practice, that's not what happens.

‍

Alexandre Kuhn, founder of Redraw, breaks down the technical reason behind this, and shows why the platform was designed to work in a completely different way.

‍

This article summarizes what is explained in depth in the video:

Why long prompts create more problems than they solve

Tools like ChatGPT Image and Nano Banana Pro (built on Gemini) work with a simple model: you describe, the AI generates. The more you detail, the more variables enter the process. It sounds logical, but that's exactly where the problem lives.

‍

Every AI image generation starts with what we call a “seed”: a random number that defines the starting point of the creative process. Two identical prompts with different seeds produce completely different images. In other words, you can spend an hour refining the perfect prompt and still get inconsistent results on every generation.

‍

The practical effect? Architects spend more time managing text than working on the project.

‍

‍

‍

How Redraw was designed to eliminate that frustration

Redraw starts from a different premise: architects shouldn't need to describe everything. The platform was built to understand the project context and deliver high-quality renders from direct, objective commands.

‍

A command like “render it realistically, indistinguishable from a real photo” is already enough to produce results other tools only deliver after multiple iterations and prompt tweaks.

‍

This isn't an accident, it's the result of a model trained specifically for architectural rendering, not a generic image generation model adapted to the task.

‍

What makes Redraw more efficient in practice:

• Smart lighting presets: instead of describing light in words, you choose from pre-defined options (golden morning, sunset, starry night) and apply with one click. Result: consistent and controlled on every generation.
• Direct element manipulation: add a fruit bowl, remove an object, adjust a texture, all done on the image itself, without rewriting the command from scratch.
• Processing speed: renders in under 30 seconds, enabling more iterations and faster decisions in your workflow.
• Short prompt, complete result: the model interprets architectural intent, not just typed words.

‍

‍

‍

Redraw, ChatGPT Image and Nano Banana: what each one delivers in practice

In the video, Alexandre tests the three tools side by side, with simple prompts and detailed prompts. The comparison reveals differences that go far beyond visual quality:

‍

ChatGPT Image 1.5: requires extensive prompts to deliver architectural coherence. With simple commands, results are generic and rarely ready for professional presentation.

‍

Nano Banana Pro (Gemini): performs well for general images, but inserts logos in some cases, a critical issue for professional use. Also depends on long descriptions for architecture-specific results.

‍

Redraw: superior results with short prompts, direct control over lighting and project elements, no watermarks or unwanted logos. Built for the architect's workflow, not for generic use.

‍

‍

The difference isn't just visual. It's operational: the time invested to reach a usable result in Redraw is significantly lower than in any other tool tested.

‍

‍

Redraw goes beyond rendering

Rendering is the entry point, but Redraw runs as a complete AI ecosystem for architecture:

• Idea Generator: explore facade, style and layout variations from a base image of the project.
• Render from sketch: turn a hand drawing or floor plan into a photorealistic image, no 3D model required.
• Brush (AI Brush): select a specific area of the image and modify only that region, texture, material, color, without altering the rest.
• Text to Image: generate visual references for presentations from a written description.
• Image to Video: turn a static render into an animation with depth and movement.

‍

All in a single platform. No switching between tools, exports and separate accounts.

‍

‍

Professional rendering doesn't have to be complicated

The complexity of super prompts is not a sign of sophistication, it's a sign that the tool wasn't built for your work.

‍

Redraw was made for architects, engineers and designers who need reliable, fast results with real control over the process. If you haven't tried it yet, access starts free.

Why diagrams and presentation boards make the difference

Concept diagrams and architectural presentation boards are the representations that show the reasoning behind the project, not just the outcome. They make the difference in competitions, juries, academic presentations, and high-level professional portfolios.

‍

With AI, you can generate concept diagrams, solar/ventilation analyses, urban diagrams, and even complete board layouts in minutes. The prompts in this guide cover all those cases with precision and control.

‍

‍

Before the prompts: why you don't need them in Redraw

Architects shouldn't need to learn machine language to generate professional representation. That premise guided how Redraw was built.

‍

Instead of writing warm late-afternoon natural light, long shadows entering from the side, in Redraw you click “Sunset”.

‍

Atmosphere & Mood in Redraw: lighting in one click, no long prompt.

‍

Instead of describing suburban residential street with visible neighbors in the background, you select the scene directly in the visual interface.

‍

Environment Selection in Redraw: scene in one click, no text description.

‍

Every choice you'd make in a long prompt, lighting, environment, style, camera, becomes a click. And because Redraw was trained exclusively for architecture, the model already “understands” the project context without you having to explain.

‍

“In Redraw, the less prompt users write, the better the results.”

‍

For diagrams and board layouts, the prompts in this guide remain the most efficient path, Redraw specializes in the photorealistic renders that go inside the board. The ideal combo: diagrams and boards with prompts + renders and perspectives with Redraw = complete presentation in minutes.

‍

‍

Comparison: text prompts vs. visual interface

‍

‍

PART 1, CONCEPT DIAGRAMS

‍

PROMPT 1, Automatic concept diagram generator

One of the most sophisticated prompts in the library. It instructs the AI to analyze the project's final massing and automatically derive a logical diagram sequence explaining how that form was generated.

‍

What it produces: a sequence of 5 to 7 isometric/axonometric diagrams showing the formal evolution of the project, from initial mass to subtractions, additions, and final configuration.

‍

When to use: Competition boards, jury presentations, portfolios with conceptual rigor. Concept diagrams are mandatory in any presentation that needs to explain why the project has the form it has.

‍

Prerequisite: have an image of the project's final 3D massing (can be a simple render, SketchUp, photographed physical model).

‍

The prompt:

Use the uploaded image strictly as the FINAL architectural massing reference. You must perform a geometric and spatial analysis of the final volumetry before generating any diagrams. Do NOT redesign, reinterpret, modify proportions, change geometry, adjust scale, or alter the architectural language of the final form. The final stage must be an EXACT volumetric match of the uploaded massing. STEP 1, MORPHOLOGICAL ANALYSIS (internal reasoning): Analyze the final massing and identify: Primary geometric primitive (rectangular block, L-shape, U-shape, courtyard block, fragmented bars, rotated volume, etc.) • Volumetric operations: Subtractions, Additions, Extrusions, Rotations, Offsets, Hierarchy, Fragmentation • Presence of: Setbacks, Internal voids, Courtyards, Overhangs, Directional elongation, Axial alignment. Derive a logical and architecturally coherent transformation sequence that plausibly generates the final form. All intermediate steps must geometrically and causally lead to the final configuration. STEP 2, GENERATE DIAGRAM SEQUENCE: Create 5 to 7 clean conceptual architectural diagrams explaining the formal evolution of the project. The sequence must include: Site + Initial Pure Mass • Solar Strategy • Ventilation Strategy • Volumetric Subtractions • Articulation / Fragmentation • Final Configuration. LANGUAGE REQUIREMENT (MANDATORY): All visible text inside the generated image MUST be written in Brazilian Portuguese. This includes: Titles, Subtitles, Diagram captions, Labels, Explanatory text, Step numbers descriptions. Do NOT use English in any visible graphic text. Use proper Brazilian architectural terminology (e.g., Implantação, Estratégia Solar, Ventilação Cruzada, Subtrações Volumétricas, Configuração Final, etc.). RULES: The final configuration must exactly match the uploaded volumetry. Do not invent architectural elements that are not present. Maintain proportional consistency between all stages. VISUAL STYLE: Isometric or axonometric projection • Pure diagrammatic style • No textures • No photorealism • Soft neutral pastel palette • Light background • Thin line weights • Minimal soft shadows only for volumetric clarity • Professional architectural competition board aesthetic • Balanced composition with white margins. GRAPHIC LANGUAGE: Sun path represented by a soft arc diagram • Wind shown with subtle curved directional arrows • Subtractions represented by dashed or transparent ghost volumes • Final massing in solid tone • Base platform indicating the site. OUTPUT REQUIREMENT: High resolution. Clean layout. Clear diagram hierarchy. Minimalist architectural presentation.

‍

What sets this prompt apart:

• The internal morphological analysis (Step 1) makes the AI reason about the project before generating, the result is logically coherent, not invented
• “All visible text MUST be written in Brazilian Portuguese”, result is immediately usable in boards with no text post-editing (swap the language to suit your locale)
• The visual hierarchy (ghost volumes for subtractions, solid for final configuration) is the standard language of international competition diagrams

‍

Result, Generated with Redraw

‍

‍

PROMPT 2, Solar and ventilation analysis

When to use: Complement to the concept diagram. Where Prompt 1 shows the formal evolution, this shows the environmental strategies that justify the formal decisions.

‍

The prompt:

Use the attached image as base reference. Create an architectural environmental analysis diagram based strictly on the provided volumetric model. Preserve 100% of the original architecture, geometry, proportions, openings, roof shape and perspective. Do NOT modify, redesign, reinterpret, simplify or alter any element of the project. The building must remain exactly as provided. Generate a clean conceptual diagram illustrating: Solar incidence (ensolação) • Sun path direction • Light exposure areas • Prevailing wind direction • Natural ventilation flow. Representation guidelines: Use soft translucent overlays to indicate sunlight • Use subtle warm gradient tones (yellow / orange) for solar impact • Use smooth curved arrows for wind flow (blue tones) • Maintain a minimal and elegant architectural diagram style • Keep a light neutral background • Do not exaggerate graphic elements • The architecture must remain the main focus. Text and labels must be written in Brazilian Portuguese only. Include labels such as: • Insolação • Ventos predominantes • Ventilação natural • Incidência solar • Norte. High-resolution architectural presentation quality. Clean, competition-level diagram aesthetic.

‍

What sets this prompt apart:

• Warm gradients (yellow/orange) for solar incidence, soft curved blue arrows for ventilation, the standard visual language of competition environmental diagrams
• “Do not exaggerate graphic elements”, prevents giant arrows and heavy overlays from visually dominating the diagram
• All labels in Portuguese (swap to your locale as needed), ready to use

‍

Result, Generated with Redraw

‍

‍

PROMPT 3, Conceptual urban diagram (full surroundings)

When to use: Projects in urban context where you need to show circulation flows, access points, green areas, and urban connections around the lot/block. Heavily used in site plan boards and urbanism projects.

‍

The prompt:

Use the uploaded image strictly as the base volumetric reference. The uploaded model contains only the white architectural massing. You must preserve 100% of the original building volumes, geometry, proportions, scale and perspective. Do NOT modify, redesign, reinterpret, subtract, add or distort the architectural masses in any way. The buildings must remain exactly as provided. OBJECTIVE: Transform the simple white volumetry into a complete conceptual urban architectural diagram. ADD THE FOLLOWING ELEMENTS: Urban Context: Surrounding streets around the block • Sidewalks • Street names (in Brazilian Portuguese) • Subtle lot demarcations • Clean urban grid indication. Central Landscape / Open Space: Organic pedestrian paths crossing the site • Green areas with soft shapes • Trees distributed naturally • Small plazas or gathering areas. Circulation and Flow Diagrams: Add conceptual arrows indicating: Pedestrian flow • Main access points • Secondary access • Urban connections • Possible vehicular flow. Use: Warm orange arrows for main flows • Thinner arrows for secondary paths • Soft shadows under arrows for depth • Slight transparency. Graphic Style: Architectural conceptual diagram aesthetic • White buildings (clean, no texture) • Soft pastel ground tones • Minimal color palette • Thin linework • Subtle shadows for depth • Light neutral background • Slight isometric or axonometric perspective • Professional competition board style. TEXT (MANDATORY: BRAZILIAN PORTUGUESE): Include subtle labels such as: Fluxo principal • Fluxo secundário • Acesso principal • Acesso de serviço • Área verde • Conexão urbana • Rua. IMPORTANT RULES: Architecture must remain the visual anchor. Do not exaggerate graphic elements. Vegetation must be simplified and diagrammatic. Maintain visual hierarchy.

‍

💡 How to adapt: The prompt uses the massing as a fixed reference. You can send a simple SketchUp model exported as an image, it doesn't need to be a final render.

‍

Result, Generated with Redraw

‍

‍

PROMPT 4, Conceptual site plan with frontal streets

When to use: Variation of the urban diagram for when the focus is the project's relationship with the front streets, corners, main accesses, connection with the frontal public space.

‍

The prompt:

Use the uploaded image strictly as the base volumetric reference. The uploaded image contains only the white architectural massing. You must preserve 100% of the original volumes, geometry, proportions, scale and perspective. Do NOT modify, redesign, reinterpret, subtract, add or distort any architectural element. The buildings must remain exactly as provided. OBJECTIVE: Transform the white volumetry into a clean conceptual urban diagram by adding only frontal street context and landscape organization. URBAN CONTEXT RULE, Very Important: Add streets ONLY in the FRONT portion of the composition. Create two perpendicular streets crossing in front of the site (forming a corner or cross intersection). Do NOT add any streets behind the buildings. The back portion must remain clean and minimal. The frontal streets must feel integrated and proportional to the building scale. ADD THE FOLLOWING ELEMENTS: Front Urban Streets: Two perpendicular streets crossing in front of the site • Sidewalks • Subtle curbs • Optional crosswalk markings (minimal) • Street names in Brazilian Portuguese. Central Landscape / Open Space: Organic pedestrian paths within the site • Trees in diagrammatic style • Soft green areas • Small plaza or gathering node if balanced. Circulation and Flow: Add conceptual arrows indicating: Fluxo principal • Fluxo secundário • Acesso principal • Conexão urbana. Use: Warm orange arrows for main flows • Thinner arrows for secondary flows • Soft drop shadows • Slight transparency. GRAPHIC STYLE: Architectural competition diagram aesthetic • White massing volumes (no texture) • Soft pastel ground tones • Thin linework • Minimal color palette • Light neutral background • Slight axonometric or isometric perspective. TEXT (MANDATORY: BRAZILIAN PORTUGUESE): Include: Fluxo principal • Fluxo secundário • Acesso principal • Área verde • Rua • Conexão urbana. Modern, clean sans-serif typography.

‍

Difference from Prompt 3: while the full urban diagram shows the entire block context, this one focuses only on the frontal relationship, cleaner and more direct for projects where the main access is the most relevant element of the site plan.

PART 2, ARCHITECTURAL BOARDS

‍

PROMPT 5, A1 vertical board (Style 01)

When to use: Competition or portfolio boards with clean layout and clear hierarchy, main render on top, plans and sections in the middle, sections at the base.

‍

What it generates: complete A1 vertical board layout with typographic hierarchy, organized grid, and a neutral/warm tonal palette.

‍

How to use: send the project images along with the prompt. The AI will compose the layout using the provided elements.

‍

The prompt:

Tips for using the board prompts

Send elements separately: The AI composes better when it receives renders, plans, and sections as separate images that it organizes into the layout, instead of trying to extract elements from a composite image.

‍

Specify the project name: Add to the prompt: “Project name: [project name]. Subtitle: [type/location].”

‍

Custom palette: If your project has a defined visual identity, add: “Use [color] as the primary accent color throughout the board.”

‍

Output format: The AI will generate an image of the layout. For later editing in Illustrator or InDesign, you can use the image as a composition reference and recreate the layout with the original files.

‍

‍

AI change control system

Use these complementary prompts when the AI alters elements that it shouldn't in your diagrams or boards.

‍

Total change lock

Preserve 100% of the original architecture, layout, furniture placement, materials, colors, textures, decorative elements, proportions, lighting positions, and camera angle. Strictly forbid adding, removing, replacing, resizing, repositioning, or redesigning any element. The purpose of this transformation is ONLY to enhance realism, lighting behavior, and material response without altering the original design in any way.

‍

‍

Lighting design respect

Preserve the original lighting design exactly as shown in the image. Do not add new light sources, remove existing lights, or modify lighting positions. Only enhance realism through natural light diffusion, realistic light bounce, soft shadow transitions, and accurate material interaction with existing lighting.

‍

‍

Material protection

Preserve all original materials and textures exactly as shown. Do not replace, reinterpret, or stylize materials. Enhance realism only through improved surface detailing, micro imperfections, and physically accurate light response.

‍

‍

Enhance natural lighting without altering the project

Use the uploaded image strictly as the ONLY architectural reference. The architecture and scene composition are completely locked. Preserve 100% of the original: Architecture • Walls and openings • Furniture placement • Materials and colors • Textures • Layout and proportions. Enhance the scene by making natural daylight more predominant and realistic. The project must remain 100% identical to the original image. Only the lighting quality and natural daylight intensity may be improved. Ultra realistic architectural photography, high dynamic range, 8K detail.

‍

‍

Which AI to use for diagrams and boards?

For concept diagrams, environmental analyses, and board layouts, text-based AI image generation tools with the prompts in this guide are the most efficient workflow available, the AI reads the massing and generates the diagram in minutes.

‍

For the renders inside the board, exterior perspectives, interior renders, facades, Redraw is the most direct and project-faithful tool. You don't need long prompts: upload the model (SketchUp, Archicad, Revit, Rhino, 3DS), pick the style and environment in clicks, and the render comes out in 20 to 40 seconds.

Why humanized floor plans sell projects

The humanized floor plan is one of the most requested representations in residential presentations, portfolios, and real estate sales materials. It transforms the technical plan, full of dimensions, hatching, and symbols, into a visualization that lay clients can understand and imagine inhabiting.

‍

With AI, you can humanize a plan in seconds. But the challenge is always the same: the AI cannot alter the layout, move walls, resize rooms, or change the original plan in any way. The prompts in this guide were developed with that central premise.

‍

Practical heads-up: before processing any plan with AI, export it clean, no dimensions, no legend texts, no heavy hatching. The prompt already instructs the AI to ignore texts and annotations, but the cleaner the input, the more accurate the result. To skip this step entirely, Redraw processes the 3D model directly.

‍

‍

Before the prompts: why you don't need them in Redraw

Architects shouldn't need to learn machine language to generate professional representation. That premise guided how Redraw was built.

‍

Instead of writing warm late-afternoon natural light, long shadows entering from the side, in Redraw you click “Sunset”.

‍

Atmosphere & Mood in Redraw: lighting in one click, no long prompt.

Before, technical plan exported from software

‍

‍

PROMPT 1, Ultra realistic

When to use: High-end presentations, real estate sales materials, portfolios where the client wants to see the plan with real material textures, wood, fabric, ceramic, rug.

‍

Visual style: Orthographic top view, photorealistic materials, subtle depth shadows, simulated natural lighting.

‍

The prompt:

Transform this architectural floor plan into a highly realistic humanized floor plan. Preserve 100% of the original layout, wall positions, openings, structure thickness, furniture placement, circulation areas, proportions and dimensions. Do NOT redesign, reinterpret, move, resize or modify any architectural element. Do NOT change the scale. Ignore all texts, annotations and dimension numbers. Focus only on the architectural geometry. Apply realistic top-view materials and textures: Natural wood flooring with subtle grain variation • Soft fabric texture on bed and sofa with visible folds • Realistic bedding layers and pillows with natural volume • Matte painted walls with slight tonal variation • Subtle shadowing under furniture for depth • Realistic rugs with soft texture • Desk surface with light reflection and material response • Accurate perspective strictly in orthographic top view (no camera distortion). Lighting: Soft ambient daylight simulation • Gentle global illumination • Soft contact shadows • Subtle depth separation between spaces. Enhance realism with micro-details: Slight fabric wrinkles • Wood grain variation • Soft shadow gradients • Minimal surface imperfections • Natural color balance. Style: Professional architectural presentation • High-end real estate humanized floor plan • Clean, elegant and realistic • Ultra high resolution • Balanced color grading • Sharp but natural finish. Maintain strict architectural accuracy and original proportions.

‍

What sets this prompt apart:

• Ignore all texts, annotations and dimension numbers, essential instruction so you don't get distorted dimension lines in the final image
• Accurate perspective strictly in orthographic top view (no camera distortion), prevents the AI from adding unwanted isometric perspective
• Soft contact shadows, what creates realistic depth without looking like a 3D render

‍

PROMPT 2, Soft clean editorial

When to use: Presentation boards with Scandinavian/Japandi aesthetics, modern portfolios, mid-to-high-end real estate sales materials. It's the “Pinterest plan” style, the most visually shareable.

‍

Visual style: Neutral desaturated palette, light wood, beige fabrics, almost imperceptible shadows, airy and clear feeling.

‍

The prompt:

Transform this architectural floor plan into a soft, clean and refined humanized floor plan visualization. Preserve 100% of the original layout, walls, openings, structure thickness, furniture placement, circulation areas, proportions and dimensions. Do NOT redesign, reinterpret, move, resize or modify any architectural element. Do NOT change scale. Maintain strict orthographic top view (no perspective distortion). Ignore all texts, labels and dimension numbers. Focus only on architectural geometry. VISUAL STYLE: Create a light, neutral and calm presentation style, similar to modern editorial architectural boards. Avoid dramatic realism. Avoid strong shadows. Avoid high contrast. Avoid overly saturated wood tones. MATERIAL APPLICATION: Light natural oak wood flooring with very subtle grain • Neutral beige fabric upholstery • Soft linen bedding with delicate folds • Low-contrast rugs with minimal pattern • Matte off-white painted walls • Light natural wood furniture with minimal texture contrast • Soft ceramic surfaces in bathrooms • Minimal reflections. LIGHTING: Diffused ambient daylight • Very soft contact shadows • Subtle depth separation • No dramatic directional light • Balanced exposure • Clean brightness. The lighting should feel airy and evenly distributed. FINAL MOOD: Scandinavian-inspired softness • Pinterest-style clean floor plan • Calm neutral palette • Elegant and minimal • High resolution • Refined but not hyper-realistic. Maintain architectural precision and original proportions at all times.

‍

The final mood instruction, “Scandinavian-inspired softness • Pinterest-style clean floor plan”, communicates a cohesive aesthetic reference to the AI that results in a very specific and commercially efficient palette.

‍

PROMPT 3, Graphic monochromatic

When to use: Competition boards, academic presentations, portfolios with strong visual identity where black and white is an intentional aesthetic choice.

‍

Visual style: Solid black walls, white/light grey furniture, floor with optional subtle herringbone or flat grey, delicate shadows.

‍

The prompt:

Transform this architectural floor plan into a refined monochromatic humanized floor plan with strong graphic contrast. Preserve 100% of the original layout, wall thickness, openings, structure, furniture placement, circulation areas, proportions and scale. Do NOT redesign, reinterpret, move, resize or modify any architectural element. Maintain strict orthographic top view (no perspective distortion). Ignore all texts, annotations and dimension numbers. Focus only on architectural geometry. WALL TREATMENT: Render all structural walls in solid matte black or very dark charcoal • Maintain accurate wall thickness • Clean crisp edges • No texture on walls (flat graphic fill).

PROMPT 6, External landscaping (humanized plan)

When to use: You've already humanized the plan internally (with prompts 1–4) and now want to add the landscaping context around it, without the AI reinterpreting the interior.

‍

The prompt:

Use the uploaded image as a FINAL, FLATTENED architectural board. This image is already finished and humanized. You must treat the floor plan as a locked image layer. DO NOT redraw. DO NOT reinterpret. DO NOT convert to black and white. DO NOT restyle. DO NOT enhance. DO NOT relight. DO NOT change materials. DO NOT change shadows. DO NOT adjust colors. DO NOT increase or reduce contrast. DO NOT modify texture. DO NOT modify saturation. The floor plan must remain PIXEL-PERFECT identical to the uploaded image. No internal changes are allowed. OBJECTIVE: Add soft natural vegetation context ONLY around the external perimeter of the existing image. This is an additive background operation only. WHAT YOU CAN ADD (OUTSIDE ONLY): Soft green watercolor ground texture • Light grass tonal variation (olive, sage, muted green) • Semi-transparent tree canopies (top view) • Soft organic tree shadows • Slight edge fading into white background • Subtle natural landscape blending. STRICT LIMITATIONS: Do NOT overlap the building footprint • Do NOT cover walls, furniture or internal patios • Do NOT modify linework • Do NOT modify rendering style • Do NOT change perspective • Do NOT touch the interior. STYLE: Soft architectural presentation style • Competition board aesthetic • Subtle, elegant, low saturation • Top-view orthographic • Natural daylight tone.

‍

The AI tends to “improve” the image when it doesn't get clear restrictions, reprocesses colors, increases contrast, changes materials. The capped “DO NOT” instructions block each of these unwanted behaviors.

‍

‍

AI change control system

Use these complementary prompts when the AI is moving walls, swapping materials, or altering the original plan.

‍

Total change lock

Preserve 100% of the original architecture, layout, furniture placement, materials, colors, textures, decorative elements, proportions, lighting positions, and camera angle. Strictly forbid adding, removing, replacing, resizing, repositioning, or redesigning any element. The purpose of this transformation is ONLY to enhance realism, lighting behavior, and material response without altering the original design in any way.

‍

‍

Lighting design respect

Preserve the original lighting design exactly as shown in the image. Do not add new light sources, remove existing lights, or modify lighting positions. Only enhance realism through natural light diffusion, realistic light bounce, soft shadow transitions, and accurate material interaction with existing lighting.

‍

‍

Material protection

Preserve all original materials and textures exactly as shown. Do not replace, reinterpret, or stylize materials. Enhance realism only through improved surface detailing, micro imperfections, and physically accurate light response.

‍

‍

Why humanized sections still win on architecture boards

The humanized section is one of the most valued representations in competition boards, academic presentations, and professional portfolios. It transforms a technical drawing into an illustration that communicates atmosphere, human scale, materiality, and design intent, without needing photorealism.

‍

With AI, you can generate high-quality humanized sections in seconds. The challenge is keeping the original geometry intact while the AI applies the desired style. The prompts in this guide were developed exactly for that.

‍

Important: These prompts are for text-based AI image generation tools, applied to the section drawing exported from your software. For photorealistic interior and facade renders, Redraw offers a more direct path, but for stylized sections, text prompts are the most efficient workflow today.

‍

‍

Before the prompts: why you don't need them in Redraw

Architects shouldn't need to learn machine language to generate professional representation. That premise guided how Redraw was built.

‍

Instead of writing warm late-afternoon natural light, long shadows entering from the side, in Redraw you click “Sunset”.

‍

Atmosphere & Mood in Redraw: lighting in one click, no long prompt.

‍

Instead of describing suburban residential street with visible neighbors in the background, you select the scene directly in the visual interface.

‍

Environment Selection in Redraw: scene in one click, no text description.

‍

Every choice you'd make in a long prompt, lighting, environment, style, camera, becomes a click. And because Redraw was trained exclusively for architecture, the model already “understands” the project context without you having to explain.

‍

“In Redraw, the less prompt users write, the better the results.”

‍

For stylized humanized sections, the prompts in this guide remain the most efficient path, Redraw specializes in photorealistic interior and facade renders. The ideal combo: humanized sections with prompts + photorealistic renders with Redraw = complete board in minutes.

‍

‍

Comparison: text prompts vs. visual interface

‍

‍

PROMPT 1, Graphic / editorial style

When to use: Competition boards, university presentations, professional portfolios where you want a modern, clean representation with strong visual identity.

‍

Visual style: Limited palette, flat fills, graphic human silhouettes, simplified vegetation, neutral background.

‍

The prompt:

Transform this architectural section drawing into a stylized humanized architectural illustration. Preserve 100% of the original geometry, proportions, walls, slabs, structure, openings and composition. Do NOT change or redesign any architectural element. Do NOT make it photorealistic. Apply a soft graphic representation style with: Flat color fills • Controlled limited color palette (monochromatic or earthy tones) • Light texture overlays • Soft shading instead of realistic shadows • Subtle depth separation between foreground and background • Simplified vegetation silhouettes • Minimal human silhouettes in a graphic style • Clean white or neutral background. Keep linework clean and architectural. Maintain section clarity and readability. Style reference: Architectural competition board illustration, Pinterest architectural section style, soft editorial graphic visualization. High resolution, elegant, minimal, refined presentation.

‍

What makes this prompt effective:

• Flat color fills, avoids heavy gradients that clutter the section
• Controlled limited color palette, keeps visual cohesion on the board
• Minimal human silhouettes in a graphic style, human figures as scale reference, not realistic elements
• Maintain section clarity and readability, the AI cannot compromise the technical reading of the section

‍

💡 Tip: If you want to specify a color palette, add: “Use [main color] as the primary accent color throughout the illustration.”

‍

‍

PROMPT 2, Soft watercolor

When to use: Projects where you want to convey delicacy, humanity, and creative process. Very effective for residential, cultural, and educational architecture. Works very well on boards with white or kraft paper background.

‍

Visual style: Hand-painted watercolor textures, muted natural palette, painted vegetation, subtle human figures, soft atmospheric depth.

‍

The prompt:

Transform this architectural section drawing into a soft watercolor-style architectural illustration. Preserve 100% of the original geometry, structure, walls, slabs, openings, proportions and composition. Do NOT modify or redesign any architectural element. Avoid photorealism. Avoid 3D render appearance. Avoid strong contrast or dramatic lighting. Apply a delicate watercolor illustration style with: • Soft hand-painted textures • Light paper grain background • Muted natural color palette (warm beige, soft green, light brick, pale wood) • Subtle tonal variation instead of realistic shading • Very soft shadow indication • Gentle atmospheric depth • Light vegetation painted in watercolor style • Minimal human figures illustrated softly • Clean and calm architectural presentation. Keep the section readable and elegant. Architectural competition board style, artistic, refined, minimal, soft and atmospheric. High resolution, delicate textures, subtle detail, calm neutral mood.

‍

What makes this prompt effective:

• Avoid strong contrast or dramatic lighting, soft watercolor doesn't have aggressive contrast
• Light paper grain background, simulates real watercolor paper
• Muted natural color palette, the specific palette guides the AI to tones that work together

‍

Result, Generated with Redraw

‍

‍

PROMPT 3, Green monochromatic

When to use: When you want a strong and cohesive visual identity on the board, using a single color as accent. Green is the default color of this prompt, but it can be adapted.

‍

Visual style: Neutral base (beige/off-white), sage/forest green accents only on structural elements (slab cuts, columns, frames), vegetation in desaturated greens, paper-textured background.

‍

The prompt:

Transform this architectural section drawing into a refined graphic architectural illustration. Preserve 100% of the original geometry, structure, walls, slabs, openings, proportions and composition. Do NOT redesign or modify any architectural element. Avoid photorealism. Avoid 3D rendering. Keep it flat and graphic. Color treatment: Use a soft warm beige or light off-white tone for interior surfaces • Keep floors, walls and ceilings in light neutral tones • Apply muted sage or forest green ONLY to structural outlines, slab edges, columns and section cuts • Keep window frames and structural grid lines in green • Do NOT fill the entire building with green. Visual style: Light paper texture background • Soft subtle shadow indication (not realistic) • Clean linework • Minimal tonal variation • Graphic architectural competition board style. Add: Human silhouettes in muted green tone • Soft vegetation in desaturated green tones • Very light sky with subtle cloud shapes. Balanced composition, elegant, minimal and refined presentation. High resolution, calm architectural board aesthetic.

‍

In architectural sections, highlighting only what is being cut (not the entire space) is the correct technical rule. The AI needs to receive this instruction explicitly.

PROMPT 4, Universal with custom color

This is the most versatile prompt in the section library. It uses color placeholders you replace before sending, letting you create any visual identity without rewriting the prompt from scratch.

‍

How to use: replace [PRIMARY COLOR] and [INTERIOR COLOR] with your choice before sending.

‍

Combination examples:

• [PRIMARY COLOR] → muted sage green | [INTERIOR COLOR] → warm beige
• [PRIMARY COLOR] → terracotta red | [INTERIOR COLOR] → light sand
• [PRIMARY COLOR] → deep navy blue | [INTERIOR COLOR] → soft ivory
• [PRIMARY COLOR] → dusty rose | [INTERIOR COLOR] → off-white

‍

The prompt:

Transform this architectural section drawing into a refined graphic architectural illustration. Preserve 100% of the original geometry, structure, walls, slabs, openings, proportions and composition. Do NOT redesign, reinterpret, move or modify any architectural element. Avoid photorealism. Avoid 3D rendering. Keep it flat and graphic. Color treatment: Use [PRIMARY COLOR] ONLY for structural outlines, slab edges, columns, section cuts and window frames. • Use [INTERIOR COLOR – usually beige, off-white or light neutral] for interior walls, floors and ceilings. • Do NOT fill the entire building with [PRIMARY COLOR]. • Interior spaces must remain predominantly [INTERIOR COLOR]. Visual style: Light paper texture background • Clean architectural linework • Minimal tonal variation • Soft subtle shadow indication (not realistic lighting) • Graphic architectural competition board style. Add: Human silhouettes in [PRIMARY COLOR] • Vegetation in softer desaturated tones of [PRIMARY COLOR] • Very light neutral sky with subtle cloud shapes. Balanced composition, elegant, minimal and refined presentation. High resolution, calm architectural board aesthetic.

‍

You build the visual identity of an entire board with a two-word substitution. Visual consistency between all sections of the same project becomes trivial.

Tips for humanized sections with AI

• Export the section in high resolution: the result quality depends on the input quality. At least 150 dpi, preferably 300 dpi.
• Black lines, white background: make sure the section has clean and readable lines on white background before sending.
• Simple sections work better: the cleaner the input, the more predictable the result. If the section has many details, simplify first.
• Combine prompts: use the style + Total Lock prompt if the AI is altering geometry.

Why facade renders are AI's decisive test

The facade is the project's calling card. It's the first thing the client sees, what appears on the portfolio cover, and what circulates on social media. A convincing facade render depends on two factors most architects neglect: realistic urban context and correct light condition.

‍

Generic AI tools tend to “invent” the surroundings, change the original facade, or produce inconsistent results between generations. The prompts in this guide were designed to solve exactly that, each one preserves 100% of the original facade while working only on what needs to be improved.

‍

About Redraw: For facade renders with project fidelity, Redraw is the most direct tool, you upload the model, select the atmosphere in clicks, and get the result in seconds, with no risk of the AI altering the facade. The prompts below are for those working with text-based generation tools.

‍

‍

Before the prompts: why you don't need them in Redraw

Architects shouldn't need to learn machine language to generate a professional facade render. That premise guided how Redraw was built.

‍

‍

Comparison: text prompts vs. visual interface

‍

The prompts in this guide remain valuable, understanding the logic makes you a more strategic user of any tool. But if you want to skip the learning curve and go straight to the result, Redraw solves it in clicks.

‍

‍

PROMPT 1, Adding urban context: neighboring houses

Problem it solves: Facades rendered against white or generic backgrounds don't convey the project's real urban context. Clients and developers need to see how the project fits into the street.

‍

When to use: Residences on urban lots where neighborhood context is relevant for the presentation.

‍

The prompt:

Transform this image into an ultra photorealistic architectural photograph. Preserve 100% of the original architecture, layout, furniture placement, materials, colors, textures, proportions, decorative elements, and camera angle. Do NOT add, remove, redesign, or replace any element of the main project. Enhance realism only through: Physically accurate global illumination • Natural light behavior and realistic light bounce • Soft and natural shadow gradients • Ray traced reflections and refractions • Real-world material response. Add neighboring houses on both sides of the main construction, integrating them naturally into the urban context. The neighboring houses must: • Respect correct scale and perspective • Follow realistic residential architectural language • Maintain coherent lighting direction • Not block or interfere with the visibility of the main project • Not cast unrealistic shadows over the main façade • Remain secondary elements in the composition. Under no circumstances modify, adjust, reinterpret, resize, or redesign the original main building. Professional architectural photography style, balanced HDR exposure, natural color grading, cinematic yet realistic atmosphere. Ultra high resolution, 8K detail.

‍

What sets this prompt apart: The detailed instruction on how neighboring houses should behave, scale, perspective, light direction, and visual hierarchy. Without it, the AI may produce neighbors that visually compete with the project or distort perspective.

PROMPT 2, Adding natural context: trees

Problem it solves: Facades without vegetation feel cold and decontextualized. Adding trees increases realism and elevates the project, as long as it's done with control over scale and shadows.

‍

When to use: Any type of facade, residential, commercial, mixed-use, where natural vegetation improves the presentation.

‍

The prompt:

Transform this image into an ultra photorealistic architectural photograph. Preserve 100% of the original architecture, layout, furniture placement, materials, colors, textures, proportions, decorative elements, and camera angle. Do NOT add, remove, redesign, or replace any element of the main project. Enhance realism only through: Physically accurate global illumination • Natural light behavior and realistic light bounce • Soft and natural shadow gradients • Ray traced reflections and refractions • Real-world material response. Add realistic trees around the main construction, integrating them naturally into the surrounding context. The trees must: • Respect correct scale and perspective relative to the building • Be positioned naturally (side areas, background, or sidewalk alignment) • Maintain coherent lighting direction and shadow behavior • Cast physically accurate and soft shadows • Not block or interfere with the visibility of the main façade • Remain secondary elements in the composition • Appear as natural landscape additions, not decorative overlays. Under no circumstances modify, adjust, reinterpret, resize, or redesign the original main building. Professional architectural photography style, balanced HDR exposure, natural color grading, cinematic yet realistic atmosphere. Ultra high resolution, 8K detail.

‍

If you want a specific type of tree (palms, oaks, cedars), add to the prompt: “Use [tree type] as the primary vegetation species.”

PROMPT 3, Post-rain atmosphere (ultra realistic)

Problem it solves: Post-rain facades with wet floor reflections and surface moisture are among the most visually impactful renders, and among the hardest to do with control. This prompt solves it.

‍

When to use: High-impact presentations, portfolios, social media. Works especially well on facades with concrete, stone, paving, and metal.

‍

The prompt:

Preserve 100% of the original architecture, materials, colors, textures, proportions, decorative elements, lighting fixtures, surrounding elements, landscaping, and camera angle. Do NOT add, remove, redesign, reposition, replace, or reinterpret any element. Transform the image into an ultra photorealistic architectural photograph representing a natural post-rain environment. Simulate realistic wet surface conditions on ground planes, pavements, streets, and exposed exterior surfaces, ensuring physically accurate water reflection behavior and subtle moisture accumulation. Enhance reflective properties on materials such as stone, concrete, glass, metal, and flooring through realistic surface roughness variation, water film reflections, and natural light diffusion across wet areas. Introduce subtle environmental dampness indicators such as slightly darkened material tones, enhanced reflection clarity, and realistic interaction between moisture and lighting. Maintain balanced HDR exposure, natural color grading, realistic sky brightness consistency, soft shadow transitions, and accurate global illumination under post-rain atmospheric conditions. Ensure reflections remain physically plausible and proportional, avoiding exaggerated mirror effects while preserving realistic depth and material response. Professional architectural photography quality, cinematic yet natural atmosphere, ultra high resolution, 8K detail, and full-frame camera realism.

‍

What sets this prompt apart: The instruction “avoiding exaggerated mirror effects” is fundamental. Without it, the AI tends to create floor mirror reflections that look unreal.

PROMPT 4, Universal daytime atmosphere

Problem it solves: The most versatile facade prompt, transforms any facade render into a daytime architectural photograph with realistic natural light.

‍

When to use: Starting point for any facade when you want a clean and professional photorealistic result, without defining a specific atmosphere.

‍

The prompt:

Preserve 100% of the original architecture, materials, colors, textures, proportions, decorative elements, lighting fixtures, surrounding elements, landscaping, and camera angle. Do NOT add, remove, redesign, reposition, replace, or reinterpret any element. Transform the image into an ultra photorealistic daytime architectural photograph. Enhance realism through physically accurate daylight simulation, natural sky illumination, realistic sun direction, soft shadow gradients, global illumination, and accurate environmental light bounce. Improve facade material response with micro surface imperfections, subtle tonal variation, realistic roughness maps, natural reflection behavior on glass and metal, and authentic surface depth. Maintain balanced HDR exposure, natural color grading, realistic atmospheric clarity, professional full-frame camera behavior, subtle depth perception, and true-to-life sharpness. Ultra high resolution, 8K detail, cinematic yet realistic architectural photography quality.

‍

‍

Result with Nano Banana Pro

‍

‍

PROMPT 5, Overcast (ultra realistic)

Problem it solves: Overcast light is the favorite of professional architectural photographers, it's diffused, casts no harsh shadows, and reveals the real material texture. This prompt replicates that effect.

‍

When to use: Facades with textured materials (exposed concrete, brick, stone) where you want texture to be the protagonist. Also works very well on dark facades or low-reflection materials.

‍

The prompt:

Preserve 100% of the original architecture, materials, colors, textures, proportions, decorative elements, lighting fixtures, surrounding elements, landscaping, and camera angle. Do NOT add, remove, redesign, reposition, replace, or reinterpret any element. Transform the image into an ultra photorealistic architectural photograph under overcast sky conditions. Simulate diffused environmental lighting with soft, evenly distributed illumination across all facade surfaces. Reduce harsh shadow contrast while maintaining realistic depth perception, natural material response, accurate environmental reflections, and subtle tonal transitions. Enhance facade texture clarity with physically accurate surface roughness, micro imperfections, realistic light absorption, and natural color consistency under cloudy lighting conditions. Maintain professional architectural photography standards, balanced exposure, realistic atmospheric depth, and ultra high resolution 8K detail.

‍

What sets this prompt apart: “Reduce harsh shadow contrast” is the key to overcast days. Soft shadows and uniform diffused light are exactly what differentiate a professional facade photograph from a hard-sun render.

‍

‍

PROMPT 6, Night (ultra realistic)

Problem it solves: Night renders are hard to do well, the balance between the project's artificial lighting and the dark environment is the great challenge.

‍

When to use: Projects with elaborate artificial lighting, commercial, high-end residential, restaurants, hotels. Night renders are often the most impactful for these.

‍

The prompt:

Preserve 100% of the original architecture, materials, colors, textures, proportions, decorative elements, lighting fixtures, surrounding elements, landscaping, and camera angle. Do NOT add, remove, redesign, reposition, replace, or reinterpret any element. Transform the image into an ultra photorealistic nighttime architectural photograph. Simulate realistic night environmental conditions with accurate low-light exposure, natural darkness balance, and physically correct interaction between existing artificial lighting and surrounding shadows. Enhance realistic light falloff, warm and cool contrast balance, subtle reflections on glass surfaces, accurate ambient occlusion, soft shadow transitions, and volumetric light interaction where appropriate. Refine facade materials with realistic surface depth, micro imperfections, subtle reflection roughness variation, and true-to-life night photography exposure control. Professional architectural night photography style, balanced dynamic range, cinematic yet natural atmosphere, ultra high resolution, 8K detail.

‍

What sets this prompt apart: “warm and cool contrast balance” and “light falloff” are the two parameters that make a night render look like a real photo. Warm light from fixtures vs. cool blue of the night ambient.

‍

‍

Result with Nano Banana Pro

‍

‍

PROMPT 7, Blue hour (premium transition)

Problem it solves: Blue hour, that moment between end of day and full night, is the most sought-after timing in professional architectural photography. Ambient light still exists, but the project's artificial lights are already on. The contrast is cinematic.

‍

When to use: Portfolios, high-impact presentations, projects with significant artificial lighting. It's the hardest render to do manually and one of the most efficient with AI.

‍

The prompt:

Preserve 100% of the original architecture, materials, colors, textures, proportions, decorative elements, lighting fixtures, surrounding elements, landscaping, and camera angle. Do NOT alter any architectural or design element. Transform the scene into an ultra photorealistic blue hour architectural photograph. Balance residual ambient daylight with existing artificial lighting, creating realistic contrast between cool environmental tones and warm interior illumination. Enhance subtle reflections, soft shadow layering, atmospheric depth, physically accurate light diffusion, and realistic material response. Maintain cinematic yet natural color grading, professional camera exposure control, realistic dynamic range, and ultra high resolution 8K architectural photography quality.

‍

What sets this prompt apart: “balance residual ambient daylight with existing artificial lighting”, this instruction is what creates the real blue hour contrast. Without it, the AI tends to go straight to night or day, with no transition.
