Tips for Interior Living

  • Specify room type and function — open-plan living room, primary bedroom
  • Call out key materials (polished concrete, oak, terracotta) and furniture style
  • Describe lighting condition and time of day
  • Add one person or figure for scale unless you want a purely empty showroom look

Language as Design Language

Why Prompts Matter for AI Architectural Rendering

Modern AI rendering — including Nano Banana Pro — interprets language as a design language. It infers materials, lighting, scale, and atmosphere from your prompt instead of only from geometry.

A generic prompt like "modern house" yields generic results. A structured prompt communicates architectural style, materials, lighting and time of day, spatial context, and photographic style — together.

The templates in this library are tuned for photorealistic architectural visualization, competition boards, and client-ready imagery. They work across sketch-to-render, reference-image, and text-to-image workflows.

01

Generic vs. Structured

"Modern house" yields generic results. "Contemporary open-plan living room, polished concrete, floor-to-ceiling glazing, warm afternoon light, 16:9" yields a client-ready render.

02

Geometry + Prompt = Control

Upload your sketch to define composition and massing. The prompt handles materials, light, and atmosphere. Together you get precise results on the first generation.

03

Iterative Refinement

Create variations by exploring small language tweaks (Brutalist instead of modern), add specific materials (Corten steel cladding), adjust lighting (switch to night with dramatic uplighting) until you match design intent.

Creative-Quality Model

How Prompts Work with Nano Banana Pro

Nano Banana Pro is a studio-grade AI rendering model with deep design intelligence and style control. Unlike generic image generators, it understands:

  • Spatial language: aerial view, street-level, axonometric
  • Materials: Corten steel, exposed concrete, polished plaster
  • Lighting: golden hour, overcast diffused, moonlit

For best results: combine your sketch or reference image (geometry and massing) with a well-structured prompt (materials, light, atmosphere) and the correct aspect ratio.

Prompt Engineering

Advanced AI Rendering Prompting Techniques

Layer these on top of the templates above for more precise, reproducible results

01

Layered Context

Stack four layers: spatial context, material-lighting context, atmospheric context, and style tag. Each layer tightens the model's output toward your design intent.

Example

Interior of a university library, double-height reading room, exposed concrete walls, warm oak bookshelves, soft daylight from tall glass walls, people browsing books, eye-level wide-angle, professional architectural photography, 16:9

02

Style and Lens Modifiers

Short style tags bias the render toward a specific look. Hinting at camera and lens gives more controlled compositions: 35 mm wide-angle, telephoto compressed view, documentary-style interior photography.

Example

Residential kitchen at night, under-cabinet lighting, warm interior glow, soft reflections on polished concrete floor, 35 mm wide-angle, interior design photography, 16:9

03

Negative Prompts

Where supported, add these terms to reduce common AI artifacts and keep output at an architectural-quality standard.

Example

no distortions, no deformed hands, no unrealistic proportions, no cartoon style, no low-resolution, no blurry, no text overlay

04

Iterative Refinement

Treat the first render as a rough draft. Tighten language, add specific materials, and adjust lighting across generations until you match design intent.

Example

Change modern → Brutalist concrete · Add backlit onyx countertop · Switch daylight → night with dramatic uplighting

Output Format

Aspect Ratios for Different Use-Cases

Choosing the right ratio improves how your render fits presentations, competition boards, and social media. Always check competition briefs — some explicitly require A1 portrait or A0 landscape.

16:9

Hero renders, video slides, large-screen presentations

4:3

Landscape competition boards, A0-style compositions

3:2

Print-friendly reports, A1 layout-style views

1:1

Detail studies, pattern close-ups, Instagram imagery

21:9

Cinematic panoramas, wide-format exhibition boards

9:16

Street-level perspectives, social-first vertical content

3:4

Portrait competition boards, A1 portrait format

2:3

Tall facade studies, portrait urban perspectives

Workflow

How to Use These Templates with Render AI, Gemini or Google AI Studio

  1. 1

    Copy a template prompt

    Select the category that matches your project (Interior Living, Night Exterior, etc.) and copy the variant closest to your intent.

  2. 2

    Upload your sketch or reference image

    Upload a hand-drawn sketch, screenshot of a 3D model, or reference photo to establish composition and geometry.

  3. 3

    Select the appropriate method in RenderAI

    In the Create App, choose the appropriate method (Super-Fast, Fast-Definition or Creative-Quality). For native 4K output, you need a Pro plan.

  4. 4

    Paste the prompt and add your modifiers

    Add project-specific detail: location context (Mediterranean coastal), style cue (Brutalist concrete), or material detail (backlit onyx countertop with warm LEDs).

  5. 5

    Choose your aspect ratio

    Select from 1:1, 16:9, 4:3, 3:2, 21:9, 9:16, 3:4, or 2:3 based on your presentation format or competition requirements.

  6. 6

    Generate and refine

    Treat the first render as a draft. Tighten language, adjust lighting, and add specific materials across generations until you match your design intent.
