Gemini Nano Banana Pro Prompts for Architecture 3D Visualization, BIM, and AI Rendering
I’ve been watching AI image generation closely, and Google’s latest model, Gemini Nano Banana Pro, has genuinely impressed me.
It’s producing photorealistic 3D visualizations that look like they came straight from professional rendering software. As an architect or designer, this changes how you can present ideas to clients and speed up your workflow.
How to Get Started
Go to gemini.google.com, start a new conversation, and select the “Pro” version. Then paste one of the prompts below. If you want to add context, upload reference photos as well. The model will handle the rest.
These prompts are basic, so make sure to add your own ideas to these prompts.
Architecture 3D Visualization Prompts
Modern Residential Exterior with Golden Hour Lighting
Create a photorealistic 3D exterior render of a modern two-story residential house with exposed concrete walls, large glass windows, and wooden facade accents. The building is surrounded by minimal landscaping with small trees and grass. Golden hour lighting creates soft shadows and warm reflections. Professional architectural visualization quality. Use aspect ratio 16:9.

Create a detailed cutaway 3D view of a modern house showing interior spaces, staircases, floor levels, and roof structure. Soft neutral lighting and professional architectural presentation style. Use aspect ratio 16:9.

High-Rise Building Floor-by-Floor Cutaway
Create a 3D cutaway visualization of a high-rise building revealing floor-by-floor layout, structural core, elevators, and staircases. Clean background with balanced lighting and realistic proportions. Use aspect ratio 16:9.

Villa Component Assembly Diagram
Create an exploded architectural diagram of a villa showing foundation layers, structural frame, walls, facade panels, and roof elements arranged in sequence. Professional visualization suitable for client presentations. Use aspect ratio 16:9.

Interior Architecture Prompts
Modern Living Room with Double-Height Space
Create a realistic 3D interior architectural render of a modern living room with double-height ceiling, concrete flooring, wooden wall panels, and large glass windows. Natural daylight creates soft shadows and realistic reflections. Use aspect ratio 16:9.

Modern Kitchen Design
Create a professional 3D interior visualization of a modern kitchen with clean cabinetry, stone countertops, integrated appliances, and warm under-cabinet lighting. Neutral color palette with realistic material textures. Use aspect ratio 16:9.

Luxury Bedroom Interior
Create a high-detail 3D interior architectural render of a luxury bedroom with minimal furniture, textured walls, wooden flooring, and soft natural light entering through large windows. Calm and balanced composition. Use aspect ratio 16:9.

Open Office Workspace
Create a modern office interior architectural visualization with open workspace layout, glass partitions, ceiling services visible, and ergonomic furniture. Even lighting and realistic spatial depth. Use aspect ratio 16:9.

Hotel Lobby with Double-Height Space
Create a realistic 3D interior render of a hotel lobby with double-height space, marble flooring, modern seating, and warm ambient lighting. Professional architectural visualization quality. Use aspect ratio 16:9.

Urban Planning and Master Plan Prompts
Modern Residential Township Aerial View
Create a detailed 3D aerial master plan visualization of a modern residential township with apartment blocks, internal roads, green parks, parking areas, and pedestrian pathways. Clean layout with realistic scale. Use aspect ratio 16:9.

Mixed-Use Development Overview
Create a professional 3D urban planning visualization of a mixed-use development showing residential, commercial, and recreational zones clearly defined. Soft daylight and top-down aerial perspective. Use aspect ratio 16:9.

Coastal Urban Development Waterfront
Create an aerial 3D visualization of a coastal urban development with residential blocks, promenade walkways, green spaces, and waterfront structures. Natural daylight and clear spatial organization. Use aspect ratio 16:9.

Institutional Campus Site Planning
Create a detailed 3D site planning visualization of an institutional campus with academic buildings, hostels, internal roads, landscaped areas, and open courtyards. Professional architectural presentation style. Use aspect ratio 16:9.

These prompts are starting points. They give the AI enough direction without being overly complicated. The aspect ratio specification helps maintain consistency for presentations. The material and lighting details ensure the output looks professional.
The key is being specific about lighting, materials, and composition. Vague requests produce vague results. These prompts eliminate that guesswork.
Start with one. See what you get. Then adjust based on your specific needs. That’s how you’ll get the most out of the tool.
