Keep the massing white
Plain white or grey volumes with shadows on. Context buildings in a slightly darker grey help separate them.

Before you start
Prepare your massing model view
Early massing studies are about volume, height and how a building sits in its context. Export the white model, describe a facade approach and the setting, and test several architectural expressions on the same massing in RenderChat.
Choose the eye
A street-level view tests how the building feels; an elevated view tests how it sits in its block.
Write the facade idea
Describe the facade approach in a sentence: brick with deep reveals, a glass box with fins, timber screens.

Prepare your massing model view
Keep the massing white, choose the eye and write the facade idea. The checklist above has the details.
Open RenderChat with Nano Banana Pro
The start button on this page opens a new chat with Nano Banana Pro selected. You can also pick it from the model menu in the composer.
Upload and write the brief
Attach the image and say what must stay, then the materials, light, setting and people. Start from an example brief below.
Refine in chat
Ask for changes in follow-up messages. Nano Banana Pro continues the same conversation, so a short instruction such as "warmer light, keep everything else" is enough.
Download the render
Download the image at the resolution you chose (1K · 2K · 4K).
Example briefs
Massing model briefs to start from
Copy a brief, paste it into RenderChat with your massing model view, and change the materials and mood to match your project.
Turn this massing model into a photoreal street-level render. Keep the volumes and heights exactly. Red-brown brick with deep window reveals, a glazed ground floor with shops, street trees and people, overcast light. Render the grey context buildings as existing city blocks.
Same massing and camera. Facade of floor-to-ceiling glass behind vertical timber fins, planted roof terraces, warm evening light.
Nano Banana Pro in RenderChat
Working with Nano Banana Pro
Google's Gemini 3 Pro Image model, known as Nano Banana Pro. RenderChat runs it as a native conversation and accepts a large reference set, part of which can be sent at high fidelity.
- Put the references that must be followed closely (a facade material, a furniture piece) first.
- Name what must stay fixed — massing, openings, camera — before what should change.
Quality check
What to check before you share it
- Heights and setbacks — massing is the one thing that must not change.
- The number of floors the AI implies through windows.
- Context buildings staying in the background.
