Nano Banana for Architects: Pro Tips and Prompts to Save You Hours

Nano Banana (officially called Gemini 2.5 Flash Image) is Google’s latest AI model for fast image generation and editing.

For architects and interior designers, it’s a game-changer: instead of going back into SketchUp, Revit, or Photoshop, you can make instant edits to your renders just by typing what you want changed.

Need to swap siding materials, remove a distracting object, or test your scene at sunset? With Nano Banana, it all can be done in seconds, without 3D software or manual retouching.

How to access Nano Banana

There are several ways you can edit your architectural renders using Nano Banana, depending on your workflow and tech setup:

1. Through the Gemini mobile app.
2. Through Google AI Studio, available on the web.
3. Via API. You'll need a developer to set it up.
4. Via third-party software like MyArchitectAI, which is by far the most user-friendly option. This way, you don’t just get Nano Banana, but also access to AI rendering, style transfer, enhancement tools, and more, all in one place.

In this guide, I’ll focus on the MyArchitectAI workflow, since it’s the easiest way for architects and designers to get the most out of Nano Banana.

Best Nano Banana prompts for architects and designers

For our tests, I started by rendering the SketchUp design below using MyArchitectAI's AI rendering engine.

Let's now see what’s possible using Nano Banana for render editing.

Removing objects

No more Photoshop. Simply describe the object to erase from your render.

Prompt: "remove the red chairs from the patio"

‍

Adding objects

Nano Banana lets you add people, furniture, vegetation, or context. You can use text prompts or upload reference images for higher precision.

Prompt: "add a blurred couple in their 30s standing and talking on the patio on the right side of the building"

‍

Swapping materials

Nano Banana is great for material studies. Simply attach the new material image, and instruct it where to apply it.

Prompt: "replace the roof material using the one from the attached image"

‍

Changing atmosphere

Nano Banana lets you instantly test different lighting, weather, or seasons.

Prompt: "turn it into a dusk scene, soft light glow from inside the building"

‍

Shifting camera angles

One of Nano Banana’s most impressive features is shifting perspective while keeping the scene consistent. Notice how in the example below, the details of the main subject are kept unchanged.

Prompt: "show the building from a bird's eye view, suburban landscape around"

These same edits also work beautifully for interior renders. Whether it’s trying new flooring, swapping furniture, or adjusting the mood. Here are some more examples:

Wrapping up

Nano Banana makes render editing faster, easier, and more intuitive than ever.

Whether you’re testing new façade materials, cleaning up presentation images, or adjusting a client’s last-minute request, the tool handles all the manual work for you.

For architects, it means less time stuck in software menus and more time focusing on design and creativity.

And when you pair Nano Banana with MyArchitectAI, you unlock a complete rendering workflow: from SketchUp model to photorealistic render to quick editing, all powered by AI.
