How Google Nano Banana AI Transforms Architecture Design?

In a matter of a few minutes, you will learn how to use Google's Nano Banana to create images, edit images, turn images into 3D models, convert a Google Earth building into a 3D model, turn a simple floor plan into an image, and how to remodel or reimagine your room, home exterior, and landscaping.

How Google Nano Banana AI Transforms Architecture Design?

Nano Banana is a state-of-the-art image generation and editing model created by Google. This is the AI model used for the entirety of this tutorial. The hardest part about writing a good prompt is knowing what you want.

Generate and Edit Images with Google Nano Banana

Image to 3D Model with Google Nano Banana

Create a source image:

• Type: domed earth home in the desert. There are circular windows and the home has two stories in some rooms. Aerial drone shot. High quality architecture rendering.
• Hold Control and press Enter.

Prepare the image for 3D:

• Tell Nano Banana to remove the entirety of the landscaping so the building is just a simple 3D model with no background.
• Hold Control and press Enter.
• Download the image.

Convert to 3D with Meshy AI:

• Open a new tab and search for Meshy AI. Create an account.
• Go to Workspace at the top, hover, and select Image to 3D.
• Tip: If you pay for Meshy, you can do batch images to 3D by inserting multiple images from different angles to create a more accurate 3D model. It creates a much more accurate 3D model.
• Click in the upload box and upload your image.
• Under Symmetry, select Auto and click Generate.
• On the right hand side, Meshy is generating the 3D model. Click the box to open it.
• Scribe through the boxes to rotate the 3D model and find which one you like the most. Select it and choose Yes for Generate texture. Confirm.
• When texture generation is complete, click it to view your 3D model.

Create 3D Model from Google Earth with Google Nano Banana

Capture multiple angles:

• Search for Google Earth and open it.
• Click New for a new project. Search for the building you want to turn into a 3D model. Example: the Eiffel Tower.
• Click 3D on the bottom right and zoom out until you see it in its entirety.
• Open your snipping tool. Click New and capture an image. Save it in a dedicated folder.
• Hold Shift and click inside of your target. Rotate slightly to get a different angle. Create another snip and save it.
• Continue until you have a 360 of the entire building.

Create a composite with Nano Banana:

• Go to Google AI Studio Nano Banana.
• Click the plus icon in the prompt bar and upload all your screenshots.
• Paste your prompt for combining the views and hold Control and press Enter.
• Nano Banana will create a 3D-looking representation. This image is not 3D itself. It’s a JPEG. Download it.

Convert to 3D with Meshy AI:

• Open Meshy AI, go to Workspace, and select Image to 3D.
• Upload the image that Nano Banana created.
• Set Symmetry to Auto and click Generate.
• After it hits 100%, click it and scribe through the 3D model to see which one is most accurate.
• Click your preferred result. In the popup, set Target poly count to Max, Generate texture to Yes, and confirm.
• After texturing reaches 100%, click the box to view the 3D model. Click and drag to rotate. You can download it in the bottom right.
• At the time of writing it is free to download these models, but it’s likely that they change this over time. If that’s the case, simply search for AI image to 3D model generator, and the workflow is likely very similar.

Floor Plan to Rendering with Google Nano Banana

• Go to Google AI Studio Nano Banana.
• Click the plus icon to upload your floor plan.
• Paste your prompt, edit as needed, and click Run when you’re done.
