Last week we released Nano Banana Pro (Nano Banana 2) inside Fenestra, and honestly, it’s been one of the most interesting upgrades for architects and interior designers so far.

It’s much better at understanding space, layout and structure - which means it’s finally viable for turning simple 2D plans into convincing, spatially-aware visualisations.

Here’s a quick workflow you can try today:

1. Create a top-down 3D version of your plan

Upload a floor plan and open Conversational Edit.

Select Nano Banana Pro from the model list.

Try this prompt:

Create a top-down 3D rendering of this 2D floor plan. Show furniture in three dimensions. Use timber flooring, a timber deck outside, and tiles in the bathroom. Place everything on a clean white background with soft daylight and long shadows.

You’ll get a top down render that respects the plan layout surprisingly well.

Follow Along in Fenestra

Render with Nano Banana Pro!

2. Axonometric from your rendered 3D plan

Continue in Conversational Edit

Try this prompt:

Turn this top down 3D plan rendering into a axonometric illustration on a white background maintaining the style of the home

You’ll get a axonometric you can use to blend between using Seedance 1.0 Lite for any animations like the GIF at the top of the page.

3. Add style & materials with “Add Anything”

If you want to push it further, use Add Anything with a reference interior image.

Prompt example:

Based on this material sample reference, bring the style and colour into this floor plan while keeping the layout intact.

Material references work really well, just ask Nano Banana Pro to apply specific finishes, which is useful for quick visual ideation with clients.

4. Create CAD 2D Illustrations 

Nano Banana Pro is great at creating flat 2D block color illustrations. Perfect for when you’re trying to dial back the realism to show a client options and intent without them getting lost in specific details. Try this prompt:

Turn this image into a cad styled elevation with block color, with all the details of the interior image shown clearly with linework.

This model can do so much more, explore it, it’s fantastic at new camera angles and macro shots, you can learn more about that here

Once you've got a view you like, Realtime is the faster way to push it around, it keeps the render updating at 15+ FPS while you move the camera or swap materials.

Use Nano Banana Pro!
