Furnish it in a warm Scandinavian style: light oak floors, a grey sofa, a dining table for four, a bed with linen bedding and plants in every room. Soft daylight, realistic materials, clean white background, no text labels.

Photo edit prompt guide
Which photos work for this edit
A furnished, isometric 3D cut-away of a home, built from one floor plan, is what Nano Banana 2.1 produces from this prompt. The walls rise to ceiling height and are cut open from above, with the rooms, windows and doors kept in the same places as the drawing. It works because the plan locks the layout while the furniture list and soft daylight set the style, so the render stays faithful to the plan.
Use one clean floor plan as image 1. The model reads its walls, openings and room shapes, then builds the 3D render on top of them.
- Works: a clear floor plan drawn from above
- Thick, unbroken walls and visible window and door gaps give the model firm lines to raise to ceiling height and keep in place.
- Works: a single-level plan with all rooms in one frame
- The cut-away view shows every room from one high angle, so a plan split across pages or levels will leave parts of the home out.
- Avoid: photos of a real room or a house exterior
- A photo has no clean wall lines to convert, so the model has to guess the layout and the walls will not match the rooms the prompt asks for.
- Avoid: plans crowded with dimensions, notes or hatching
- Extra marks can be read as walls or objects in the 3D render, which clutters the clean white background the prompt asks for.
What each instruction does
- core edit request
Convert the floor plan in image 1 into an isometric, photo-real 3D cut-away render of the home
This sentence sets the job: turn the drawing into an isometric, photo-real 3D model of a home. Remove it and the model may return a flat plan or a single room instead of a full cut-away house.
- cut-away and layout lock
walls raised to ceiling height and cut open from above, with the same room layout, windows and door positions as the plan
This is where the cut-away and the layout come from: walls at full height, sliced from above, with openings in the same places. Without it the walls stay low and the windows and doors can drift to new spots.
- style and main furniture
Furnish it in a warm Scandinavian style: light oak floors, a grey sofa, a dining table for four
The style words and the furniture list set the look of each room. Drop 'warm Scandinavian' and the look turns neutral; cut the list short and the rooms are left bare.
- bed and plant details
a bed with linen bedding and plants in every room
The bed and plants add lived-in detail to the bedrooms and living areas. Removing them makes the render feel empty, while adding more props can crowd the small rooms in the plan.
- light and backdrop
Soft daylight, realistic materials, clean white background, no text labels
This sets the render's lighting, surfaces and backdrop. Without 'Soft daylight' the shadows can turn harsh, and without 'clean white background' the model may add a room or street behind the house.
Other edits in the same pattern
Studio apartment in Japandi style
Swaps the house for a smaller studio and a calmer palette, for a plan with fewer rooms and tighter spaces.
Prompt
Convert the studio floor plan in image 1 into an isometric, photo-real 3D cut-away render of the apartment: walls raised to ceiling height and cut open from above, with the same room layout, windows and door positions as the plan. Furnish it in a calm Japandi style: pale ash floors, a low linen sofa, a compact dining table for two, a futon bed with cotton bedding and plants by every window. Soft daylight, realistic materials, clean white background, no text labels.
Family house in Mediterranean style
Keeps the same edit and changes the materials, the table size and the light, for a larger family plan with a warmer look.
Prompt
Convert the floor plan in image 1 into an isometric, photo-real 3D cut-away render of the home: walls raised to ceiling height and cut open from above, with the same room layout, windows and door positions as the plan. Furnish it in a warm Mediterranean style: terracotta tile floors, a cream sofa, a dining table for six, a bed with striped cotton bedding and olive plants in every room. Warm late-afternoon light, realistic materials, clean white background, no text labels.
Winter evening version
Use it when you want the same plan shown as a moody night scene, with the lamps lit and darker materials.
Prompt
Convert the floor plan in image 1 into an isometric, photo-real 3D cut-away render of the home: walls raised to ceiling height and cut open from above, with the same room layout, windows and door positions as the plan. Furnish it in a cozy winter style: dark walnut floors, a charcoal sofa, a dining table for four with wool throws, a bed with grey linen bedding and fir plants in every room. Warm lamp light at dusk, realistic materials, clean white background, no text labels.
Model and settings
Keep the 4:3 ratio and 1k resolution from the example, since the plan and the render both fit a landscape frame and the clean white background stays even at the edges. Use image-to-image mode with your floor plan as the one input picture, so the walls and openings are edited rather than redrawn from nothing. If you want a square post, change the ratio, and check that the walls still line up with the plan before you keep the result.
- Nano Banana ProChoose this if your plan is dense with notes or needs a stricter layout. Its tagline says it plans the layout first, which suits keeping every wall and opening where the drawing puts it.
- Seedream 5.0 ProChoose this if you want to add reference photos of your own furniture or finishes. Its tagline says it takes detailed edits from up to ten references, so the room style can follow your pictures.
When the edit misses
- The walls drift away from the plan, so room sizes and door gaps no longer match the drawing.
- Keep 'with the same room layout, windows and door positions as the plan' word for word, and add 'keep every wall where it sits in image 1'.
- The whole picture gets repainted into a new scene, and the outline of the plan is lost.
- Start the prompt with 'Convert the floor plan in image 1' so the edit targets that picture, and remove any scene words that are not in the plan.
- Shadows fall from different directions, so the furniture looks pasted onto the floors.
- Keep 'Soft daylight' and add 'one light source from the upper left, with matching shadows under every sofa and table'.
- The output comes out in the wrong shape, so the full cut-away does not fit the frame.
- Check that the ratio is still 4:3 as in the example, or set the ratio that matches your plan's outline before you generate again.
Questions about this edit prompt
Can I use a hand-drawn floor plan with this Nano Banana 2.1 prompt?
Yes, if the walls are dark, continuous and the window and door gaps are clear. Faint sketches can lose wall thickness, so the raised walls may not line up with the rooms in your original drawing.
How do I stop the furniture from changing the room layout?
Keep the layout sentence and the furniture sentence separate, and do not add items beyond the list. A long furniture list can push the model to shift walls so the objects fit.
Why does my render still show room names when the prompt says no text labels?
The prompt ends with 'no text labels', which asks the model to drop room names and dimensions from the plan. If labels still appear, put that phrase earlier in the prompt and generate again.
