The main material palette is warm, natural timber slats (cedar) and heavy grey stone base walls. The flat roof is covered entirely in lush greenery (a green roof). Lighting is Golden Hour sunset, making the wood glow softly. The camera perspective is a medium-height drone view, showing the building nestled harmoniously within a natural, slightly sloping terrain.

2D Floor Plan to 3D Version

Nano Banana Pro makes it incredibly easy to turn a flat 2D floor plan into a realistic 3D visualization. Simply upload your floor plan and use a clear architectural prompt for accurate outputs.

Architecture Prompt for 2D Floor Plan to 3D Version: Generate a Top-down 3D Visualization of the floor plan with a rich, inviting interior design magazine aesthetic. The flooring is dark walnut engineered timber with fine grain. The exterior deck uses weathered teak wood. Bathrooms are clad in textured slate-grey subway tiles. Render the 3D furniture with soft textiles (e.g., linen, velvet) and detailed accessories (e.g., plants, books, area rugs). The scene is set against an off-white plaster background. Lighting must simulate golden hour filtering through windows, creating warm, volumetric light rays and long, atmospheric shadows that highlight the coziness of the space.

CAD 2D Illustrations

With Nano Banana Pro, CAD-based 2D illustrations can be enhanced, interpreted, or transformed into richer visual outputs. Try the following prompt.

Architecture Prompt for CAD 2D Illustrations: Render a High-Contrast Elevation Drawing from the source image in a clean CAD style. Use distinct block colors to fill major exterior and interior surface areas (e.g., a light beige for the walls, deep forest green for the roof, and a pale wood tone for the visible floor). All interior furniture and fixtures must be meticulously drawn using sharp, consistent black linework. The overall rendering should maintain the appearance of a structurally accurate section/elevation, presented on a stark white canvas with no shadow or gradient. Style: Technical illustration, solid block rendering, design presentation.

Material and Style Change

Nano Banana Pro can efficiently help every interior designer to change the material, style, and lighting of the room design.
