How AI Turns a 2D Floor Plan into a 3D Walkthrough Video

Designers often spend a lot of time turning flat floor plans into intuitive 3D presentations. The following workflow shows how AI tools can automate most of that work while preserving design consistency.

Step 1: From 2D to 3D Overview

Upload the 2D floor plan, create a "list node" that contains different design styles, and add an "image node" with style prompts. Generating with tools such as Nano Banana Pro quickly produces several 3D overview images that keep the original layout.

Step 2: Deepening Each Room

Using the image list from step 1, create a new "image node" for each room to generate interior renders. The key is to keep spatial consistency—style, scale, and overall scheme remain unified across rooms.

Prompt Engineering

To make the generated images match the design intent, the article provides a prompt template that describes space, style, material, and atmosphere in detail.

Step 3: Enriching Video Content

Generate additional images—such as realistic photos with people or a studio logo—to add rhythm and branding to the final video.

Step 4: Generating the Dynamic Walkthrough

When all static frames are ready, use a video generation tool such as Kling 3.0. Set start and end frames for each scene, carefully designing the camera path to produce a smooth, continuous walkthrough.

The article also provides a sample video‑generation prompt that emphasizes camera motion.

Overall, this workflow demonstrates how AI can act as a “super‑collaborator” for designers, turning labor‑intensive 3D modeling and rendering into a prompt‑driven creative process that lets designers focus on spatial aesthetics and user experience.
