2D floor plan to 3D apartment

Apartment3D

Turns a 2D floor plan into a structured scene graph, generates watertight 3D geometry, furnishes it with an LLM and a constraint solver, and lets people customise it in natural language.

The challenge

Going from a flat drawing to a furnished, photorealistic 3D apartment normally takes a 3D artist days — and every change request starts the loop again.

What we built

A pnpm monorepo of TypeScript services: a parser that produces a validated scene graph, a deterministic geometry engine that emits GLB, a layout service that furnishes rooms with an LLM plus constraints, MCP tools for natural-language edits, a Three.js viewer in the browser and Blender Cycles workers for final renders.
