Design buildings by describing them.
Fivelegfox is an AI-native architecture design tool. Describe your building in natural language, and our agentic AI creates and modifies 3D IFC models in real-time.
Early preview, not the final version yet — but it works, and it's open to everyone.
From chat to 3D model
How it works
1 Describe your building
"Create a small apartment with a living room, bedroom, kitchen, and bathroom"
2 Refine through conversation
"Add furniture, windows, and a door to the living room"
3 Export production-ready IFC
Get BIM-ready IFC files with proper spatial hierarchy for professional use

A live sneak peek of Fivelegfox is open to everyone — no signup needed. It's an early preview, not the finished product, so you may hit some rough edges. But everything you create exports to real IFC.
