What is Stairsmith?
StairSmith is a free, open-source 3D stair creator that runs entirely in your browser. Enter your dimensions (going, rising, width, headroom, floor-to-floor height) and the online staircase designer generates a fully resolved 3D staircase preview in real time using Three.js. All geometry computation happens client-side through Pyodide and Shapely, so there is nothing to install and no data leaves your machine.
The 3D stair creator checks compliance with Approved Document K dimensional constraints as you adjust parameters, giving immediate visual and numerical feedback on whether a design satisfies UK Building Regulations. Outputs include IFC4X3 for BIM workflows and DXF for 2D drafting, making it straightforward to take a tested design into your CAD or BIM environment.
Built by Jake White, a Chartered Architectural Technologist based in West Sussex, this online staircase designer was created to solve a practical problem: quickly testing staircase options during feasibility and technical design without opening full CAD software. It is free to use at jakewhitearchitecture.com.
