A side project by Matt Henriksen-Brown

A playhouse, designed down to the last board

I designed a kids' A‑frame playhouse and made everything someone would need to build it: this interactive 3D model and a 65‑page build booklet.

• One source of truth. The whole design lives in a single build model. The booklet and this viewer both come from it, so a part ID in the booklet is the exact board you can click here.
• Show, don't describe. Flat drawings are where DIY builds go wrong. Step through all 13 build stages, turn the model, and tap any board to see what it is and how to cut it.
• Designed like a product. The booklet and viewer share one design system, so the instructions feel as considered as the thing they build.

Proposed design, not engineer-reviewed.
