🏠 House Build Sequence Lab: Concrete Curing, Joist Bending and Roof-Truss Snow Load

Build a timber-frame house in 3D by sequencing the trades: footings, floor, walls, trusses, roof and cladding. Concrete strength grows with temperature-adjusted maturity and gates each trade; floor joists are checked in bending, shear and deflection, and a pin-jointed roof truss is solved for dead, imposed and snow loads, with schedule and cost.
