What foundations are needed for a timber frame kit home?

Timber frame kit homes can be built on any standard foundation system: strip foundations with blockwork substructure (traditional, widely understood), raft foundations (fast, suitable for poor ground), screw piles with steel frame (minimal excavation, reversible), and insulated raft systems (Passive House compatible, integrated insulation). The foundation must be level to tight tolerances (±5 mm across the building footprint) because timber frame panels are manufactured to precise dimensions and cannot accommodate significant foundation irregularities.

The foundation must be level to tight tolerances (±5 mm across the building footprint) because timber frame panels are manufactured to precise dimensions and cannot accommodate significant foundation irregularities. Foundation design is always project-specific based on ground conditions — a site investigation is essential before design.
