Berge Sag supplies timber-frame houses, cabins or residential developments through catalogue designs and project-specific construction. Berge Sag supplies houses and cabins through catalogue and customised timber projects, with roots in sawmilling and building materials.

Catalogue plans provide the starting point, while the final building is adapted to the plot, room programme and local requirements. Services are delivered through local offices, dealers or construction teams and can cover plan adaptation, technical design, permit coordination, pricing and site construction.
