Since timber framing and post and beam are structural construction methods, your options to enclose the building are vast, including anything from structural insulated panels (sips), straw bale with an adobe or concrete finish, or your standard 2x6 stud walls with fiberglass insulation. For barns or other structures that don’t require insulation, classic clap board siding over 2x4 non structural framing is one of the most flexible and locally sourced ways to build today. For example, you could source your timbers and straw bales locally to have about 80% of your home built from local materials. Additionally the raising and even straw bale construction phases of the project could be done with the help of your local community and friends. They also make lovely cozy tiny houses, not to mention solid and beautiful solar pergolas, and car ports.
