We’ve combined this ancient building style with modern technology and an ecological sensibility using the latest structural insulated panels (sips) to save energy costs. We used old fashioned braced frames that incorporate the ancient and sturdy mortise & tenon joinery held together with wooden pegs. If you opt for more intricate designs, in order to fit more stringent local code requirements, the frames may require engineered connectors in some joints. These connectors will be hidden in the timber and not attached to the timber surface.
