This is great size frame. 20'x24' story and a half, with a 12' shed on one side. The client wanted a workshop with the option of a small apartment above. It would be perfect for a small home, garage, or guest house. Due to the second floor and roof loads, the structure required even more robust joinery than is typical. The tie beam in the middle of the frame has an oak-wedged and dovetailed mortise and tenon. This same joint was found in a late-18th-century barn in Great Barrington, Massachusetts. Additionally, a step-lapped rafter seat was also necessary for roof thrust. This joint is found on one of the oldest wooden buildings in England, the Barley barn at Cressing Temple, ca. 1200.
