We recently visited The Barn Yard in Ellington, CT for a tour of their manufacturing facilities. They are a timber framing fabricator and installer, offering kit buildings as well as fully customized timber frames for large homes and barns. They utilize a computer-controlled 5-axis CNC mill to recreate traditional barn construction details and joinery in several different species of wood, but with higher precision and speed than working by hand. These joints are fastened with oak pegs instead of screws and nails, and create a beautiful and long-lasting exposed structural frame for the building. You can learn more about the process here.
