Timber framing is a simple but elegant building system consisting of large wooden posts and beams that fit together with traditional interlocking mortise and tenon joinery and are secured with wooden pegs rather than nails. The pegs act as a locking mechanism with the joints of the timbers, so that when the frame of the house is assembled on-site, the only element holding the entire structure together is wood. Once the structure is assembled, the walls are completed by in-filling between the wooden structural members with natural building materials such as straw, cob, cordwood or planed wood, or by wrapping the structure with insulation and siding, which creates a tight building envelope. The post and beam framework supports the roof by transferring roof loads to principal posts and onto the foundation of the building, eliminating the need for load-bearing interior partition walls. The result is a strong, self-supporting timber structure with open living spaces, which are easy to heat and cool, and an abundance of energy-saving natural light. A timber frame is structurally stronger than conventional wood construction and uses less wood. It can also employ recycled timbers from other homes and barns. Some in the green building community don’t feel that timber framing is completely environmentally friendly due to its use of wood. However, some critics admit that since it has been recognized and approved by most building code authorities, it is a way of approaching a natural building project that might otherwise have difficulty getting permits. Others point out that the use of natural timbers, as compared to brick, concrete or other fabricated products, can considerably reduce...

Timber
framing or post and beam, as it’s also known, is a traditional style of
construction that is making a comeback. That’s because it creates buildings that
are strong, sustainable and full of character. In Europe and North America,
there are many timber frame structures – homes, churches and barns – that are
centuries old. We’ve even heard of a timber frame temple in Japan that was
apparently built 1300 years ago.
