Post and beam and timber frame are both beautiful methods of building but most people are think of them as one and the same. Although they are similar, there are subtle differences between them. Both are methods of building that create a frame that is self-sustaining and carries the weight of the house. The main difference in the two types is the method of joining the parts.
Timber frames are always made with solid wood with mortise-and-tenon connections and secured with wood pegs. Post and beam construction typically uses half lap joinery with hidden fasteners, and decorative metal braces some of the time.
The other difference is in the type of wood that is used. Post and Beams can be constructed using engineered wood such as glulams or glued laminated timber (a type of structural engineered wood) and can have metal connectors. Timber frames are constructed using only solid timber.
Because the frame carries the weight of the house with both methods, interior load-bearing walls aren’t necessary, allowing for large open interior spaces and high ceilings. Often the frame is left exposed, adding a natural beauty to the look of the house; in some cases the frame is hidden behind walls. Most post and beam/timber frames are preconstructed in a protected environment, then are labeled and trucked to a site where they are quickly erected. Often the wood used for these frames is recycled wood or standing dead timber. If the house is later deconstructed, these timbers can then be used for future structures.
Timber frame houses are often more costly than post and beam because of the precision and intensive labor required to fit all of the joints. These are generally built by very trained craftsman and recently with the precision that comes with a CNC (Computer Numeric Control) milling machine.
Often both of these types of home are completed with structural insulated panels (SIPs) or panelized components. Both methods create a very efficient and beautiful structure.
