In response to your question, the definition of post & beam in this case is a structural frame formed by connecting columns (posts) and beams to form an enclosed space suitable for living or working or storage. The structural members in this case would be glulams or engineered wood (LSL PSL), so I am hestitant to call it a timber frame, the nature of the system requiring tolerances far in excess of what can be expected of solid wood, so that the product is likewise of much higher quality in fit and finish than that of a conventional timber frame. The connections are made using ICC-ES listed concealed metal connectors held in place with 1/2" metal drift pins. We have produced over 30,000 units using this method overseas. YMHOS
