Timber framing and Post and Beam framing are often thought to be the same by the average person, but they are really quite different when it comes down to the details. Both techniques leave the trademark look of fully exposed beams on the inside of the structure.
The main difference between timber framing vs post and beam framing is the way timbers are connected to each other. Timber framing uses mortise and tenon joinery along with wooden pegs whereas Post and Beam framing uses half-lap joinery with hidden fasteners, and oftentimes metal bracing.
So what does mortise and tenon joinery mean? Let’s break it down. The mortise is the side of the wood with the hole in, the tenon is the side with what is called the tongue tenon on it. The tongue tenon is a section of wood that is cut to lock into the mortise side of the joint. After the joint has been put together, it will be glued, pinned, or wedged to lock it in place. It is one of the oldest, longest used joint methods. Timber framing offers an organic, structurally sound building option. Timber frame bents (or sections) are assembled on the ground and then raised into place. The raising process is sometimes seen as a ceremonial moment since you are able to really see your home take place quickly.
Post and Beam construction came about after the Industrial Revolution when machine-made products, such as the fasteners and metal bracing, were more easily available. The main characteristic that sets post and beam apart is the beams are set on each other and connected with metal, such as bolts and plating. This created a less intricate connection. These are much more visible joints, even though they can be strategically placing to limit being seen.
