What is Timber Framing?

Timber Framing

A centuries-old craft in the Northern Hemisphere, timber framing is a building technique that usually involves stout, solid-sawn beams and posts that are shaped at their connections to lock together.

Compared to typical light frame construction, in which slender sticks of wood are cut to length and nailed together, timber framing typically uses fewer wooden members that are affixed by mortise and tenon or other kinds of joints with wooden pegs.

Another key difference is that light-framed buildings are invariably concealed by finished walls and ceilings, whereas timber frame work is generally exposed and highlighted as design attributes of the architecture.
