Through tenon joints have a very appealing aesthetic, and they can be interpersed with other joints to keep the eye interested as it travels through a frame.
In traditional timber framing, wood joinery is used to fit all the timbers together in an exact pattern, with braces lending structural rigidity and solid oak pegs tying all the pieces together.
The bents for this frame were assembled beside the building and stacked until the day of the raising. Each individual timber is separated cut, notched, and finished before putting them together into the bents (or wall sections).
