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.
The hardwood wedges used here instead of pegs can provide an advantage to the frame over time. As the timbers continue to dry over time, especially in a heated interior environment, the wedges can be pounded further into the joint to tighten it again and retain the maximum stability of the framework.
