How to incorporate partial timber frames into a conventionally-framed home

Timber roof systems


A timber roof system can be used in combination with conventional framing to provide the beauty and strength of timbers throughout.

Timber Trusses

A truss system can create a unique vaulted roof for, as an example, a 16' family room wing.

Principal rafters are 8 x 8 or 8 x 10. Purlins are 6 x 6 or 7 x 7, locked with dovetail tenons and oak wedges.

Principal rafters are notched to sit on stud wall. They can be spaced up to 16' apart.

So the post isn't needed to carry weight, but it helps to define the different rooms - an important feature in an open concept design.

Here are a few of the many possible truss configurations:
