Postcard of the day, December 09, 2010

Folks often ask us the difference between post and beam and timber framing; here's the first postcard in a series on this topic. Where timber framing uses mortise and tenon joinery to connect the timbers, post and beam structures are usually stabilized by metal plating and gravity. Post and beam is known for vertical and horizontal timbers, where timber frames often make creative use of braces, even designing lyrical curves into the design. This outdoor pavilion at the Tualatin River National Wildlife Refuge is a good example of post and beam.
