The Bossio project was designed by Whippletree Timber Framing. This building had a very tight production schedule, so timber cutting was done by four shops, Whippletree cutting the top plates, purlins, west posts and entrance, Traditional Timberworks cutting the main posts and tie beams, Discovery cutting the upper trusses, and Ivan Vallier cutting the braces. This large frame, at over 4,000 square feet, was designed, cut and raised in under 4 months.
