Bullitt Center the first Mass Timber Building in Seattle in 80 years

The Bullitt Center, arguably the “greenest office building in the world” was the first mass timber commercial building constructed in Seattle in over 80 years. It has a structural frame of glulam columns and beams, floor decks of 2×6” lumber set on edge and “nail-laminated” together, and plywood used for structural diaphragm and shear wall panels – all conforming to prescriptive code requirements. 100% of the wood used in the project was FSC certified from local sources to meet the rigorous standards of the “Living Building Challenge.”
