Waechter Architecture completes “all-wood” building with steel jacket recently profiled an “all-wood” commercial building in Portland, Oregon which claims to be the first commercial building in Oregon to “use mass timber construction for all components of the building”. Waechter Architecture completed that project.  The building, called Mississippi has structural elements made from cross-laminated timber (CLT) panels and glued-laminated timber (glulam) beams.

Apart from the exterior weathering steel “rain jacket”, rock wool insulation, and radiant concrete flooring, all of the surfaces of the building are exposed wood, “without any need for additional finishes or fireproofing”.

The only non-wooden elements are the steel, concrete flooring and insulation, and was designed to be easily constructed and have high energy efficiency The studio has received funding from a USDA Wood Innovation Grant to map the buildings’ performance.
