The Spar

Once complete, The Spar will stand as the tallest mass-timber building in the world.

In May 2018, Kaiser Group received a $250,000 Wood Innovation Grant from the USDA Forest Service to conduct feasibility research on The Spar, which is designed for a site in downtown Portland. Research and construction will pave the way for more mid- and high-rise wood construction in the Pacific Northwest and beyond.
