An intersecting steel X on the facade of The Mark tower

ZGF and Arup integrate form and structure with steel knuckles in The Mark

The Mark is a 750,000 SF, 48-story commercial office and hotel tower that’s reshaping the Seattle skyline, and designed to preserve the historic Jacobean-style Rainier Club and the nation’s oldest Byzantine-style church next door. Utilizing a compact footprint at ground level, the tower subtly slopes over the site’s existing structures before tapering back through a precise system of steel “knuckles” and triangulated building planes.
