Taking a nine-story Class B warehouse at 441 9th Ave. at the corner of 34th Street in Manhattan and transforming it into a modern 26-story Class A structure was a feat requiring expert top-to-bottom strategic planning and execution.

The team on the 700,000-sq-ft Hudson Commons not only gutted interiors and installed new infrastructure and interiors, it also reinforced foundations to build 17 new stories with high ceilings, natural lighting and outdoor spaces.

The work entailed adding a new structural core and reinforcing columns and foundations with 48-in.-thick spread footings, a new shearwall and rock anchors, column “jackets” of rebar cage and shotcrete, and additional micropiles. All of that work—along with reinforcing the existing cast-in-place concrete slabs with structural steel and tying them to the new core—allowed the team to open slabs and significantly brighten the lower nine floors, which now have glass panels and expanded windows.

The new stories feature an all-glass facade and 14-ft ceiling heights. Nearly every level has private terraces or balconies.
