565 Broome
SoHo’s tallest residential building—and the first NYC luxury condominium building to be certified as Zero Waste— 565 Broome began with the creative assembly of multiple parcels to create a large, unified, rectangular site for the two, mirror-image glass towers sitting atop a 12-story podium.
For this Renzo Piano Building Workshop-designed complex, our structural engineers designed a concrete slab-and-column structure and resolved some key project challenges along the way. When original plans for an enclosed bridge between the two towers changed, we pivoted and designed the structure for a dramatic, 92-foot-high glass atrium to fill the space between the two towers’ inner concrete structural walls.

At the setback level, where swimming pools and landscaped gardens added to the significant gravity loads from the towers above, our engineers utilized a transfer slab at the 12th floor to shift columns on the upper part inward and deep transfer beams at the 11th floor to shift columns outward to redirect and boost structural support.
A new basketball court, promised to a neighboring school and youth center as part of the site negotiations, required a large, column-free space, so we designed the ground floor above the court as a 24-inch-thick, 50-foot-long voided concrete slab.
We also designed custom elements, like built-up steel plate tubes to support the façade without a slab connection in open areas and steel hanger rods to support the cantilevered second floor slab in the retail space.
