InterActiveCorp (IAC) Headquarters

ACEC New York Platinum Award | BOMA Pinnacle Award 

The first full building Gehry designed in New York City, the 10-story IAC Headquarters departs from conventional commercial architecture. Its massing undulates fluidly along its West Chelsea street frontage, evoking the motion of sails in the wind, and retreats gradually as the building rises in height.

To design a structure that could meet the unusual complexity of the two-tiered building, DeSimone first completed a detailed load analysis and precision layout, which informed our solution: a cast-in-place, reinforced concrete frame.

Concrete slabs cantilever outward, carrying the weight of the curtain wall at varying distances in sync with the ebb and flow of the curvilinear form.

Our team’s structural design optimized asymmetrical loading from the cantilevered upper stories and created a column-free lobby and other long, open interior spans.

Vertical structural elements slope as much as 25 degrees. To address the irregular building perimeter and sloped columns, we specified custom formwork, which was selectively re-used for similar atypical elements in other areas of the structure to reduce costs.
The structure was carefully conceived to conform with the building’s flowing, sculptural envelope—a highly distinctive, curtain wall façade made of nearly 1,350 curved glass panels, cold-warped on site, that gradually fade from white at the edges to clear in the middle, creating an ombré effect.
