HS2 was the executive architect for the LEED Silver certified Chanel NYC flagship boutique, designed by Peter Marino Architect.

The renovation and expansion of the existing 57th Street boutique saw the flagship grow from 3 to 6 floors, with a new 6-story oversized aluminum and glass façade, completely new interiors and a monumental 4-story white marble cantilever staircase. A 60-foot-tall glass-bead necklace sculpture by the artist Jean-Michel Othoniel hangs in the stair opening, connecting the four main retail floors.

In addition to the boutique, several floors of Chanel office and showroom spaces were also built-out on the upper floors of the 16-story building.
