What’s better than skyline-altering tower by a globally renowned starchitect? Why, two skyline-altering towers by a globally renowned starchitect, of course. When Bjarke Ingels’s The Eleventh tops out, its two twisting towers are likely to become as eye-catching as the architect’s VIA 57 West. And in West Chelsea, where the list of creators behind new buildings reads like a who’s-who of the best architects in recent history—Zaha Hadid, Peter Marino—it’s no easy feat to stand out. It’s only fitting, then, that the interiors of Ingels’s two buildings, which will house several luxury residences as well as the first U.S. location of Six Senses Hotels, are undertaken with equal care. In this case, the project (developed by HFZ Capital Group) has fallen to not one but two firms, giving each tower a unique, yet undeniably location-specific aesthetic. AD PRO chatted with Gabellini Sheppard’s Michael Gabellini and Kim Sheppard (west tower) and Gilles & Bossier’s Dorothée Bossier (east tower) about their plans for the interiors—click through for a first look.
