73rd Street Penthouse located in New York, and designed by Turret Collaborative Architects.

“The attention to detail on this triplex penthouse is unusually high -even by our standards- thanks to a successful collaboration with a client interested in unique solutions without compromise. This meant traveling with Wayne to a remote quarry in the Swiss alps to hand pick the stone for the double-height wall around the 15-foot-wide fireplace. It meant creating a seamless walk-in soaking tub within an all glass room, made alternately opaque for privacy or perfectly clear at the flip of a switch. And it meant a soaring, meandering triple-height stair with laser-cut steel supports and translucent resin treads, cantilevering in places like stiff diving boards and bridging at higher levels, casting warm, orange-tinted shadows through the halls. We’re very excited to have completed this exceptionally challenging design, which richly rewards the owner’s high expectations.” [turettarch.com]
