The kitchen is minimalist, equipped with built-in appliances and storage. A wooden table with transparent chairs for six is an open invite to guests.

The attention to detail on this triplex penthouse is unusual, thanks to a successful collaboration with a client interested in unique solutions without compromise. This meant traveling with architect Wayne Turrett to a remote quarry in the Swiss alps to handpick 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.

This penthouse is breathtaking, really beautiful and elegant. The wide spaces, bright colors, stone and wood combinations are amazing and create a modern and cozy place.
