An interior build-out of a two-level penthouse unit in a prestigious downtown highrise. The design emphasizes the continuity of space for a loft-like environment. Sliding doors transform the unit into discrete rooms as needed. The material palette reinforces this spatial flow: white concrete floors, touch-latch cabinetry, slip-matched walnut paneling and powder-coated steel counters. Whole-house lighting, audio, video and shade controls are all controllable from an iPhone, Collaboration: Joel Sanders Architect, New York. Photographer: Rien van Rijthoven
