Located in the Midtown East neighborhood of Turtle Bay, this project involved combining two separate units to create a duplex three bedroom apartment. The upper unit required a gut renovation to provide a new Master Bedroom suite, including the replacement of an existing Kitchen with a Master Bathroom, remodeling a second bathroom, and adding new closets and cabinetry throughout. An opening was made in the steel floor structure between the units to install a new stair. The lower unit had been renovated recently and only needed work in the Living/Dining area to accommodate the new staircase. Given the long and narrow proportion of the apartment footprint, it was important that the stair be spatially efficient while creating a focal element to unify the apartment. The stair structure takes the concept of a spine beam and splits it into two thin steel plates, which support horizontal plates recessed into the underside of the treads. The wall adjacent to the stair was clad with vertical wood slats to physically connect the two levels and define a double height space. Whitewashed oak flooring runs through both floors, with solid white oak for the stair treads and window countertops. The blackened steel stair structure contrasts with white satin lacquer finishes to the slat wall and built-in cabinetry. On the upper floor, full height electrolytic glass panels bring natural light into the stair hall from the Master Bedroom, while providing privacy when needed. archphoto.com
