This impetus for this renovation was to create more space for a growing family. The client wanted to add a nursery to this one bedroom duplex in time for the arrival of their new baby. As the apartment existed there was a large double height space at the entry which housed an extremely steep stair to the mezzanine bedroom. In order to expand the space in the mezzanine the floor was extended at the entry getting rid of the double height space and thus necessitating the moving of the stair. A new open stair was created along the wall of the main living space up to the loft. This stair was built out flush with some existing built-ins, housing storage below. Oak treads and risers create a continuous ribbon up to the mezzanine with a blackened steel handrail with glass infill on one side. A small bump out in the wall near the landing informed the design of the last three treads which cantilever beyond the wall below. In the expanded space of the mezzanine, a large master closet and nursery were added. The closet and mezzanine are separated from the bedroom by floor to ceiling etched glass and blackened steel panels. The panel at the closet pivots to allow entry to the closet. At the nursery the three panels slide, stack and pivot so they are flat against the wall completely opening the nursery to the bedroom. The kitchen which is on the lower level was also renovated so that it opens into the living room by replacing the wall with new base cabinetry and counters.
