The Bronx General is an adaptive re-use of a WPA-era post office facility into a mixed-use retail, office and entertainment space. The building was constructed in 1935 and since has served as the primary sorting facility for the Bronx and a vital social hub for the area. Our design concept emerged as a way to maintain the character of the Landmarked building while introducing a new level of connectivity, both physically and symbolically, through the building interior and to the surrounding neighborhood. A series of permeations to the building enclosure inserted at street and terrace levels activate the perimeter, while a continuous internal network of programmed ramps was designed to visually and programmatically connects the layers of program within and deliver additional light to the floor plates. A new lobby entrance at the former loading dock further engages the building at street level and connects visitors to the market and office floors above. Atop the building is a single-level polycarbonate addition serving as an event and entertainment venue. Polycarbonate cladding provides a transmissive and ethereal quality - softly reflect the sky tones and distinguishing itself clearly from the glazed brick cladding the historic host building below.
