PS 50 Manhattan was designed by Conklin & Rossant Architects in 1973, and completed in 1975. The building enclosure is comprised of ribbed CMU walls and architecturally exposed structural concrete slab edges and stair enclosures.
PS 50 Manhattan’s quadrate-shaped plan consists of 4 floors and has an additional one-story mechanical bulkhead that runs diagonally, from corner to corner, across the roof. Nelligan White investigated two options for the restoration of the exterior masonry. One was a terra cotta rain screen cladding over existing CMU backup, while the other was alternate pinning of the existing CMU exterior with the replacement of two courses of CMU at the top and bottom of the concrete spandrels to accommodate flashing and weeps. Nelligan White recommended proceeding with the terra cotta rain screen option as a redesign of the building envelope that provides greater insulation, high performance, and a more cost-effective design.
Nelligan White Architects also designed a modern greenhouse facility within PS 50 which facilitates teaching urban food production. It is another piece of the school’s framework and acts as infill on a previously unused second-story roof.
