The east façade of the new Northwest Corner Building faces Columbia's original Morningside Heights campus; largely glazed, the elevation clearly showcases the building's diagonally braced structure.
A four-story bridge cantilevers off the new building and connects with the existing Pupin Physics Laboratory next door. Additional bridges on the south face connect to Chandler Laboratories, farther down Broadway.
The façades (including the north and west, this image) incorporate extruded aluminum louvers and clear anodized aluminum panels.
A stair leads to a second-floor café that anchors a four-story glazed atrium with escalators to the library and research elevator core above.
The engineering library has a wood-slat ceiling that again mimics the striations of the etched façade panels. Inset mirrored panels reflect the students working and also reflect daylight to brighten the space.
