225 East 39th Street
The Prism Tower is a glass phoenix rising from traditional square apartment buildings. It’s this geometry that breaks the phalanx of typical apartment buildings along the avenue. While it might appear that is was a relatively simple glass wall design, several facades of the building have an inclination angle between 10 degrees up to 60 degrees. Rather than stepping back the mass to comply with zoning laws intended to bring light down to the street, the design simply inclined the leading edges of the prisms to open a path of travel for sunlight. Instead of using terraced setbacks to respond to code, the design uses fragmented and angled façades.
