1080 5th Avenue
Constructed 2005-2007
Architect: Hillier Group; Principal in charge: Peter Schubert; Project Architect: Georg Windeck Structural Engineer: WSNY; Project Engineer: Wilfried Laufs
This project was the combination of several apartments in a building on 5th Ave into one residence. Key component was a staircase to connect the floors on the façade of the building within the setback portion of the top floors. The staircase is housed in an elliptical glass enclosure facing the Guggenheim Museum and Central Park. Its shape is defined by the curvature of most comfortable travel possible within the smallest space affordable, in order to minimize the zoning encroachment. The glass enclosure consists of curved load-bearing insulation glass that stands by itself without any metal support over the full height of two floors. It is the tallest structure of its kind that has been built to date.
