One High Line

ZONING — The zoning regulations of NYC require a 60-85 ft podium with two independent towers. Given the site is a full city block, both city and river views are achievable with a simple massing of two towers inside the zoning envelope.

TOWER CUTS TO AVOID OVERLOOKING — A perpendicular plane running southwest to northeast slices through the two towers to create an initial separation between the volumes. This allows for the east tower and the west tower to have both city and water views.

BASE SETBACK FROM NEIGHBOR — The towers must respond to the warehouse building located to the south. The base of the towers is set back to create separation. This rotation offsets the loss of area at the base and is also a way of transferring the square footage to a location that can achieve better views.

ROOF SETBACK FROM NEIGHBOR ON SOUTH — 1HL must also set back from a proposed 250 ft tower to the north.

RULED CORNERS — Two corners on each tower are carved away, which creates additional separation between the residential units, helps reduce the overall volume, and emphasizes the movement of the towers as they rise.

PODIUM BRIDGES — To allow for continuous circulation in the podium as well as a through block connection, independent bridge elements are added between the podium volumes. These double height spaces contain unique programmatic elements.

STEPPING, PUNCHED WINDOW OPENINGS — Inspired by the punched windows in the historic warehouses of Chelsea, the façade is designed as a stone volume with punched openings spanning between sloped columns.
