4 World Trade Center

New York City, New York, USA

Clad in iridescent glass, 4 World Trade Center is a dignified tower that reflects the surrounding city and sky, with an appearance that changes depending on the weather, light and time of day.

Designed to create a quiet sculptural effect, the building’s exterior reduces its visual bulk and complements the more prominent buildings on the site. The structure belongs to a group of buildings following the ‘Memory Foundations’ redevelopment master plan, and is one of five skyscrapers that form a spiral composition around the National September 11 Memorial Park.

The concept

4 World Trade Center stands 72 storeys tall, reaching a height of 298m and providing 213,700 sqm of office and retail space. The building has two distinct floor plates, with the low and mid-rise sections configured in a parallelogram, topped by a trapezoid high-rise section.

What did we do?

We created façade for over 65,000 sqm of custom-unitised curtain wall. This included high-span steel, aluminium shopfront entrances, revolving doors, balance doors, and custom extruded aluminium vertical storm-proof louvres.
