3 World Trade Center

New York City

The masterplan for the World Trade Center (WTC) site in Manhattan, New York, was designed by Studio Daniel Libeskind and focuses on the 9/11 memorial –two reflecting pools in the centre of the site.

The architectural concept for 3 World Trade Center was realised as part of the wider context of the WTC masterplan, and represents a resolution of the varying requirements of the New York Port Authority and the client, Silverstein Properties.

3 World Trade Center is on a site bounded by Greenwich Street to the west, Church Street to the east, Dey Street to the north and Cortlandt Street to the south. It is opposite the WTC Memorial and Cultural Center, and at the heart of the cluster of buildings which surround the memorial. The brief for 3 World Trade Center outlined the building’s function as the site’s commercial core. The tower had to address the issue of balancing retail and office space, while also complementing and acknowledging the WTC memorial.

The building has an orthogonal relationship to the main space between the proposed memorial water pools. To complement this relationship, the central zone of the building has been reduced in mass as it rises towards the sky. The effect is a stepped profile which accentuates the building’s verticality, relating to the memorial site and is sympathetic to the height and positions of the neighbouring buildings. Antennae emphasise the height and slender profile of the building both in the local context, and as part of the Manhattan skyline.

The design includes five trading floors, 54 office floors (totalling 2.1 million sq ft) and five retail levels, as well as eight mechanical floors which serve the trading and office floors, 37 passenger lifts and two principal stairwells. The lower part of the building –the ‘podium building’ – contains the tower’s retail element and the trading floors. The upper levels of the tower hold the office spaces. ‘Live’, active façades, at street level, enable the free-flowing movement of shoppers. There are two below-grade retail levels and three retail levels above the ground floor, served by two lifts and four stairwells.

To maximise sustainability in terms of the building’s day-to-day functioning, similar ‘green design’ features as those included in the design of 7 World Trade Center have been incorporated. The design team has ensured that energy use and costs are significantly reduced compared to typical Manhattan office buildings.

The project obtained LEED Gold Certification from the U.S. Green Buildings Council for Building Design & Construction Core & Shell.

This office tower – with retail at its base – provides an important new addition to the New York skyline and creates a strong relationship with the adjoining World Trade Center memorial gardens

The proposal for No. 33 Park Row describes a boutique residential scheme in Lower Manhattan, made up of 30 apartments with four levels of commercial space at the base of the building. The proposed tower will rise 23-storeys addressing Park Row’s early 20th Century ‘skyscrapers’ and giving excellent views north across City Hall Park.

Located at the corner of Beekman Street and Park Row the building steps up to provide a bridge between the ten storey properties on Beekman and those on Park Row. The primary core acts as a unifying vertical structural element, extending above the roof levels to provide roof top plant. The kite shaped plan is set out on the diagonal and the building facades follow this arrangement to place a strong visual emphasis on the corner.

The building’s structural and internal apartment arrangement is expressed in two-storey façade modules.

The primary building arrangement facing North mitigates overheating through solar gain, and loggias serve to provide shading to residential facades.

Depth and materiality of the facades give privacy for residents and this is achieved through a series of deep, articulated loggias, which pay homage to the early 20th century New York architectural context and give the building its strong identity.

Made up of fabricated metal sections and concrete, the hue of the patinated copper side screens is varied to differentiate the commercial and residential levels. The flank walls are clad in brick and act as braced bays, stabilising the tower and further directing views north to the park.
