Developer Silverstein Properties has topped out the $1.6bn 4 World Trade Center in New York City, US, with the erection of the final beam for the building’s steel skeleton.

As part of topping out of the building, the eight-tonne beam was placed atop the 72-storey tower, raising its height up to 977ft.

Designed by Japanese architect Fumihiko Maki, the tower has a floor space of 2.3 million ft² and will be the first office building to open on the 16-acre World Trade Center Site.

Maki said: "The design of the tower at 150 Greenwich has two fundamental elements – a minimalist tower that achieves an appropriate presence, quiet but with dignity, and a podium that becomes a catalyst for activating the surrounding urban streetscape as part of the revitalisation of lower Manhattan."

From a distance the building has been designed to look like an angular structure at the top and present a spiral composition formed by the four towers at the site.

The podium base of the tower consists of the ground floor, two levels above grade and two retail levels below grade which will be used for restaurants, shops and boutiques.

The tower portion of the building will house office spaces in two separate shaped floor plates.

The lower and mid-rise sections of the tower from floors 7 to 46 will include a rentable floor plate size of 44,000ft² in the shape of a parallelogram.

The high-rise section of the tower, spanning from the 48th to the 63rd floor, will feature a trapezoidal floor plate to offer 34,000ft² of rentable space.

The tower has been designed to achieve a LEED Gold certification from the US Green Building Council.

After completion of the tower, the Port Authority of New York & New Jersey’s headquarters will occupy about a quarter of the office space and the City of New York will occupy 600,000ft²; the remaining space will be reserved for Silverstein Properties’ commercial tenants.

Construction of the tower began in 2008 and it is scheduled to open in autumn 2013.
