It's been an eventful week for supertall construction in New York City. Central Park Tower became the tallest residential building in the world, eclipsing 432 Park Avenue just blocks away. And now, developer SL Green has announced that its 58-storey skyscraper, One Vanderbilt, has topped out and become Midtown Manhattan's tallest office building.

The construction crew, managed by AECOM Tishman, raised pieces of the spire into place to accomplish the building's full 427-metre height last week. The pace of construction has been abnormally swift—the building's topping-out comes more than three months ahead of schedule. 

The Kohn Pedersen Fox Associates-designed development is composed of four interlocking and tapering components, clad in terracotta tiles that mimic the ceiling of the neighbouring Grand Central Terminal. At ground level, angled cuts in the facade on the south side of the block open up new sightlines to the historic train station. SL Green has committed $220 million to improve the infrastructure within Grand Central, including new staircases, a transit hall, and two new subway entrances.

One Vanderbilt is 59 percent leased by global finance, law and real estate firms. Upon completion, the project will offer tenants a 30,000-square-foot amenity floor with large meeting spaces, a club-style lounge, curated food and an outdoor terrace. An 11,000-square-foot restaurant by chef Daniel Boulud is also in the works.

"Taking its rightful place on New York's iconic skyline, One Vanderbilt will establish a state-of-the-art work environment in New York with unprecedented amenities, including exceptional ceiling heights, incredible views, and direct access to transit networks in the heart of East Midtown," said Marc Holliday, Chairman and Chief Executive Officer of SL Green. "Thanks to our construction partners and their talented, hardworking crews, we're extremely proud that One Vanderbilt has topped out ahead of schedule and under budget, especially given the project’s scale and infrastructural complexity. With the building scheduled to open in less than a year, the next generation of office space in New York is well in sight."
