Edge / 30 Hudson Yards

Edge, the highest outdoor observation deck in the Western Hemisphere, offers visitors 360-degree views from the KPF-designed 30 Hudson Yards office tower.

Rising 1,100 feet above street level, Edge boasts a height 50 feet taller than the Empire State Building’s observation deck. Unlike most sky decks that rest on building setbacks, Edge is a massive triangular platform that cantilevers 80 feet from the 100th floor of the tower, providing an outdoor viewing area of 7,500 square feet with unobstructed views of the city skyline and Hudson Yards below.

Clad in triangular stainless steel panels, the underside of the observation deck creates a vibrant and dynamically reflective focal point, identifiable on the skyline and from street level.

The team selected a bright annealed stainless steel from Finland with an embossed “linen” finish for its reflective qualities. Even the slightest deviations in the highly reflective material surface can be obvious, so each panel was carefully reviewed for flatness and consistency.

The annealed, stainless steel plates sourced from Finland were sent to Italy for review and preassembly. After alignment checks, the sections were shipped to New York. Final image courtesy of Timothy Schenck.

Edge’s platform is made up of 15 sections, which individually range in weight between 35,000 and 100,000 pounds. Each section was pre-assembled at the factory in Italy to ensure proper alignment and fit. Once uniformity was certain for the platform as a whole, the 15 sections were taken apart and shipped to site.

Once at Hudson Yards, the sections were carefully lifted and bolted precisely into place, sometimes requiring two cranes to lift them simultaneously. By pre-assembling the sections off-site originally, construction on the observation deck was able to proceed extremely quickly.

A 9-foot-tall, angled, mullion-free glass wall encloses the deck, allowing visitors to be surrounded by only glass, air and sky as they lean out into the skyline, while the triangular glass floor gives a one-of-a-kind perspective on the neighborhood below. The impressive panoramic views provide prime vantage points over Manhattan with the Hudson and East River on either side.
