Kohn Pedersen Fox designed One Vanderbilt and Summit One Vanderbilt for developer SL Green Realty. The attraction is split into three parts called Ascent, Levitation and Summit.
Ascent is a glass elevator complete with a transparent floor that will take visitors up the outside of the supertall skyscraper to a height of 1,210 feet (369 metres). Snøhetta has designed interiors for the attraction
Glass boxes that form part of an attraction called Levitation will protrude from the side of the building, allowing guests to look down over the city from 1,063 feet (324 metres).
The observation deck called Summit and will feature high glass perimeter walls and an open-air bar.

In total, the Summit One Vanderbilt attraction encompasses 65,000 square feet (6,038 metres) over four levels.
