The pyramid shaped tower block or "tetrahedron", designed by the Danish architecture firm Bjarke Ingels Group (BIG), rises 467 ft (142 m) and is 35-stories tall.

[4][5] According to The New York Times, the name was chosen "because the southbound West Side Highway slopes down as drivers enter the city, right at the spot where the building is situated", serving as an entrance to Manhattan "via 57th".

[7] With its angular balconies around an integrated green plaza, the block connects with the waterfront and Hudson River Park, taking full account of the surroundings while providing views with little traffic noise.

[9] The northern façade of the building features a number of balconies skewed at a 45-degree angle, a pattern employed in Ingels's previous works, such as the VM Houses in the Ørestad section of Copenhagen.

[7] The theater closed in August 2020 following nearly three years of operation after struggling to attract moviegoers, in part due to the location's distance from public transit.
