The building has a triangular observation deck jutting out from the 101st floor. This observation deck, at 1,100 feet, will be the highest outdoor observation deck in the Western Hemisphere, (the Empire State Building's 102 floor observation deck, at 1,224 feet, is enclosed). The view will offer new skyline views to the south and east of Manhattan, the surrounding boroughs, and New Jersey.
The groundbreaking ceremony took place on December 4, 2012. Early construction work focused on building a platform to cover much of the Eastern Rail Yard, for much of Phase 1 to sit upon. The platform is rested on caissons, that are drilled underground. On December 12, 2013, it was announced that Tutor Perini Building Corp. was awarded a $510 million contract to build the platform.
In mid-2015, Related received a $690 million loan from Bank of America, Wells Fargo, and CIBC which allowed construction to start. By January 2016, the structure's first few aboveground floors were already complete. Construction of the observation deck at the top of the tower began in April 2018. The observation deck was nearly complete by mid-2018.
Kohn Pedersen Fox was chosen for the design of the building. Originally planned to be 1,337 feet (408 m) tall, the building was later downsized to 1,268 feet (386 m) tall, making it still the development's tallest building. WarnerMedia's space features amenities including a cafeteria, a fitness center, a two-level auditorium and cinema and an outdoor deck.
The building will feature a 80-foot (24 m) observation deck that juts into the air. The building's lobby will contain artwork by Spanish artist Jaume Plensa consisting of 11 stainless steel spheres hanging from the ceiling, meant to represent global unity and cultural diversity.
