Hearst Tower revives a dream from the 1920s, when publishing magnate William Randolph Hearst envisaged Columbus Circle as a new media quarter in Manhattan. Hearst commissioned a six-storey Art Deco block on Eighth Avenue, anticipating that it would eventually form the base for a tower, though no such scheme was ever advanced. Echoing an approach developed in the Reichstag and the Great Court at the British Museum, the challenge in designing such a tower at seventy years remove was to establish a creative dialogue between old and new.
The new tower rises above the old building to a height of forty-four-storeys, linked on the outside by a skirt of glazing that encourages an impression of the tower floating weightlessly above the base. At the base of the tower, the main spatial event is a lobby that occupies the entire floor plate of the old building and rises up through six floors. Like a bustling town square, this dramatic space provides access to all parts of the building. It incorporates the main elevator lobby, the Hearst staff cafeteria and auditorium, and mezzanine levels for meetings and special functions. Structurally, the tower has a triangulated 'diagrid' form - a highly efficient solution that uses 20 per cent less steel than a conventionally framed structure. With the corners cut back between the diagonals, it creates a distinctive facetted silhouette on the Manhattan skyline.
The building is also significant in environmental terms. It was built using 85 per cent recycled steel, its heating and air-conditioning equipment utilises outside air for cooling and ventilation for nine months of the year, and it consumes 25 per cent less energy than an equivalent office building that complies minimally with the respective state and city codes. As a result, it was the first office building in Manhattan to achieve a gold rating under the US Green Building Council's Leadership in Energy and Environmental Design (LEED) programme. As a company, Hearst places a high value on the quality of the working environment - something it believes will become increasingly important to its staff in the future - and it is hoped that Hearst's experience may herald the construction of more environmentally sensitive buildings in the city.
The building envelope was designed to limit glare from low angle sun during the early morning and evenings.
The massing was predetermined by the footprint of the existing Hearst building. The design of the tower, sought to protect the existing podium, whilst extending the building with a distinctive new tower.
The design included an upgrade to the local subway station, and reinstated an entrance within the building, giving employees direct access to public transport.
The diagrid structure uses 20 per cent less steel than a conventionally framed structure, and it was built using 85 per cent recycled steel. Locally sourced materials are used throughout.
The design ensured that all existing trees on site were protected, and to ensure their long term vitality, they are now irrigated through the rainwater harvesting system.
The design preserved the façade of the existing structure and establishes a creative dialogue between the old and new. The forty-two-storey tower rises above the old building and has resulted in an award winning addition to the New York Sky Line.
