Hearst Headquarters: Negar Dibaei

The Hearst Tower project involved renovating and expanding the original 6-story 1928 Hearst Headquarters building in New York City. Foster + Partners designed a 46-story tower that incorporated the landmark facade of the original building. Their design preserved the historic facade through a diagrid steel frame that uses less material. The tower's glass and steel facade also reduces energy consumption. The foundation was strengthened to support the new multistory design while keeping the limestone facade intact.

Hearst Headquarters
Architects:
2006 – New York, USA Foster + Partners
BACKGROUND

• The original six-story structure was built in 1928 and


was meant to be the base of a skyscraper expansion.

• The Great Depression and then World War II


postponed these expansion plans.

• In 2001, the Hearst Corporation decided to


consolidate the offices it rents for nearly 2,000
employees in a new 46-story tower.

DESIGN CONCEPT
Preserving New York’s Heritage-- The
Landmark Facade

• An important design specification was the


preservation of the existing landmark facade
and its incorporation into the new tower
design.

• Hearst’s original intention for this building


was to provide a high quality work
environment for his employees

• The building truly celebrates the marriage of


he old and new.

• The first “green” high rise office building to be completed in
New York City, Hearst Tower accurately represents the
talent and intellect that drives Foster and Partners toward
innovative and ground breaking design.

• The building's symmetrically jagged silhouette is easily


recognizable in its surroundings. The diagrid facade
comprised of triangulated steel frame was designed to use
21% less steel than traditional buildings of it's type. Also
impressive is the statistic which states that 90% of the
10,480 tons of steel used is derived from recycled material.

• the glass and steel fascade reduces the heat absorbance of
the building as chemically coated glass prevents suns heat
from entering the building, which a concrete or aluminium
clad structure usually absorbs. This alone cuts the air
conditioning costs of the building and reduces the overall
elec consumption by 25%. Earlier, the structure was a six
storeyed building. Its foundations were not strong enough to
bear the weight of the multistorey tower. So the architect
demolished the floors on the existing structure, leaving only
the limestone clad fascade, to send the columns of the
abovelying tower down below the earth.

• The facade looks sculpted and logical with the receding corners of the
diagonal steel structure, because unlike standard constructions, the
steel girders of the façade run diagonally as opposed to vertically. The
framework of the crystalline-looking building consists of four-storey
mosaic-like triangles which can be made out thanks to stainless steel
dividers. A diagonal network covers the glass façade which appears to
arise from the historical walls.
