Willis Building (Ipswich)
- For the Willis Building in London, also designed by Norman Foster, see Willis Building (London)
The Willis building (originally the Willis Corroon Headquarters) in Ipswich, England, is one of the earliest buildings designed by Norman Foster after establishing Foster Associates. Constructed between 1970 and 1975 for the insurance firm now known as Willis Group Holdings, it is now seen as a landmark in the development of the 'high tech' architectural style. The building houses some 1,300 office staff in open plan offices spread over three floors.
The bulbous floorplan of the office block reflects the layout of the available site in the centre of Ipswich, which is sandwiched between several road junctions and the Grade I listed Unitarian Meeting House, one of Ipswich's oldest surviving buildings. Thus two of the town's Grade I listed buildings stand side by side.
The centre of the building is constructed from a grid of concrete pillars, 14 m (46 ft) apart, supporting cantilevered concrete slab floors. The exterior is clad in 890 dark smoked glass curtain wall. The use of dark glass, a curtain wall and lack of right angle corners mirrors the art deco Express Building in Manchester - one of Norman Foster's favourite buildings. The central escalator well leads up to a rooftop staff restaurant surrounded by a rooftop garden (360 panorama).
Originally there was also a swimming pool for employees to enjoy during their lunch break. This has now been covered up (not filled in due to it being a listed building) and the space is used for more offices. The swimming pool can be seen underneath the false floor.
