The Willis Building

Ipswich, UK

The AET Flexible Space system was specified by FC Foremans as a solution to overcome English Heritage planning restrictions.

Total Area

21,255 sq m

System
AET Flexible Space CAM-V Under Floor Supply, High Level Return Air

1999 Refurbishment

The Willis Building in Ipswich originally constructed in 1974 and credited with listed status in 1991 undertook extensive refurbishment in 1999 including the installation of under floor air conditioning to create additional office space

The AET Flexible Space system was specified by FC Foremans as a solution to overcome English Heritage planning restrictions and limitations associated with ceiling based air conditioning systems.  The installation of a false ceiling was considered undesirable and studies demonstrated that perimeter air conditioning was impractical

The original construction included an indoor swimming pool, however it was decided to convert this area into offices during the refurbishment.  A purpose built removable plug was fitted within the pool and this 1250 sq m area was covered with an adjustable height raised floor creating a plenum which is now used as the ventilation zone for the air conditioning supply

AET also developed a special glass access floor tile to surround and highlight the edge of the pool below in line with English Heritages requirements
