The Willis Building in Ipswich, Suffolk, is a Grade I listed office structure completed in 1975 for the insurance company Willis Faber & Dumas (now Willis Towers Watson). Designed by Norman Foster and Wendy Cheesman following the establishment of Foster Associates, the building is widely regarded as a landmark in the development of high-tech architecture. Constructed between 1970 and 1975, it accommodates approximately 1,300 staff across three floors of open-plan offices, exemplifying the modernist spatial innovations characteristic of its era.
