text: The Willis Building is a glass-clad building owned by Willis. Designed by Norman Foster, the building dates from 1974, when it was known as the Willis Faber & Dumas building. It became the youngest grade I listed building in Britain in 1991, being at the time one of only two listed buildings to be less than thirty years old.
  In September 1993, Ipswich and Arras, Nord Pas-de-Calais, France, became twin towns, and a square in the new Buttermarket development was named Arras Square to mark the relationship.
  Ipswich formerly had a municipal airport to the south-east of the town, which was opened in 1929 by the Ipswich Corporation. The airport was controversially closed in 1996. The site was redeveloped for housing as the Ravenswood estate.
  21st century
  Ipswich has experienced a building boom in the early part of the 21st century. Construction has mainly concentrated around the former industrial dock which is now known as the Ipswich Waterfront. Regeneration to the area has made it a hub of culture in Ipswich, the area boasts fine dining restaurants, a boutique hotel, and the new regional university, the University of Suffolk. The new high rise buildings of the Regatta Quay development has topped the list of the tallest buildings in Ipswich. The mixed-use high rise building, the The Mill, is currently the tallest building in Suffolk.
