Over the past 20 years our buildings have made a significant difference to their surroundings. The practice has revitalized architectural landmarks, such as Michelin House, Butlers Wharf and Bluebird Garage, produced the greenest building of its time, the Longman Headquarters in Harlow, and designed new developments for City Lofts all over Britain. We have recently completed work on Roppongi Hills, a new 11-hectare urban quarter in the heart of Tokyo. In quality of design, no less than in richness and diversity of ideas, each building serves to enhance its location.
