Team 4 was a British architectural firm, established in 1963 by architecture graduates Su Brumwell, Wendy Cheesman, Norman Foster and Richard Rogers. Friction emerged within the firm, and by June 1967, Foster and Rogers decided to dissolve the firm.

Norman Robert Foster, Baron Foster of Thames Bank, is an English architect and designer. Closely associated with the development of high-tech architecture, Foster is recognised as a key figure in British modernist architecture. His architectural practice Foster + Partners, first founded in 1967 as Foster Associates, is the largest in the United Kingdom, and maintains offices internationally. He is the president of the Norman Foster Foundation, created to 'promote interdisciplinary thinking and research to help new generations of architects, designers and urbanists to anticipate the future'. The foundation, which opened in June 2017, is based in Madrid and operates globally. Foster was awarded the Pritzker Prize in 1999.
