Which British architectural firm designed the Barbican Estate?

The British architectural firm that designed the Barbican Estate was Chamberlin, Powell and Bon.

The partnership consisted of Peter “Joe” Chamberlin, Geoffry Powell and Christoph Bon. It was formed in 1952 after Powell won the competition for the nearby Golden Lane Estate, a project that helped establish the architects’ reputation for innovative postwar housing.

The Barbican was developed on a bomb-damaged area of the City of London. Construction took place from 1965 to 1976, producing a large residential complex of towers, terrace blocks, maisonettes, gardens, lakes and elevated pedestrian walkways. The firm also designed the associated Barbican Centre, although it opened in 1982, after the housing estate was substantially complete.

A common mix-up is Arup, which acted as structural and civil engineer rather than architectural designer. Rogers Stirk Harbour and Foster + Partners are prominent British practices, but neither designed the Barbican. The estate is now a Grade II listed example of British Brutalism.
