Between 1954 and 1968 Peter Chamberlin, Geoffry Powell and Christoph Bon drew up four distinct schemes, which they continued to modify even after the build started in 1965. Their intention was to create a residential precinct which would allow people to live “both conveniently and with pleasure”. Their mission would include a quiet pedestrian space which would be “uninterrupted by road traffic” and where people would be able to “move about freely enjoying constantly changing perspectives of terraces, lawns, trees and flowers” and seeing “the new buildings reflected in the ornamental lake.” Their vision came to life in the Barbican Estate.

Apartments have individual balconies which overlook verdant landscaped squares and a lake with fountains. The buildings are isolated from the hubbub of the city and accessed by a pedestrian walkway raised above street level. The residential towers are three of London’s tallest. Designing buildings of this height required close collaboration with engineers especially Ove Arup, who were themselves newly founded in 1946, and were increasingly collaborating on complex projects with avant-garde practitioners of the built world. The towers gave a “dramatic contrast to the otherwise horizontal treatment of the buildings” and have become an iconic part of London’s skyline.

In September 2001, Tessa Blackstone, Minister for the Arts, announced that the Barbican Estate was to be Grade II-listed for its special architectural and historical interest. The complex represents a utopian ideal for inner-city living, with its integrated schools, shops, restaurants, theatres and cinemas. It is also one of the most extensive examples of the Brutalist style associated with the honest and raw use of materials.

Queen Elizabeth, after declaring the Barbican open to the public on its completion in 1982 described it as “one of the modern wonders of the world”.
