Kenneth Campbell, who headed Britain's largest council housing design department, has died aged 92.
From 1960 to 1974, Campbell served as housing architect to the London council and its successor, the Greater London Council.

Campbell's section of the GLC department of architecture pioneered radical forms of public-sector housing, often employing some of the brightest architects. The department employed more than 250 staff at its peak.

High-density GLC estates, such as the Canada estate in Bermondsey, south London, were designed by Campbell's branch with bold combinations of high- and low-rise blocks. After the collapse of Ronan Point in east London in 1968 the branch turned its attention to low-rise high-density forms. It also experimented in industrialised building, including a three-storey block in Stoke Newington built using metal containers.

Unfailingly affable and approachable, Campbell was a natural committee man. He served on the RIBA council for 22 years, as vice-president for two years.

Like several senior architects at London council he was also a member of the then Communist Party of Great Britain and turned down a CBE.
