The development company Span built 30 housing estates across the UK between 1948 and 1984. In his book The Spirit of Span Housing, James Strike summarises: “Span housing was the inspiration of two young men, who, during the 1930s, met as architectural students at the Regent Street Polytechnic. Eric Lyons and Geoffrey Townsend both had a keen interest in modern architecture… They believed that there was a market for well-designed houses in carefully designed landscapes for the sort of people who recognised good design when they saw it – and they were right.”

In 2006, Span housing was the subject of an exhibition at the RIBA, and the accompanying book, entitled Eric Lyons & Span (ed. Barbara Simms), gives a comprehensive survey of its history. “The work of the architect Eric Lyons,” it states, “is as well-loved now as it was vibrantly successful when first constructed. Built almost entirely for Span Developments, its mission was to provide an affordable environment ‘that gave people a lift’.”

The Cator Estate is made up of 282 acres of private roads and features architectural jewels from across the ages; from classical villas built at its inception in the late Georgian period, to the modernism of Lyons’s Span Housing. Graham Morrison of Allies & Morrison Architects, who bought a Span House in the early 1980s, describes the joy of living on the Cator Estate: “I find it hard to imagine a more pleasant and safe place, so close to the city, in which to bring up young children. A shared garden made the making of friends easy and a sensible management structure helped to ensure the maintenance of not only the buildings and gardens but also the aims of the community.”
