Having worked for Walter Gropius and Maxwell Fry, Eric Lyons (1912-1980) co-founded the development company Span in 1948, along with Geoffrey Townsend and Leslie Bilsby. Lyons’s Span houses are all about space and light, and blurring the edges between outside and indoor space. He paid great attention to the surrounding landscape, designing and building properties around existing splendid mature trees and creating communal areas that encourage residents to mix. An early Span publication summarises the origin of the name: “It spans the gap between the suburban monotony of the typical ‘spec building’ and the architecturally designed individually built residence.” Outside of his Span work, Lyons carried out a number of other schemes, including public housing for World’s End in Chelsea. He was appointed President of the RIBA in the 1970s.
