Townsend and Lyons restarted their partnership after the war working mostly on war-damage restoration and house alterations. In 1948 they completed Oaklands, a small housing development of four, two-storey, six-apartment blocks set in landscaped grounds in Whitton that was the prototype of their future success.
Span Developments
In 1953, frustrated with a lack of support from developers and funders for their ideas for modern economic housing, Townsend established Bargood Estates, a development company of his own in conjunction with Henry Cushman, an agent for the Alliance Building Society. Townsend resigned from RIBA due to their conflict of interest rules of the time. Although the partnership with Lyons was legally ended, they continued to share the same business premises, the studio offices at Lyons' home, Mill House, East Molesey, maintaining their close collaboration. Townsend and Cushman, acquired land near Ham Common, Ham, London. Working with Lyons as consultant architect they developed Parkleys; 169 flats across fifteen two and three-storey H-plan blocks and a block of six shops and maisonettes. As the project progressed, Townsend and Cushman were joined by Leslie Bilsby, another former Regent Street Polytechnic student, to form Priory Hall Ltd.. In 1957, Bilsby gave up his other business interests and, together, the group formed Span Developments. Townsend was particularly conscious of the need to organise maintenance of the estate following sale. He promoted the concept of a legally constituted Residents' Association, membership of which would be a condition of sale, and which would include covenants that would place mutual obligations on the residents. Span developed 73 schemes comprising 2134 dwellings up to the end of the 1960s. The ambitious New Ash Green project, an entire village, hit substantial financial difficulties, causing Lyons to withdraw and Bilsby and Townsend to resign. Townsend worked independently as a developer for several years thereafter. Bilsby and Townsend reunited in the late 1970s and formed SPAN Environments Ltd working once more with Lyons and Cunningham as consultant architects and Gostling, the builder from New Ash Green, doing the construction. Together they constructed four further developments in Blackheath and New Mallard Place in Teddington. The latter was conceived before Lyons' death in 1980 and completed in 1984, by which time Townsend was in his early 70s.
Death and legacy
Geoffrey Paulson Townsend died in Worthing, West Sussex in August 2002, aged 91. Townsend's focus on the post-sale social and administrative cohesion of the estates SPAN built is credited with the long-term preservation and maintenance of Span's projects.
