Seymour was living aboard a Dutch sailing smack when he married Sally Medworth, an Australian potter and artist in 1954. In this they travelled around the waterways and rivers of England, journeys later described in "Sailing through England". As their first daughter grew older they felt that a land-base would be more suitable. They leased two isolated cottages on of land near Orford in Suffolk. These 5 acres are still called Seymour's Bit by the current owner. The manner in which they developed self-sufficiency on this smallholding is recounted in "The Fat of the Land" (1961). At the end of the 1960s, Seymour, along with other radical voices like Herbert Read, Edward Goldsmith, Leopold Kohr and Fritz Schumacher, provided a stream of articles for the journal "Resurgence" edited from 1966 to 1970 by John Papworth.
