Tait, the Bishop of London, praised his alterations at St. Mary's, Ealing, as "the transformation of a Georgian monstrosity into the semblance of a Byzantine Basilica". As well as Gothic Revival churches, he designed several country houses and even complete villages, as he did at Hunstanworth in County Durham in 1863. Style Despite his classical training, Teulon's early designs were mostly in imitation of Tudor and Elizabethan styles, and he soon became an enthusiastic follower of the latest developments of the Gothic Revival. He was an enthusiastic user of Polychrome brickwork. His planning was often elaborate: Henry-Russell Hitchcock called his mansion at Elvetham Park in Hampshire "so complex in its composition and so varied in its detailing that it quite defies description". Some of his later work was, however, more restrained: for instance at St Stephen's Church, Rosslyn Hill, Hampstead, (1869–76) the exterior is of purple-brown brick, of subtly varied tones with light stone trimming. The massing of the building is also simpler than in his earlier designs. Death For the last 20 years of his life until his death on 2 May 1873, Teulon lived in one of four Georgian mansions on Hampstead Green which were demolished at the start of the twentieth century to make way for Hampstead General Hospital, which was itself demolished in the 1970s and replaced by The Royal Free Hospital. Opposite his home he designed St Stephen's Church, Rosslyn Hill. He is buried on the west side of Highgate Cemetery, not far from the family vault of his former neighbour on Hampstead Green, Rowland Hill. His great great great nephew, Alan Teulon, published a book on S.S. Teulon in 2009. He was survived by four sons and four daughters.
