John Carrick Stuart Soutar (1881 – 27 February 1951) was a Scottish-born architect, and is particularly associated with the design of buildings in Hampstead Garden Suburb in north London.
Both were admitted LRIBA on 20 March 1911, proposed by William Edward Riley, Arthur Alfred Carder and James Maxwell Scott, of the London County Council architects department.
The Soutar brothers started in independent practice after winning a competition for the layout of Ruislip Manor Estate (on land owned by King's College, Cambridge).
In December 1914, after Unwin was appointed to the Local Government Board, George Lister Sutcliffe took over as consultant architect for the Suburb, but became seriously ill the following year before dying in September 1915.
His contribution to the Suburb was applauded by architectural critic and author Christopher Hussey in Country Life magazine: The Soutars were also architects for the Knebworth Garden Village development,[2] and designed mainly in a late Stuart idiom, influenced by Riley and Sir Edwin Lutyens, who continued to work at Hampstead.
