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.
Soutar's older brother, Archibald Stuart Soutar (1879–1951), was also an architect. 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. John Soutar had joined the department in 1901 following an apprenticeship with Thomas Martin Cappon.
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). This competition was assessed by Raymond Unwin, who subsequently commissioned them to work on Hampstead Garden Suburb in 1913–14. 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. John Soutar then became sole architect to the Hampstead Garden Suburb Trust, maintaining an office at Wyldes, and designing over 100 houses and other buildings, including parts of the institute (today part of Henrietta Barnett School). 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.
John Soutar died on 27 February 1951 at Fairport, Hampstead Garden Suburb.
Sir Edwin Landseer Lutyens was an English architect known for imaginatively adapting traditional architectural styles to the requirements of his era. He designed many English country houses, war memorials and public buildings. In his biography, the writer Christopher Hussey wrote, "In his lifetime (Lutyens) was widely held to be our greatest architect since Wren if not, as many maintained, his superior". The architectural historian Gavin Stamp described him as "surely the greatest British architect of the twentieth century".

Richard Norman Shaw RA, also known as Norman Shaw, was a British architect who worked from the 1870s to the 1900s, known for his country houses and for commercial buildings.

The garden city movement was a 20th century urban planning movement promoting satellite communities surrounding the central city and separated with greenbelts. These Garden Cities would contain proportionate areas of residences, industry, and agriculture. Ebenezer Howard first posited the idea in 1898 as a way to capture the primary benefits of the countryside and the city while avoiding the disadvantages presented by both. In the early 20th century, Letchworth, Brentham Garden Suburb, and Welwyn Garden City were built in or near London according to Howard's concept and many other garden cities inspired by his model have since been built all over the world.

The object of the new suburb, which was built on land belonging to Gidea Hall, then occupied by the Liberal politician Herbert Raphael, was, according to his parliamentary colleague John Burns, to "provide families with a well-built, modern home regardless of class or status" and "to bring the towns into the country and the country into the towns".
