Council house design developed in the early decades of the 20th century. The earliest council house in Oxford, was indistinguishable from standard Victorian terraced housing. The 20th century brought new materials and a new confidence, and radical ideas for housing design, such as round concrete houses, were considered though not executed. Other designs, like those on the south side of Cumberland Road, and the houses on the White City estate, reflected the influence of contemporary architectural ideas, such as the Arts and Crafts and Garden City movements. However, by the 1930s council house design had arrived at its own more urban idiom that expressed the ideals that councils wanted to impart: economy, order and unity. The Georgian style was taken as a suitable model.
