After Sir Ebenezer Howard initiated the development of a garden city at a site a mile south of the village of Welwyn in 1920, the Canadian town planner, Louis de Soissons, was asked to prepare a masterplan for the area.

That masterplan envisaged a long boulevard on a north–south axis with a semi-circular green, which would be known as The Campus, at the north end.

The new council offices were designed by Cecil Harry Elsom in the Neo-Georgian style, built in red brick and were officially opened on 6 January 1937.
