North Square part of the original central area of Hampstead Garden Suburb, forming a rectangle with Central Square and South Square.
Raymond Unwin’s 1905 preliminary plan of Hampstead Garden Suburb defined a central area containing churches and public buildings with a formal approach road from the Heath.
By 1908 the design had become formalised with two central churches and The Institute, dedicated to adult learning. The Institute subsequently became Henrietta Barnet School. It was not possible to mirror the houses on the west of North Square with others, due to land ownership issues.
