The two new buildings for the Henrietta Barnett School are located in the centre of the Hampstead Garden Suburb and are the first new public buildings on the site for over 60 years.

The new buildings house the Art, DT, Drama and Music departments. They have also been designed with the flexibility to serve as general teaching classrooms in future. The buildings are notable for their form and materials which were carefully designed to complement the existing school building, two churches and residential buildings, all designed by Lutyens.

The red brickwork walls were constructed in Flemish bond using lime-based mortar, with exposed precast slabs at first floor level and a timber-framed roof with matching tiles used typically in the suburb.
