 The Doughnut is divided into three separate four-storey structures, identical in design and connected at the top and bottom. With a total floor area of 140,000 square metres (1,500,000 sq ft), the building contains two circular blocks, internally divided by a "street" covered in glass. Construction materials were primarily steel, aluminium, and stone, particularly granite and local limestone from the Cotswolds; designers incorporated recycled materials in the steelwork and the construction of desks. The design of the Doughnut was subsequently nominated for an award to "highlight improvements to the built and landscaped environment" given by Cheltenham's Civic Society.
