The Type D aircraft shed (often called the "D Type") was designed in 1936 and built primarily at aircraft storage units.
They were built of reinforced concrete columns that supported concrete arched ribs forming the roof. The walls are solid 14in thick reinforced concrete. The doors consist of six steel leaves, opening into concrete door gantries at each side. Early examples (e.g. Kemble) had more glazing than later variants, some of which had no glazing at all (e.g. Wroughton). Typical dimensions are a length of 300ft, a span of 150ft and a clear door height of 30ft 9in.
Remaining examples can be seen at Brize Norton, Hullavington, Kemble, Little Rissington, Silloth and Wroughton.
