Gaydon hangar at RAF Wittering

The Gaydon hangar at RAF Wittering is a 20th-century aircraft hangar, constructed of reinforced concrete north and south walls, and steel-framed east and west doorways clad with galvanised corrugated steel sheet under a segmentally-arched roof of transverse and longitudinal tubular steel lattice trusses finished with ridged steel sheeting, which was replaced in 1997. The hangar possesses a simple rectangular plan with sliding, full-width doors in the short sides. Ancillary brick office buildings from the 1970s are arranged along the south side, and three steel-framed plant rooms are situated to the north.

The structure is a wide hangar shed with a segmentally-arched roof that descends on the north and south sides to tall concrete and brick side walls featuring upper clerestory glazing. At the east and west ends are steel-framed screen walls terminating in reinforced concrete corner piers. From these piers extend latticed steel gantries, each the width of the seven full-height, overlapping hangar doors, fitted with upper runners. Recessed rails are set into the concrete apron; when the seven doors are fully open, they slide into the gantries. The central door is taller, designed to accommodate the high tail plane of English Electric Canberra B2 and V-force bombers.

The north and south elevations each feature six reinforced concrete bays with clerestory glazing of twenty panes per bay. A long range of single-storey, flat-roofed offices, built in stretcher-bond brick in the 1970s, runs along the south side and are considered not of special interest. The north side contains three full-height steel-framed plant rooms, which have been variously modified and rebuilt since the 1980s and are also not of special interest.

The interior comprises a large, single space with a coated concrete floor and seven triangular lattice tubular steel segmental roof trusses springing from the north and south concrete piers. Thirteen smaller, flat, longitudinal lattice trusses run above them in an east-west direction. Longitudinal triple radiant tube heating pipes, installed between 1984 and 1986, are attached to the underside of the roof trusses. Much of the fenestration on the north side has been bricked up due to the addition of the plant rooms.
