Aircraft Hangar, Single GS Type (16U)

This is an aircraft hangar (General Service Shed), built around 1917. Constructed of red and brown brick with softwood roof trusses and corrugated iron roofing, it also features metal-framed windows with concrete lintels. The hangar is a single-span rectangular structure, approximately oriented east/west, with single-storey brick workshops attached to each side.

The west end is largely bricked in, while the east end is clad with timber boarding, both incorporating inserted doorways. Segmental gables sit above eaves cornices on each end elevation. Tall brick piers at each corner previously supported sliding hangar doors. The side walls feature wide upper windows, each with 12 panes, alternating with 15 raking buttresses rendered in cement. Workshop annexes, built of brick with pitched roofs and casement windows, are attached to the south-east flank (3 bays) and the north-west flank (7 bays), with aluminium casements on the south-east side.

Inside, 15 softwood Belfast trusses span the interior, supporting the curved roof and creating 17 bays. These trusses are formed of a bow-curved upper chord with a tie-beam, connected by close-mesh, criss-cross lattice bars. Horizontal timber bracing runs between the trusses. The tie-beams and bow chords are constructed of sections of half-lapped timbers bolted together, anchored with gusset boards and knee braces, and secured to wall plates with angled bracing struts carried on three-coursed brick corbels. Vertical X-bracing is present between bays, along with longitudinal horizontal bracing fixed to the tie-beams with brackets. Late 20th-century internal fittings and partitioning are not of special architectural or historic interest and are excluded from the listing. Door openings provide access to the workshop annexes on either side.
