Hangar and Annexes

The building is a hangar and annexes, constructed with a riveted steel girder frame measuring 162 feet 7 inches by 121 feet 4 inches (49.53 meters by 36.96 meters). It features a saw-tooth ridged roof with half-bays at each end and five additional half-bays in between. The structure includes concrete-encased steel piers that rise to a height of 59 feet 9 inches (18.21 meters) at the angles and up to each gable apex, with steel uprights positioned between them. The concrete infill reaches a height of 30 feet (9.14 meters), while the upper half is clad in corrugated iron. A steel gantry runs around the building below the gables. The eastern front has a clear opening measuring 160 feet by 40 feet (48.76 meters by 12.19 meters), featuring six large rolling steel doors that have spaced steel plating to accommodate gravel infill for protection against bomb fragments. On the southern side, there is a rendered and painted two-storey flat-roofed range, along with single-storey ranges to the west and north.
