Building 42, Hooton Park Aerodrome

Building 42 at Hooton Park Aerodrome is a workshop constructed in 1917 for the Royal Flying Corps. The building features rendered brick walls and a gabled roof made of grey resin and fibre-glass, supported by timber lattice Belfast trusses, with black plastic rainwater goods.

The workshop has a single-storey rectangular plan. Its exterior consists of rendered half-brick thick walls laid in stretcher bond, reinforced by brick piers topped with tile copings. The walls are punctuated by 10-pane galvanised steel windows with red tile cills, each window featuring a four-pane side-hung casement on one side and a single-pane top-hung casement on the other. The five-bay side elevations have tall end piers and four shorter piers that support the rest of the wall.

On the southeast elevation, there is a sliding ledged and braced double vehicle door alongside a secondary steel pedestrian door. Each bay on the northwest elevation contains a 10-pane window. The gable elevations are divided into three bays by pairs of piers, with each bay featuring a galvanised-steel window. The northeast gable has three paired ventilation bricks, while the southwest gable includes a square ventilation louvre above the central window. The gabled roof has been coated in grey resin and fibre-glass to replace the failing felt and is finished with timber barge boards. Plastic gutters are affixed to timber fascia boards on the side elevations.

Inside, the building is divided into two rooms: an open four-bay workshop and a one-bay storeroom located in the eastern bay. The interior has a concrete floor and painted brick walls, with internally projecting brick piers. These piers feature painted stone corbels that support the timber lattice Belfast roof trusses, which in turn carry a timber plank roof lining. At the southwest end of the room, there is a stone block that may have served as a stove base.
