Seven Lysaght hangars in total form a group adjacent to the Bellman hangar. They are relatively intact and have not been substantially modified in terms of their structure or fabric. One Hangar is currently used as part of the Museum display. These hangars are constructed with steel portal frames with steel cladding (a heavier gauge then others on the base) supported on a concrete floor. External walls are supported on concrete plinths and large sliding panelled doors hung on overhead track slide open to allow access for large vehicle/aircraft. Louvre windows allow light and ventilation in to the building while bays of translucent roof sheeting allow additional light in from the roof.
