Statement of Significance

Description of Historic Place

Building 49, also known as Hangar 5, is part of a hangar line located at Canadian Forces Base (CFB) Trenton. It is a large, rectangular workshop hangar with an exterior clad in a smooth, stucco finish. The building has a flat roof, a stepped roofline on its west elevation and a central parapet on its front. The building has regular and large doors as well as both regular and large size multi-pane windows. The designation is confined to the footprint of the building.

Heritage Value

Building 49 is a Recognized Federal Heritage Building because of its historical associations, and its architectural and environmental values.

Historical Value
Building 49 is closely associated with the Royal Canadian Air Force (RCAF) at Trenton, and its important role during the Second World War as the Central Flying School for the British Commonwealth Air Training Plan (BCATP). It is also associated with the early development of the RCAF at Trenton, and as part of the service component represented by the hangar line, it was a key aspect in the success of the BCATP.

Architectural Value
Building 49 is valued for its good aesthetic and functional design. Its Art Deco design was built to a standard architectural style and colour scheme as part of a distinct line of hangars dating from the early development phase of RCAF Trenton. Designed as a double landplane hangar to maintain and store aircrafts and parts, its use of a flat roof with double Warren trusses combine to provide a large service area, and the pattern of various sized windows allow plenty of light into the building; all of which add up to a good functional design.

Environmental Value
Building 49 is compatible with the present character of its military base setting at CFB Trenton. As part of a distinctive and unified hangar line, it is a familiar building on the base.
