Winner - National Cold War Exhibition, RAF Museum Cosford
Commissioning authority: Royal Air Force Museums
Principal designer: Feilden Clegg Bradley Architects
Principal contractor: Galliford Try
This landmark building in Shropshire is the new home for 17 large aircraft, as well as many other exhibits and interactive displays. Together these form the first exhibition dedicated to the Cold War, which is already attracting large numbers of visitors from near and far.
Central to the £9 million project is the vast and striking hangar at RAF Cosford, the form of which is two curvilinear triangles which meet along a central divide. Innovation and technical expertise both in design and construction were required to create this technically challenging structure, but a highly energy-efficient and low-maintenance building was also necessary.
The primary structure consists of straight trusses fabricated from circular hollow sections, and each truss is misaligned from one to the next to define a hyperbolic parabola.
Linear geometry transforms to curvilinear geometry by twisting each section of structure and its spans between the trusses. Considerable design innovation was required to achieve the resulting roof profile, the external surface of which is clad with an aluminium standing-seam insulated roofing system.
This complex project was achieved through strong collaboration across the design team, which worked well with the client to ensure that the building worked in harmony with and to the advantage of the exhibitions it would house.
