Heathrow Airport Terminal 5, New TerminalBAA

Terminal 5 was conceived as a world-class multi-model transport interchange to bring Heathrow Airport in to the 21st century.

The main terminal building (Concourse A), is a celebration of flight. It was constructed over eight storeys; five above ground and three below. It’s simple, flexible design creates a series of dramatic spaces at all times focusing on the passenger experience. A graceful flowing roof floats above the main concourse, independently supported on elegant steel 'trees'. A wrap of full height glazed facades affords a direct visual relationship with the airfield and serve to create intuitive wayfinding routes through the building.

Concourse B is the first of two satellite buildings. A scaled-down version of the main terminal, it is still bigger than the existing Heathrow Airport T4. The design creates a series of exciting transitional and dwell spaces utilising carefully considered high-quality materials. A below-ground track-transit system, rail links, baggage networks and ancillary buildings complete phase 1 of the T5 project.

Concourse C, the second satellite terminal, is a stand-alone satellite building connected to T5A and T5B via an underground railway system. The building increases T5's handling capacity to 35 million passengers per annum and was constructed over seven storeys; four above ground and three below.

The project was one of the largest contemporary construction projects in Europe and has received numerous awards, including the RIBA National Award 2008.
