<P> The Compass Centre was designed by Nicholas Grimshaw & Partners, which designed the core, external works, and shell of the building . Compass Centre is alongside but slightly askew from Heathrow's northern runway, with the Northern Perimeter Road, T5 Long Stay car park and Compass Centre car park between the runway and the Compass Centre . In 1995 Penny McGuire of The Architectural Review said that "Its shining glass and bright blue clad exterior reminds you, particularly when seen glowing at night, that one of the largest and busiest airports in the world is otherwise encumbered with a really grim collection of buildings . Decent ones are a rare sight around here ." It was designed to house up to 800 British Airways employees . British Airways wanted a large, on - airport facility close to its operations, so it decided to use the Compass Centre . </P> <P> Compass Centre consists of a linear arrangement of three blocks . Each block is serviced independently and has a glass atrium with glass links in between . The design stems from a client's request for a building that could be easily divided between tenants . The building can accommodate sub-letting and flexibility involving several tenants . Reinforced concrete was used to construct the structural frame due to economy, fire resistance, and speed . The frame has a raked roof slab and circular columns . Glass was the primary material used to construct the shell, because glass has little radar interference, and in the words of McGuire, can be "acoustically efficient ." The design limits heat gain and solar glare, and the building environment is sound - proofed . </P> <P> The British Council for Offices awarded the building the "Best Delivered Workplace ." </P>
