One of the first buildings to be completed on the Jubilee Line Extension, this was WilkinsonEyre's first major new-build project. Won as the result of a design competition, the brief called for a complex providing train maintenance and stabling facilities alongside extensive office and ancillary buildings. A 'supershed' was the ideal solution for the main train shed – an industrial building of considered design, providing flexible, durable space. Here, a 100m wide, 190m long arched roof covers eleven maintenance bays.
