Jaguar Land Rover’s BREEAM Excellent Engine Manufacturing Centre houses 1400 staff and is comprised of buildings including machine and assembly halls which are flanked by offices, social support spaces and a community educational centre. Large span steel roof framing, supported on columns spaced at 30m intervals, is arranged with an open truss form to give high-level services distribution, a clear hierarchy, modulated to suit the north light architecture. This, incorporated with the sawtooth roof forms, breaks down the massive scale to humanise the production space.
