Building 48 (Works Services Building)

The Works Services Building, also known as Building 48, is a Grade II listed structure located at the Imperial War Museum Duxford, built in 1935 by the Air Ministry's Directorate of Works and Buildings. It is constructed of yellow brick in Flemish bond with a slate roof and brick stacks. The building has a rectangular single-storey plan that includes separate offices for the clerk of works and the station engineer, a fitter's shop, and a large store. An attached yard, enclosed by brick walls, is designated for the storage of building materials.

The exterior features concrete lintels over all openings. On the south elevation, there is a small six-pane steel casement window to the right of a half-glazed door with an overlight. Further to the left, a similar set of double doors is flanked by multi-paned transomed steel casements. The roof has hipped returns to the rear wings, with a lean-to on the left that has a similar door and flanking small casements. The rear also has similar fenestration, with the right return featuring double doors leading to the workshop, which includes skylights.

Internally, the building retains its original doors and joinery. Duxford is recognized as the finest and best-preserved example of a fighter base in Britain up to 1945, showcasing a complete group of First World War technical buildings alongside typical inter-war RAF structures. The site has significant historical associations with the Battle of Britain and the American fighter support for the Eighth Air Force. The Works Services Building remains externally unaltered and served a crucial support function for the base, contributing to its historical importance.
