British Aerospace Staff Mess

The British Aerospace Staff Mess, built in 1934 by Geoffrey Monro for the de Havilland Aviation Company, is a two-storey staff mess adjacent to offices. It features white painted reinforced concrete and a flat roof concealed by a parapet. The building has a distinctive plan, with the managers' mess located at the northeast end, characterized by rounded corners, curved windows, and horizontal bands of windows supported by green glazed tile piers and metal frames.

At the northeast end, there is a two-storey entrance and stairhall block with a broad metal frame window on both floors, and an integral doorway on the left with a cantilevered canopy. The larger staff mess to the southwest has similar ground floor windows and five tall first floor windows on either side. The ends of the staff mess have segmental raised parapets, and the southwest end features a projecting entrance block with a horizontal window band on the first floor and a doorway with a cantilevered canopy, flanked by integral windows.

Inside, the managers' mess includes an open-well staircase with an unpierced balustrade and a moulded wooden handrail that ramps up at the corners. This building served as the mess for the offices of the de Havilland Aviation Company, where iconic aircraft such as the Tiger Moth, Dragonfly, Mosquito, Vampire, and Comet were designed.
