Jane quickly realised that managing and future-proofing electrical and mechanical services installations in the NHS, was one of the most difficult design challenge. In this listed building the roof trusses and top lighting were the striking features. Jane designed a ceiling tray constructed in birch ply that ordered the services, provided task lighting in the larger spaces, and sound-proofing in the smaller consulting rooms, whilst allowing the trusses to be exposed and natural lighting to be retained. Only white was allowed for the walls, as the staff used patients’ skin colour as a way of assessing their condition. Three carefully designed screens were built, which allowed the staff to survey the waiting area whilst providing some privacy to patients giving blood.
