Report by P Wakefield on a rapid survey of this complex, which includes the water works and electricity generating station for the hospitals of the former Horton Manor estate. The buildings date from 1901 and were designed by W Clifford Smith, engineer to the London County Council Asylums Committee. The boiler house has suffered a change of use that involved the loss of its chimney, but the water works and generator hall survive relatively intact, albeit derelict. A disused reservoir probably served the original steam boilers. Following WWII another boiler house was constructed, which supplied steam heating to the whole of the hospitals cluster. (SIHG 100)
