The Power House was designed by the architects William Curtis Green and J. Clifton Robinson;[2][3] the building engineer was a Mr. Parshall.[1] It is described in Bridget Cherry and Nikolaus Pevsner's The Buildings of England as a "monumental free Baroque brick and stone composition".[1] The building is rectangular, with five bays on one pair of faces, and three bays on the other pair. There is a large cornice with brackets above enormous arches which have long voussoirs in stone.[1] The façade above the front entrance is adorned with two large carved female figures that represent 'Electricity' and 'Locomotion'.[1][2] As built, it had a 260-foot high steel smoke-stack.[4]
Cherry and Pevsner call the Power House "by far the most exciting building"[1] of Chiswick High Road and Turnham Green, and "the best surviving example in London from the early, heroic era of generating stations whose bulky intrusion in residential areas was tempered by thoughtful architectural treatment".[1]
Usage
The building had a short working life as a generating station; in 1917 power generation was taken over by the generating station at Lots Road, Chelsea.[2] The Power House however continued to be used as a substation until 1962, when the trolley bus service was closed. In 1966 the building's chimney was demolished.[2]London Transport decided to redevelop the site. This led to an outcry, and the Victorian Society campaigned for the protection of the building from the developers. This resulted in a Grade II listing for the building in 1975;[5] it was one of the first Victorian buildings to be so nominated, and the first for one built in the 20th century.[6]
In 1985, the upper part of the building was converted into residential accommodation, including a penthouse which is split over three levels,[6] and flats "ingeniously tucked into the roof".[1] The architects were David Clarke Associates.[1]
