A historic building survey undertaken by MOLA (Museum of London Archaeology) at Moreland and Riverdale Buildings Lower Sunbury Road, Hampton, London TW12, in the London Borough of Richmond. National grid reference to the approximate centre of the site is 513697 169465. The survey was commissioned from MOLA by Blackbottle Ltd to analyse and record the structure. The investigation took place in June 2014 and conformed English Heritage recommended 'Level 3' standards. The surveyed standing structures Moreland and Riverdale are two large redundant buildings belonging to the 19th century waterworks. The site is being developed to create laboratory space within the refurbished Moreland and Riverdale buildings. Both these buildings and the whole site of Hampton water works Grade II listed. During the survey buildings on the site were recorded in their present condition by means of photography and with the use of existing scale drawings supplied by the client. Detail and general views of the structure in its existing spatial context, internal and external fabric were also photographed prior to its alteration. The Morelands Building was constructed in 1886-7 as a water pumping station to a design by Joseph Quick. Two engine houses stand either side of a centrally placed boiler house in a scheme classic to Victorian pumping stations. The western Engine House was still used until recently by Thames Water as a pumping station, however Beam House to the east was converted into offices during the 1950s. The Riverdale buildings were constructed in 1895-1900 to house and operate the new improved engines designed by James Restler. The entire Riverdale site comprises two connected wings. Although the original coal powered engines were replaced with diesel engine and then electric engines, the building remained in use as a pumping station until the 1950s.
