Leatherhead

This project involved the design and construction of a new waste transfer station and household waste recycling facility at Randalls Road, Leatherhead on behalf of SITA Surrey.

Works comprised the construction of an 800m2 steel framed and clad building with internal in-situ RC push-walls 5m in height (including a full sprinkler system), a single storey office building using brickwork and timber facing on prefabricated timber frame under a timber trussed tiled roof, and construction of an asphalt road and ramped access to high level parking where the public can deposit bulky materials into segregated bins from raised walkways.
