Jehovah’s Witnesses Britain Headquarters, Chelmsford - light case study


Redevelopment of a 33-hectare brownfield site for a new live/work charity headquarters including buildings for accommodation, offices, production and support services, together with on-site roads and parking, footpath network and expansive landscaping scheme.

The previous site use was a car breakers yard. Some existing ponds and the site ditch network were in real need of remediation.

Residence blocks have green roofs and rain gardens. The production buildings feed a rainwater harvesting system. Permeable paving was used for parking courts and footpaths. Roads drain via sheet runoff into roadside swales. Treatment is provided in online ponds, pocket wetlands and a bioretention bed. Conveyance is via swales and existing ditches into final attenuation ponds.
