Redevelopment of Council Offices, Bourne Hill

Environmental Impact Assessment for an office redevelopment with particular heritage sensitivities.


Salisbury District Council


Salisbury District Council (SDC) planned to centralise its operations throughout Salisbury into one office base at Bourne Hill. The development involved renovation of the Grade II* Listed Council House, demolition of a Victorian extension and construction of new offices within the parkland garden. The application site is within a Conservation Area and an Area of Archaeological Significance, adjacent to the Grade II* Listed building and close to a Scheduled Monument within the garden.

The Council commissioned Landmark in 2005 to undertake an EIA to inform applications for Planning and Listed Building consents. Consents were granted in 2006 and demolition of the Victorian extension commenced. Throughout the enabling works, local residents protested against the scheme and following a change of local government administration in May 2007, construction was halted and the size of the new extension was revised. Fresh planning and listed building applications (and EIA) for a new scheme were submitted in February 2008.


Landmark managed the EIA, advised the development team and liaised with the planning authority and statutory consultees to bring together a complex set of information to inform the consents process. In addition to the constraints to re-development posed by the historic setting and structures, centralisation of staff and functions into one site raised a range of other environmental challenges.

The development masterplan and detailed prescriptions for impact avoidance and mitigation were informed by the EIA, which also set out the principles for development and environmental management that were incorporated into planning conditions to secure delivery of the scheme.

Client Benefits

Tight, well-informed management of the EIA process gave clarity and confidence in the quality of the applications to the client and the receiving authority and achieved a Good/ Excellent Grade at Review of the EIA by the Institute of Environmental Management and Assessment (IEMA).

Planning and Listed Building consents were granted in 2008 and the successor authority to SDC, Wiltshire County Council, subsequently developed the scheme.
