Comprehensive Development at Adanac Park

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


Trustees of the Barker Mill Estate


The Landmark Practice was appointed to scope and manage an Environmental Impact Assessment (EIA) and prepare the Environmental Statement (ES) to accompany a planning application for development of a 32 ha business park at Adanac Park.

The planning application was for a ‘hybrid’ scheme, comprising both full planning and outline planning components. The application for the new Ordnance Survey Head Office, to be relocated from its existing offices in Southampton, was made in full, and outline consent was sought for a further circa 60 000 sq m of high quality office, research and manufacturing uses.


Allocated in the Local Plan for high quality office, research and manufacturing development, the site was subject to a number of sensitivities. Its close proximity to sites of County and European importance for nature conservation introduced risk of potential impacts to protected species and sites and a need to maintain habitat connectivity by incorporation of green infrastructure within the development. Proximity to residential areas and highways also necessitated thorough assessments of landscape and visual impact, artificial lighting, noise, hydrology and traffic.

The complex EIA responded to the change in the UK EIA Regulations following the European Court of Justice ruling in 2006, that both outline and reserved matters parts of staged development schemes may be subject to EIA. Landmark also undertook the landscape and ecological impact assessment to inform the EIA and prepared the landscape masterplan for the entire site.

Client Benefits

An approach to the EIA was devised that satisfied the requirements of Article 3 of the General Development Procedure Order (GDPO), the requirements of the EIA Regulations and respond to case law, whilst also retaining maximum flexibility for the outline element of the scheme for our clients. Planning approval for the hybrid scheme was granted in January 2008 by unanimous planning committee vote.
