Port Marine

Design process

There were previously two coal-fired power stations on the site. These were decommissioned in the 1970s, but it was not until ten years later that a developer, Crest Nicholson South West Limited, started working with North Somerset Council to develop a master plan. Outline planning approval was received in 1995, with detailed approval for the 18 separate parcels in 1999. Crest Nicholson then acquired the whole 221 hectare (545 acre) site.

The masterplan was developed by Llewelyn-Davies in conjunction with BBA Architects and Planners, who also designed the first two parcels. Austin-Smith:Lord, Charter Consultant Architects and A&PG Architects were responsible for other parcels, with landscaping carried out by the Derek Lovejoy Partnership. 50 affordable dwellings have been provided in partnership with Knight Stone Housing Association.

The site was decontaminated ready for construction. This involved the removal of pockets of oil. The power station had been demolished to 2m (7ft) below ground, but 30m (98ft) deep remaining structures required the engineers, Ove Arup & Partners, to design special flexible techniques for the foundations.
