GS Renovation builds house extensions in St Albans, from single storey rear additions to larger structural projects. The planning position here is unusual, because the adopted plan dates from 1994 while a new plan sits at examination. We appoint structural engineers, build to their calculations, and coordinate building control applications and inspections.
The adopted plan your extension is judged against dates from 1994
The current adopted Local Plan for St Albans is the District Local Plan Review 1994, adopted on 30 November 1994, and it is one of several documents that together make up the Development Plan for the district. St Albans City and District Council describes it as one of the oldest in the country. That is the council's own description, not ours.
Not all of it still applies. Local Plans expired after 27 September 2007 unless saved, and a Direction made in 2007 saved specified policies of the District Local Plan Review 1994. The council published a saved and deleted policies version in July 2020, so the live policy set is narrower than the original document. Check which version a policy reference comes from before relying on it.
The emerging plan already carries weight in decisions
St Albans City and District Council states that its emerging Local Plan now has significant weight in decision making, with its policies an important material consideration. The new draft Local Plan was submitted to the Planning Inspectorate for independent examination on 29 November 2024 under Regulation 22. A consultation on Main Modifications under Regulation 24 commenced on Monday 13 April 2026.
For a householder extension that means two policy sets are live at once, the saved 1994 policies and the emerging ones. We are a contractor, not a planning consultant and not an architect, so we do not argue your case for you. We build what is consented, appoint the structural engineer, and coordinate the building control side once permission is settled.
Four Article 4 areas where permitted development has been removed
Four heritage Article 4 Direction areas cover parts of St Albans District: Verulam and Fishpool Street, Sopwell Lane and Albert Street, Cunningham Avenue and Childwickbury. The Sopwell Lane and Albert Street Direction, dated 5 July 1990, removes permitted development rights under Part 1 Classes A to H and Part 2 Classes A to F. Part 1 Classes A to H is the part that covers extensions, roof alterations and porches.
The Verulam and Fishpool Street Direction, dated 2 January 1991, removes Part 1 Classes A to H and Part 2 Classes C to F. It is recorded as removing Part 2 Classes C to F only, so it does not remove Part 2 Class A, which covers gates, fences, walls and other means of enclosure. The Sopwell Lane and Albert Street Direction does remove Class A. The two are not identical, and the address decides which applies.
Foundations sit on chalk with sand and gravel over it
BGS 1:50,000 mapping records the bedrock beneath St Albans city centre as the Seaford Chalk Formation, with the superficial deposits above it mapped as the Satwell Gravel Member, sand and gravel within the Kesgrave Catchment Subgroup. Across Fleetville, Marshalswick and The Camp the superficial cover is mapped as Kesgrave Catchment Subgroup sand and gravel, deposits formed by an ancestral River Thames.
Beneath the London Road area of south St Albans, close to Cunningham Avenue, BGS maps River Terrace Deposits of sand and gravel. Sand and gravel over chalk is a different foundation problem from clay, and it changes excavation, trench stability and drainage falls. The structural engineer we appoint specifies the foundation and we build to that specification.
- Drainage diversion and build-over agreements with the water authority
- Levels, drainage and landscaping made good around the new build
- Single and double storey extensions
- Party Wall Act notices for excavation near a neighbour's wall
- Brickwork and mortar matched to the existing elevation
