An extension in Epping is judged against two development plans, and possibly a conservation area on top of them. We build to the structural engineer's design, coordinate the building control application and inspections, and work to the drawings your architect or designer produces. We do not produce structural calculations or planning drawings ourselves. Free, no obligation quotations, and the company is fully insured.
Two adopted plans now set the rules
The Epping Forest District Local Plan 2011 to 2033 was adopted at an Extraordinary Meeting of the Council on 6 March 2023 and is the statutory development plan. The Epping Town Neighbourhood Plan 2023 to 2033 was adopted by full council on 23 July 2026, following a referendum on 18 June 2026, and now forms part of the development plan for Epping.
Policy 11 of that neighbourhood plan requires new development to take the Essex Design Guide into account and to respect the design qualities and character of the local area. For a householder extension, that means the design is measured against a town level document as well as a district one, so the design work is worth doing properly before an application goes in.
Three conservation areas sit inside the parish
The Epping Town Neighbourhood Plan records three conservation areas inside Epping parish: Epping town centre, Bell Common and Coopersale Street. In a conservation area in the Epping Forest district you need planning permission for a side extension. You also need it for a two storey rear extension.
Inside those boundaries, permitted development is not the shortcut it is elsewhere. The sequence becomes design first, permission second, and construction after, and a programme built the other way round loses time it cannot recover.
What you are founding on changes across the ridge
Epping town sits astride a ridge about 100 metres above sea level, separated from the outer suburbs of London by the forest that bears its name. The British Geological Survey's 1:50,000 map sheet 240 is named Epping, after the town. A superficial cap of Stanmore Gravel Formation sand and gravel is mapped over the southern part of that ridge, at Buttercross Lane, Cottis Lane, Bakers Lane, St John's Road, Station Road and the southern end of the High Street. At the market place and the Church Hill end of the High Street no superficial deposit is mapped, and the Claygate Member is at the surface. The survey records the Stanmore Gravel as averaging 3 metres thick and reaching 7 metres.
Water is the other half of the picture. The Environment Agency's Flood Map for Planning places Epping High Street, Hemnall Street and Lindsey Street outside both Flood Zone 2 and Flood Zone 3. It does map surface water flood extents at the 3.3 per cent annual chance level on Cottis Lane and Bakers Lane, both running off the High Street. Epping Forest District Council requires a Flood Risk Assessment for householder development in flood zone 2 or 3, including sheds, garages and games rooms within the curtilage as well as extensions to the house.
Trees and drawings the application will need
Every tree with a stem diameter of 75 mm or more inside an Epping Forest district conservation area is protected under the Town and Country Planning Act 1990. You must give the council six weeks notice before carrying out work on any tree in a conservation area, and work may only start if the council does not object or the six weeks expires. Where a site is in a conservation area, or has trees protected by a Tree Preservation Order, the council requires all trees within or next to the site to be shown on a plan. A BS 5837:2012 arboricultural impact assessment is required if any of them are affected.
The council also requires existing and finished ground levels on the drawings where a proposal changes ground levels, plus a cross section through the proposed building. On a sloping site that is not a formality, and we set out levels on site to match what was approved rather than what was assumed.
- Party Wall Act notices for excavation near a neighbour's wall
- Roof works and structural alterations at roof level
- Architectural drawings and structural engineer coordination
- Drainage diversion and build-over agreements with the water authority
- Steel goalpost frames where the rear wall opens up
Why Choose GS Renovation in Epping
An extension here answers to a district local plan adopted in March 2023 and a neighbourhood plan adopted in July 2026, with the Essex Design Guide sitting behind both. Add a conservation area and permitted development narrows further again. We do not draw the scheme or write the calculations. We build what the engineer designs, coordinate the building control application and the inspections, and give you one point of contact for the whole build.
