Planning rules that apply in Enfield
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
The planning position for a specific Enfield address depends on its history and any designations, which is why we check it at the first visit.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
Covering Enfield
Postcode districts we cover around Enfield include EN1, EN2, EN3, N9, N14, N21. The same team covers Ponders End (2 miles), Edmonton (2 miles), Palmers Green (3 miles), Enfield Lock (3 miles), all within easy reach.
Just over the Hertfordshire border, Cheshunt is about 4 miles away. Across London, terraced houses with narrow side returns and tight access are the norm, which shapes everything from party wall notices to how materials reach the back garden.
What we take care of
- Removal and disposal of the old conservatory
- Insulated walls and roof to current regulations
- Trial holes to check the existing foundations
- New or upgraded foundations
- Opening widened into the house if wanted

Your questions about a conservatory replacement in Enfield
Do you cover all of Enfield?
Yes. We cover Enfield and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does a conservatory replacement take to build in Enfield?
On site, typically 8 to 14 weeks once approvals are in place. Before that, allow 4–12 weeks design and approvals.
Who do I contract with for a conservatory replacement in Enfield?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Can I keep the existing base?
Sometimes, but conservatory bases are often too shallow for solid walls. Trial holes tell us before we confirm the price.
Is it worth replacing a conservatory with an extension?
If the conservatory is unusable for much of the year, usually yes. A solid extension gives a heated room that counts as proper living space. Our guide range is about £2,400 to £4,550 per m² including VAT, including removal.
