Enfield controls the Fox Lane (Lakes Estate) conservation area; N13 is a settled Edwardian family market.


The borough-level guide to house extensions in Enfield sets out how the same work is handled across the rest of the authority.
House extensions in Palmers Green are dominated by single-storey rear and side-return additions on N13's edwardian and inter-war bay-fronted semis and terraces, with double-storey and wrap-around schemes where the plot allows. Enfield Council weighs depth, height and neighbour daylight; many extensions across Palmers Green, Broomfield Park, Bowes Park fringe are Permitted Development, which we confirm with a Lawful Development Certificate before you build.
The whole spectrum — rear extensions, side returns, wraparounds, double-storey, basement digs. Planning-led design with detailed technical phase, ideal for edwardian and inter-war bay-fronted semis and terraces typical of Palmers Green.
Across Palmers Green, Broomfield Park, Bowes Park fringe in N13, the dominant property is edwardian and inter-war bay-fronted semis and terraces around palmers green, with larger houses toward broomfield park. That stock shapes what house extension drawings looks like here: the right approach for a period terrace differs from a mansion-block flat or a new-build, and Enfield Council judges each on design quality and neighbour impact. We survey the specific Palmers Green property, confirm the planning route — Permitted Development, a Lawful Development Certificate, or full planning — and draw a council-ready set tailored to the N13 streetscape.

Yes. The Edwardian and inter-war bay-fronted semis around Fox Lane and Old Park Road suit rear and side extensions plus loft conversions, much of it within Permitted Development outside the conservation area, confirmed with a Lawful Development Certificate. We confirm the route and draw to Enfield's checklist.
The Fox Lane (Lakes Estate) conservation area protects the Edwardian planned streets with controls over bays, materials and front gardens, so extensions there need full planning with a Heritage Statement. We design sympathetically to the estate's character and submit to Enfield.
Usually yes on the semis — a hip-to-gable plus rear dormer within the volume allowance, confirmed by a Lawful Development Certificate, provided you're not in the Fox Lane conservation area. We check the constraints for your road and draw it for Building Control.
With N13 houses around £650,000-£950,000 and a direct rail link to Moorgate, a rear extension or loft adds family space worth comfortably above the build and drawing cost. N13 offers strong north-London value.
Enfield Council charges its own statutory application fee (currently £548 for a householder planning application, £610 for a full application). We quote the drawings as one fixed price and the free site survey covers every N13 address.
For a N13 project across Palmers Green, Broomfield Park, Bowes Park fringe, expect roughly 3–4 weeks from instruction to submission: week 1 the measured survey, weeks 2–3 the drawings and your revisions, then validation and the statutory determination by Enfield Council (8 weeks for a householder application). We carry the Palmers Green application through every officer query to the decision.
Palmers Green (N13) sits primarily in Enfield, so applications are decided by Enfield Council. Conservation areas within N13 include Fox Lane (the Lakes Estate), Broomfield, where full planning and a Heritage Statement are required. We confirm the planning route for your exact address before quoting.
Almost always. Any structural work behind house extension drawings in Palmers Green — new openings, steel beams, loft floors, foundations — needs Building Regulations approval covering structure (Part A), fire escape (Part B) and insulation (Part L), submitted to Enfield Council Building Control or an approved inspector. On N13's typically terraced and semi-detached stock, a Party Wall notice to adjoining neighbours is normally required before the steelwork. We coordinate both as part of the Complete package.
In value terms, yes. The bigger risk is an unapproved or non-compliant scheme — which is why council-ready drawings and a clean Building Control sign-off matter on N13 homes.

Every N13 postcode district we draw in, the stock that dominates it and the authority that validates a house extension there. N13 fees below are the statutory England rates for 2026, not house extension estimates.
| Postcode | Area | Dominant stock | What it means for a house extension |
|---|---|---|---|
| N13 | Palmers Green | Edwardian villas, 1930s semi-detached | N13 covers Palmers Green only; Enfield Council handles the house extension. |
| N9 | Lower Edmonton | Victorian terraces, post-war estates | Adjoining district to N13, also inside Enfield for house extension purposes. |
| N14 | Southgate | 1930s semi-detached, Edwardian villas | Adjoining district to N13, also inside Enfield for house extension purposes. |
| N18 | Upper Edmonton | Victorian terraces, post-war estates | Adjoining district to N13, also inside Enfield for house extension purposes. |
Roof pitch, wall build-up and plot depth change every few N13 streets, and each one changes what a house extension can achieve at that address.

Designation costs a N13 (Palmers Green) owner the permitted-development route: a house extension then needs a £548 householder application over 8 weeks, in place of the £249 prior approval route that takes 6 weeks. Enfield Town is the N13 (Palmers Green) designation that most often changes a house extension design.
N13 (Palmers Green) permitted development status: there is no borough-wide direction from Enfield Council, so a house extension at a N13 address is normally still permitted development.
