Reading Enfield Council's approvals in N13
Palmers Green comes under Enfield, although part of N13 falls to Haringey, and every Enfield decision goes on the council's public register. The newest loft decisions from Enfield's wards here are listed below whatever the outcome, so there's no need to second-guess what the council accepts.
On an Edwardian N13 terrace the same design questions come up each time: how far the dormer sits back from the eaves (permitted development asks for at least 20cm where practicable), how many rooflights go in the front slope, whether the new rear window becomes a Juliet balcony, and whether the back addition gets a dormer of its own. Answer them inside the volume allowance and the scheme can go in as a lawful development certificate, which confirms it in writing before you build. Inside the Lakes Estate conservation area that route is closed: a dormer there needs a householder application, and the estate has an Article 4 direction as well.

Palmers Green's rooftops — and which loft suits each
Palmers Green is a coherent Edwardian suburb, but the right loft still depends on your roof.
Edwardian terraces (the heart of N13). There's no hip to work with, so the standard solution is a rear dormer spanning the back slope — generally £40,000–£75,000 for a double bedroom and en-suite — or a mansard (£60,000–£100,000) when you're after the most floor area and full headroom right along the rear roof.
Edwardian semis and homes with back-additions. Where a property keeps its original rear outrigger — a common sight in N13 — the L-shaped dormer is the move that pays: a main rear dormer with a return carried over the addition, which can yield two or three rooms from the single project (£65,000–£95,000).
Inter-war hipped semis (the N13 fringes). On the rare semi that carries a hipped roof in place of a gable end, a hip-to-gable conversion with rear dormer (£55,000–£90,000) reclaims the side hip and tucks a dormer in behind, delivering a double bedroom with its own bathroom.
Where head height is already good. A Velux conversion leaves the roofline exactly as it is for £30,000–£45,000 — a neat way to win a home study or a single bedroom.

Honest numbers
What a loft conversion costs in Palmers Green in 2026
These ranges are realistic all-in build costs for Palmers Green, taking in labour and materials to a good standard but leaving aside VAT, fees and loose furnishings:
| Loft type | Typical Palmers Green cost | On-site time | Usual planning route |
|---|---|---|---|
| Velux / rooflight conversion | £30,000 – £45,000 | 6–8 weeks | Permitted development |
| Rear dormer | £40,000 – £75,000 | 6–9 weeks | Usually permitted development |
| Hip-to-gable + rear dormer | £55,000 – £90,000 | 7–10 weeks | Usually permitted development |
| L-shaped dormer | £65,000 – £95,000 | 8–10 weeks | Usually permitted development |
| Mansard | £60,000 – £100,000 | 8–10 weeks | Often a full application |
As a rule of thumb, Palmers Green loft costs run £2,800–£4,200 per square metre — North London rates, well above the national average. After a free site visit we put everything into a fixed, itemised quote — the figure you agree is the figure you pay.
Permissions, handled
Planning a loft conversion in Palmers Green
Most Palmers Green lofts don't need a full planning application. Because an Edwardian terrace puts most of its volume over the back slope, the work generally falls inside permitted development — which on a terrace caps the added roof volume at 40 cubic metres, rising to 50 cubic metres for a semi or detached house, provided you build nothing ahead of the original front roof slope.
A Lawful Development Certificate (£274) is the sensible piece of paper to obtain: it states for the record that the conversion was permitted development, which is exactly what a buyer's solicitor wants to see. A full application only comes into play for the exceptions — a mansard, say, or a house that has already drawn down its allowance — and the fee then is £548 (from April 2026) plus the £91.02 portal service charge, with Enfield aiming to turn standard householder applications around in roughly eight weeks.
Two other sums to factor in. Building control will want £500–£1,500 to certify the job. And since Palmers Green is built mostly of terraces and semis sharing a wall with the house next door, the Party Wall Act is usually a factor — budget £700–£2,500 per neighbour if it comes to appointing surveyors, while the cost falls away entirely when a neighbour returns written agreement within 14 days. We handle the notices for you and open the neighbour conversation the moment the design settles.

Questions, answered
Palmers Green loft conversion FAQs
How much does a loft conversion cost in Palmers Green?
Typically £40,000–£75,000 for a rear dormer, £65,000–£95,000 for an L-shaped dormer, and £60,000–£100,000 for a mansard — excluding VAT and fees. Expect N13 to land at roughly £2,800–£4,200/m², the usual North London band. The precise cost lands as a fixed, itemised quote after a free site visit.
Do I need planning permission for a loft conversion in Palmers Green?
Generally no — the majority go ahead as permitted development, which needs no planning application at all. Where a full application is needed it's usually a mansard, a dormer in the Lakes Estate conservation area, or a house that has already drawn on its permitted development allowance.
What loft works best on an Edwardian house in Palmers Green?
For most N13 houses it's a rear dormer worked across the back slope; where the home retains an original rear addition, an L-shaped dormer that carries a return over it can unlock two or three rooms together.
How long does a Palmers Green loft take to build?
Reckon on six to ten weeks on site — a rear dormer at the lower end, an L-shaped dormer wrapping a back addition at the higher. The drawings and design phase that precedes it runs to a couple of weeks, and securing a Lawful Development Certificate is typically swifter than going the full-application route.
Is my Palmers Green home in a conservation area?
In N13 the conservation area to know is the Lakes Estate, which also carries an Article 4 direction. We look your address up on Enfield's conservation map during the free consultation, before any design work starts.

What clients say
Rated 5.0 on Google
“Used The Extension Company for a loft conversion on our semi detached in Barnet and couldn't be happier. They explained what was possible at the first visit, sorted the planning side, and gave a fixed price with no surprises at the end. The hip-to-gable and rear dormer gave us a big double bedroom with an en-suite. Tidy, professional and finished on schedule. Would recommend to anyone in North London thinking about a loft conversion.”
“We had been putting off our loft conversion for years because the whole process felt overwhelming. The team made it much easier than expected and handled the drawings, planning and build for us. We now have a lovely extra bedroom and shower room.”
“Excellent experience with The Extension Company. They completed our loft conversion and delivered exactly what they promised. The new bedroom and en-suite have added valuable space to our property in Barnet, the quality of the workmanship is first class. The team were friendly, knowledgeable and always happy to answer questions throughout the build.”
“Couldn't be happier with our loft conversion. We were expecting the build to be stressful, but it was actually a lot easier than we'd imagined. The lads were friendly, worked hard, and the quality of the finish is spot on. The extra room has made a massive difference and has given us the space we needed without having to move. Very pleased with the end result.”
“The Extension Company built a 5m single storey rear extension on our Victorian terrace in Crouch End. Went down the permitted development route so no planning application needed, which they explained up front and saved us months. Kitchen-diner now opens onto the garden with sliding doors. £87k all in, matched the quote.”
“From the initial site visit onwards to my property in Barnet, we felt that the team actually listened to what we wanted. They suggested a few changes to the layout that we hadn't considered, and those changes have made a huge difference. Would definitely use again and recommend”
