Fore Street Is Protected. Your Street Probably Isn’t. House Extensions and Renovation in Edmonton N9 and N18
Edmonton confuses people, and the confusion costs them. Yes, there are conservation areas here. No, they almost certainly do not cover your house.
Enfield’s designations in Edmonton run along the old high street — Church Street and Fore Street — protecting a historic commercial spine. The residential terraces either side of it, where most people in N9 and N18 actually live, sit outside those boundaries and keep their permitted development rights. If you have been putting off an extension because you assumed you would need permission, it is worth ten minutes to find out.
We are Design And Build, an architect-led firm covering Edmonton. Design, structural engineering, planning, and construction on one contract. Ask us to check your address and we will tell you straight.
Where the Conservation Areas Actually Run
Two conservation areas cover the historic core: Church Street and Fore Street, Edmonton, the latter also known as Angel. Enfield first designated here in 1970 and the two share a single character appraisal, published in 2006, revised in 2009, reviewed by consultants in 2013 and again by the council in 2014 and 2015, and approved in its current form in September 2016 alongside management proposals.
Fore Street is a genuinely old road — the main route north out of London, drawing ribbon development from the seventeenth century, then rebuilt as the commercial centre of a growing suburb around 1900. The appraisal divides it into character areas, one of which runs south from the North Circular to College Gardens and then curves to Grove Street. That is the southern edge of the conservation area and also the southern edge of the borough: cross it and you are in Haringey, with a different council determining your application.
What this means in practice is a clean split. Frontages on the protected stretch of Fore Street are controlled. Side streets away from it generally are not. We check your address against Enfield’s conservation area mapping before doing anything else, because the answer decides whether you need an application at all.

The Bungalow Fronts — and Why They Matter If You Own One
There is a building type here you will not find described on most builders’ websites, and it turns up regularly in our Edmonton work.
When Fore Street became a shopping street around the turn of the twentieth century, owners did not demolish the houses. They built over the front gardens instead — single-storey shopfronts pushed forward to the pavement, with the original house left standing behind. The appraisal calls them bungalow fronts, and they survive along the street in numbers.
If you own one, you own two buildings stitched together: a period house at the back and an Edwardian commercial addition at the front, usually with different structure, different roofs, and different drainage. Converting the front back to residential, opening the two into one, or simply renovating without discovering the join too late — all of it needs someone who has seen the arrangement before. It is also, unavoidably, work on a protected frontage, so consent is part of the job rather than an afterthought.
Worth knowing too: Fore Street sits on Historic England’s Heritage at Risk Register. That raises the bar on what the council will accept, and it means sympathetic work here is genuinely welcomed rather than merely tolerated.
What We Build on Edmonton Houses
Away from the high street, N9 and N18 are made up of two-storey Victorian and Edwardian terraces and semis, with inter-war and postwar stock filling in around them. Compact plots, long back gardens, and the standard narrow rear addition.
Rear and side-return extensions are what these houses want. Building out across the back turns a cramped kitchen into a proper family room, and on most Edmonton streets it can be done under permitted development — no application, no fee, no wait. That is a real advantage over much of north London and it is the single most useful thing to establish first.
Loft conversions work well on these roof pitches. A rear dormer typically gives you a double bedroom with an en-suite, and away from the protected frontages it usually falls within permitted development too.
Whole house renovation — rewiring, replumbing, heating, insulation, structural alterations, layouts opened up, kitchens, bathrooms, interior design, joinery. A lot of Edmonton stock has had decades of piecemeal work and needs unpicking before it can be improved properly.
Conversions and HMO work. Edmonton has strong rental demand, and we do a fair amount of work for landlords. One thing to know before you commit: changing a house into a small house in multiple occupation needs planning permission anywhere in Enfield, whether or not you are in a conservation area. That catches investors out regularly.
Our architects and structural engineers are in house, so the drawings and the calculations are produced together and the scheme that gets designed is the scheme that gets built.
Flood Risk: the One Thing Edmonton Owners Should Check
Edmonton sits on the western edge of the Lee Valley, and parts of N9 and N18 fall within flood risk zones. This does not stop you building, but it does change three things.
It affects what the council will approve, particularly for anything at or below ground level. It affects how the work is detailed — floor build-ups, damp-proofing, drainage, and where services run. And it can affect whether a basement is sensible at all, which on some Edmonton streets it simply is not.
You can check the long-term flood risk for your postcode on the government service in under a minute, and we do it as part of every survey here. Finding out at design stage costs nothing. Finding out at building control stage costs a redesign.
Planning Applications and the Regeneration Backdrop
Where consent is needed, we prepare and submit it and handle Enfield’s planning department from validation through to decision, along with building regulations approval running alongside.
It is worth knowing that Edmonton is one of Enfield’s priority regeneration areas, with an adopted Area Action Plan and masterplan, the long-running Meridian Water scheme to the east, and substantial council-led housing delivery around Angel Edmonton. For a homeowner this mostly means context rather than constraint — but it does mean planning policy here is more active than in a settled suburb, and worth checking rather than assuming.
Where a scheme looks marginal, you will hear that from us before you fund it.
Party Walls on Edmonton Terraces
These houses share walls, so the Party Wall etc. Act 1996 applies to most of what we do here, often on both sides. Cutting into the shared wall for a beam does it. So does building up to the boundary. So does digging near the neighbouring house below the level of its own footings.
Get agreement in writing and it costs very little. Leave it late, or get no reply, and you are paying for appointed surveyors and an award. Our party wall surveyors serve the notices at the right point and deal with the neighbours from there.
How We Work
Free survey. We check the conservation area position, the flood zone, the construction, and the condition, then talk through what you want. You get an honest read on whether you need permission and what the work involves.
Drawings and calculations. Produced in house, together, to the constraints we have already confirmed.
Consents where needed. Application, building regulations, party wall notices, and all correspondence with Enfield.
Construction. One programme, one project manager, our own teams on site. Updates without you chasing.
Handover. Every snag closed out rather than logged, sign-off from building control, your certificates and warranties handed over, and our guarantee standing behind the work.
Straight Answers for Edmonton Homeowners
Do I need planning permission for a rear extension? On most Edmonton streets, no. The conservation areas here follow Church Street and Fore Street rather than the residential side streets, and Enfield’s Article 4 Directions do not cover Edmonton. So permitted development usually applies, subject to the standard depth and height limits. We confirm it for your address rather than guessing.
My house is on Fore Street. Is that different? Yes, considerably. Protected frontages mean a full application and a design that answers to the character appraisal. It also means the council is receptive to work that improves the street, which is worth using rather than fighting.
Am I in a flood zone? Parts of N9 and N18 are. The government’s postcode checker will tell you in a minute, and it changes how the ground floor is detailed as well as what gets approved. We check it on every Edmonton survey.
I want to convert to an HMO — what do I need? Planning permission, everywhere in Enfield, regardless of conservation area status. Get that established before you buy, not after.
How quickly can you start? If the work is permitted development, quickly — which in Edmonton it often is. If an application is needed, add Enfield’s determination period and the preparation before it. We give you a date you can plan around.
