The 2014 standards are still the adopted standards
Enfield is in an awkward planning transition. A replacement Local Plan has reached examination, but it has not been adopted.
The council’s adopted plans page still says that applications are determined using the Core Strategy adopted in November 2010, the Development Management Document adopted in November 2014, area-based documents and the London Plan. The replacement plan was submitted to the Secretary of State on 6 August 2024. Its examination continued through the Inspector’s post-hearing letter of 15 June 2026 and the council’s response of 29 June 2026.
That distinction matters because search results expose both sets of extension figures. The policies in the Regulation 19 plan and later proposed modifications are not yet the adopted yardstick. For a current application, begin with the 2014 DMD and then check whether an area plan, neighbourhood plan or Article 4 direction also applies.
Three metres, four metres, 45 degrees, then 30
Policy DMD11 contains unusually specific rear-extension standards.
For a single-storey rear extension assessed under the policy:
- the depth must not exceed 3 metres beyond the original rear wall of a terraced or semi-detached property, or 4 metres for a detached dwelling;
- a flat roof must not exceed 3 metres at the eaves, with an allowance of 3.3 to 3.5 metres to the top of a parapet;
- a pitched roof must not exceed 4 metres at the ridge and 3 metres at the eaves; and
- the extension must not cross a line taken at 45 degrees from the midpoint of the nearest original ground-floor window of an adjacent property, unless a common alignment of rear extensions is secured.
A first-floor extension uses a tighter 30-degree line from the midpoint of the nearest original first-floor window.
These are planning standards for proposals that require assessment under the policy. They are not the excavation tests in section 6 of the Party Wall etc. Act, and they do not establish whether a shared wall or boundary belongs to either owner.
A one-metre side gap is a planning rule, not an Act exemption
The same adopted document deals separately with roof and side extensions.
DMD13 says a roof dormer should normally be inset 500 to 750 millimetres from the eaves, ridge and edges of the roof. DMD14 says a side extension should maintain at least one metre from the boundary with the adjoining property. A larger distance may be required where plot size, the streetscene or residential amenity calls for it.
That one-metre gap is sometimes misunderstood. Keeping a side extension one metre from the boundary does not automatically take its foundations outside the Act. The statutory excavation question still turns on how close and how deep the excavation will be relative to the neighbouring building and its foundations.
Every householder basement needs a five-stage assessment
Enfield has no borough-wide policy fixing a maximum basement footprint. It does, however, have a demanding validation requirement.
The current householder validation checklist, updated 6 November 2023, requires a Basement Impact Assessment for a new basement, an extension to a basement or other extensive groundworks. It must cover:
- screening;
- scoping;
- site investigation and study;
- impact assessment; and
- review and decision making.
The document must address onsite geology, the depth of groundwater relative to the basement, groundwater flow routes, predicted effects on neighbouring property and the measures proposed to reduce groundwater and flooding effects. A non-technical summary is required. Where the works are to a listed building or immediately beside one, the assessment must be peer-reviewed by a Conservation Accredited Engineer.
That assessment is planning evidence. It is not a Party Wall notice, consent or award. Receiving planning permission and satisfying the validation list do not remove a building owner’s separate obligations where the Act applies.
Hadley Wood does not have an Enfield 50 per cent cap
Hadley Wood has a made neighbourhood plan. The Hadley Wood Neighbourhood Plan 2022 to 2039 became part of the development plan on 22 November 2023.
Its flood policies are substantive. Policy HW-8 requires development not to increase fluvial, surface-water, groundwater or sewer flood risk, and requires flood risk to be assessed with sustainable drainage. The supporting text records groundwater flooding in Hadley Wood and says basement development should be accompanied by a groundwater flood-risk assessment so that effects on neighbouring development are understood.
But the document also contains a trap for anyone extracting numbers without reading their status. Paragraph 5.41 says that Enfield has no basement guidance and strongly encourages applicants to follow Camden’s guidance, including its 50 per cent figures for the host dwelling and garden.
Those are not Enfield limits. They are a recommendation in the supporting text of the Hadley Wood plan, borrowed from another borough. An Enfield page should not convert them into a borough-wide policy cap.
Fifteen conservation areas have some Article 4 control
Enfield lists 22 conservation areas. Its Article 4 records identify directions affecting specified addresses in 15 of them.
The directions are not interchangeable. They cover different properties, elevations and classes of work, so an address must be checked against the direction and its map.
Enfield Town provides the clearest example. Its 2017 Article 4(1) Direction took effect on 8 January 2018. For listed addresses it withdraws specified rights where the work fronts a relevant location, including certain enlargements and alterations, roof additions, porches, hard surfaces, chimneys, boundary treatments and exterior painting. The direction expressly cancelled the 1978 direction and the portion of the 2006 borough direction that applied to Enfield Town.
An older Enfield Town direction found in search may therefore describe a control that has been replaced. And being inside one of the 15 conservation areas does not by itself show that a particular rear extension is controlled: the address, affected elevation and class of work all matter.
Second only to Newham for terraced-property numbers
At 31 March 2025 the Enfield all-property row in the Valuation Office Agency’s table CTSOP3.0 recorded 128,390 domestic properties:
- 52,710 flats or maisonettes;
- 47,910 terraced houses;
- 21,510 semi-detached houses;
- 4,550 detached houses;
- 1,440 bungalows; and
- 150 annexes, 30 caravans, houseboats or mobile homes, and 100 properties of unknown type.
Comparing the same table across the 33 London boroughs, Enfield’s 47,910 terraced properties are the second-highest absolute count in London, behind Newham on 50,910. Terraced and semi-detached properties together total 69,420, just over 54 per cent of the CTSOP3.0 total.
The figures describe property types, not legal party-wall status. They do not establish that a particular flank wall is shared, and a flat may have a party structure in a floor or ceiling rather than a wall. They do show why the precise property form belongs in the job brief.
The separate build-period table CTSOP4.1 in the same Valuation Office Agency release shows that Enfield’s largest band is 1930 to 1939, with 36,260 properties. Its recorded pre-1940 bands total 75,130, or about 58.5 per cent of that table’s 128,340-property total. The CTSOP3.0 and CTSOP4.1 totals differ by 50, so the denominators are not interchangeable. All these counts are rounded to the nearest ten and count properties on the Council Tax list rather than households.
The statutory excavation test is separate
The official Party Wall Act explanatory booklet states the section 6 tests independently of Enfield’s planning policies.
For the three-metre test, excavation must be within three metres of the neighbouring building and extend below the bottom of its foundations. For the six-metre test, the excavation must fall within six metres and meet the statutory 45-degree plane drawn from the bottom of the neighbour’s foundations.
Neither Enfield’s three-metre extension depth nor its 45-degree daylight line is a substitute for those tests. They happen to use similar numbers for different legal and technical questions. The guide to whether a Party Wall surveyor is needed explains the distinction before any appointment is considered.
Explain the property and proposed work
Provide:
- the full property address;
- whether the property is terraced, semi-detached, detached, a bungalow or a flat;
- which walls, floors or ceilings appear to be shared, and with whom;
- whether the property lies in a conservation area or the Hadley Wood neighbourhood-plan area;
- whether an Article 4 direction covers the address and affected elevation;
- the depth, height and position of any rear, side or roof extension;
- whether excavation or a basement is proposed, how deep it will be and how close it comes to neighbouring buildings;
- what is known about the neighbour’s foundation depth;
- whether a Basement Impact Assessment, groundwater assessment or structural information has been prepared;
- whether you are carrying out work or responding to a neighbour’s work;
- drawings where available;
- notices, responses and correspondence already exchanged; and
- known dates and access constraints.
Compare the proposed appointment
Each quote should explain who would appoint the surveyor and the work included. That may involve reviewing drawings, notices and excavation information, inspections, a schedule of condition, preparation of an award, liaison with another surveyor or later visits.
The Party Wall surveyor guide explains when an appointment may be needed, while the Party Wall surveyor cost guide explains the factors affecting a proposed fee. Nearby coverage includes Party Wall surveyors for Barnet properties and the wider Party Wall surveyor north London guide.
What happens after you post
Your verified enquiry is available to the administrator for review. Invitations are not currently available. In a later comparison service, a participating surveyor would receive only the outward postcode and a restricted brief before an authorised introduction.
When comparison is available, complete quotes and the surveyor’s private profile can be shown on your private customer page. Availability varies, so a request may receive several quotes, one, or none. Submission does not guarantee an invitation, quote or introduction.
If introductions are available and the administrator records your chosen introduction, only that surveyor receives your full contact and property details. FindTheSurveyor charges neither party a fee. You pay the professional fee directly to the surveyor.
