Southgate (N14) is anchored by Southgate Green, a historic green ringed by Georgian and Victorian houses and more than thirty listed structures, with Edwardian and interwar semis on the surrounding streets where most of our extension and loft work sits.

Because the Article 4(2) directions made in 2009 remove permitted-development rights on frontages inside the conservation area, we check the mapped boundary and listing status before advising whether a scheme is genuinely PD or needs a full application with heritage justification.

Planning in Southgate Green (N14): what to know before you apply

Most Southgate extensions run as householder applications to Enfield, with a heritage statement where the property is inside the Southgate Green Conservation Area. The 2009 Article 4(2) directions remove PD rights on street-facing elevations, and listed-building consent can be required near the green, so we confirm boundary and listing status first.

New Build Drawings for Southgate Green (N14) homes: the package and the process

A new dwelling is a full application rather than a householder one, and the drawing set reflects that: site layout with levels and boundaries, floor plans and elevations for the new building, sections showing how it sits in the ground, and street-scene elevations placing it against what is already there.

Two packages follow the approval — the planning set and the construction set — and they have to stay in step. Foundation design, drainage strategy, thermal performance and fire strategy are drawn for Building Control against the same geometry that was granted permission, so the built house matches the approved one.

An infill plot is designed against its neighbours. Plot width, the building line either side, and the ridge heights next door set what the new house can be — and on a tight urban site those constraints usually shape the design more than the brief does.

Is my plot suitable for a new build in London?

A feasibility assessment looks at plot size and shape, access, existing boundary conditions, relevant planning policy for the borough, and the likely impact of a new dwelling on neighbouring properties before any design work begins. Infill plots — a gap between existing buildings on a street — and backland plots — a garden or yard site behind existing houses, reached by a shared access — each raise different issues: infill schemes are usually judged on how well they match the scale, spacing and character of the street, while backland schemes are judged heavily on overlooking, garden loss for neighbours, and whether the access arrangement is acceptable. A feasibility study gives an honest view of whether a scheme is likely to succeed before you commit to full drawings.

What does pre-application advice add to a new build project?

Pre-application advice is a formal, paid process most London boroughs offer, where planning officers give written feedback on a proposed scheme before a full application is submitted. For a new build — where the principle of development itself is often the main issue, not just the design details — this feedback can be invaluable: it surfaces concerns around density, massing, daylight and sunlight or heritage context early enough to be addressed in the drawings, rather than discovered for the first time as a refusal reason months into a full application. We prepare and submit pre-application enquiries as part of the new build service where it is likely to strengthen the eventual planning application.

How do daylight, sunlight and overlooking affect a new build design?

London boroughs assess new dwellings against their effect on the daylight and sunlight reaching neighbouring homes and gardens, commonly using the 45-degree rule as an initial check on a proposal's massing and position relative to neighbouring windows, alongside more detailed daylight and sunlight assessment on sensitive sites. Overlooking and loss of privacy from new windows, upper floors or roof terraces are assessed similarly, and often shape decisions on window placement, floor-to-floor heights and the overall footprint and massing of the new building. Designing with these constraints from the earliest sketch stage, rather than adjusting for them after a refusal, is one of the main advantages of instructing feasibility and pre-application work before a full planning set.

FAQ

New Build Drawings in Southgate Green N14 — FAQs

How much do new build drawings cost in London?+
New build drawings start from £2,500 for feasibility and a full planning drawing set on a straightforward infill or backland plot, with building regulations and structural drawings quoted separately once the planning design is agreed.
Can any garden or backland plot be built on in London?+
Not necessarily — backland and garden plots are assessed on access, overlooking, loss of garden amenity for neighbours and borough policy, and a feasibility assessment gives an honest early view of whether a scheme is likely to be supported.
Do I need pre-application advice before a full new build application?+
It is not mandatory, but for a new dwelling — where the principle of development is often the main issue — pre-application advice can surface concerns early enough to address them in the design, reducing the risk of refusal.
Do you handle building regulations and structural drawings for a new build, or only planning?+
Both — the full new build service covers planning, building regulations and structural drawings from one in-house team, so the design stays consistent from feasibility through to construction-ready drawings.
How long does a new build project take from feasibility to planning permission?+
This varies with site complexity and whether pre-application advice is sought, but a full planning application is determined within the statutory period the borough applies to the application type, once submitted via the Planning Portal.
Do I need planning permission for a loft or extension in Enfield?+
Across Edmonton, Palmers Green and Enfield, the borough's interwar semis usually keep permitted development rights for rear extensions and hip-to-gable or dormer lofts, so a full application isn't always needed. Conservation areas such as Bush Hill Park and Winchmore Hill, and green-belt land to the north, remove or restrict those rights. We check your address first and confirm permitted development with a Lawful Development Certificate where it applies.
How does green-belt land affect my Enfield project?+
On green-belt properties toward the borough's northern edge, extensions are assessed against strict limits on disproportionate additions to the original dwelling. It does not rule out an extension, but scale and siting matter and the case must be evidenced carefully. We confirm whether your property is green belt and design a scheme that stays within policy.
What does Enfield's borough-wide HMO Article 4 direction affect?+
Enfield applies a borough-wide Article 4 direction removing permitted development rights for change of use to an HMO (C3 to C4), so a conversion to a house in multiple occupation needs a full application anywhere in the borough. It doesn't affect a standard family extension, but we confirm whether it applies to your intended use before advising.
How long does Enfield Council take to decide?+
Enfield determines most householder applications within the statutory eight-week period once validated; conservation and green-belt cases can involve additional consultation. We prepare Enfield submissions to the council's validation checklist to avoid the drawing queries that cause most delays.
How much do planning drawings cost in Enfield?+
We agree a fixed fee before starting, usually around 30% below an architect's fee for the same council-accepted drawings, with free redraws until Enfield approves. A suburban loft and a green-belt or conservation case differ in the evidence required, so we quote once we understand your address and project rather than by the hour.
