Architectural Drawings in Southgate | Fixed-Fee Plans

No Article 4 Direction covers Enfield, which keeps the Southgate permitted-development route open on unlisted houses. You cannot design for Southgate without accounting for the fact that it is 1930s semi-detached, Edwardian. A N14 property inside Bush Hill Park loses part of its permitted development and generally goes to Enfield Council in full. Conservation status is checked against the Southgate address before design.

That mapping of Article 4 directions across Southgate happens before design, which is what keeps the Enfield Council route predictable. What the Southgate building allows is established first; what Enfield Council allows, second. The borough policy layer over every N14 address is set out on Enfield planning. The Southgate survey then carries into building regulations drawings in Southgate if the project runs on to construction.

Before Enfield Council determines anything, London Borough of Enfield has to validate the Southgate submission — one to two weeks, longer if a plan is missing. The Southgate job starts with a laser survey, not a sketch.

Statutory periods: 8 weeks from validation for a householder application, 13 weeks for a major scheme, 6 weeks for prior approval with a 21 days neighbour consultation, and 5 weeks for a full plans building control submission. A party structure notice requires one month notice and two months where excavation is involved.

Once Enfield Council registers the Southgate case, the officer site visit usually follows within a fortnight. Output for Southgate: dimensioned PDFs at the scales the authority specifies.

A N14 objection about light or overlooking carries more weight than one about taste. The Southgate survey includes the boundary line and neighbouring window positions.

On Southgate stock the party wall stage is routine and worth timetabling. Once consent is granted, loft conversion drawings follows for the N14 property.

Southgate is characterised by 1930s semi-detached, edwardian villas, concentrated across N14 in the Southgate area. N14 construction is 1930s semi-detached-led, and the survey establishes what it carries. For Southgate owners this matters because edwardian back additions here are often out of plumb, which matters once a steel goes in. That is the Southgate constraint Enfield Council will look for. Enfield Council judges massing against the established Southgate rhythm — the eaves and ridge lines running past Southgate Tube.

Basement work at a Southgate address is judged on amenity, drainage and structure. If the N14 job later needs house extension drawings for N14 properties or planning permission, the existing drawings already carry the measurements.

Streets and landmarks we survey around Southgate

• Grovelands Park — front-to-back level changes that drive the Grovelands Park section drawings.
• Cullands Grove — terraced rear elevations — the Cullands Grove party wall position is drawn first.
• Palmers Green — side returns where the 45-degree amenity test decides how far a Palmers Green extension goes.
• Winchmore Hill — front-to-back level changes that drive the Winchmore Hill section drawings.
• Brunswick Park — roof profiles that set the ridge datum Enfield Council measures a Brunswick Park dormer against.
• Arnos Grove — closet wings that change how a rear extension meets the Arnos Grove back addition.
• Southgate Tube — massing on adjoining N14 plots is tested against it.
• Ashmole School — Enfield Council weighs N14 sightlines to it in the character assessment.
• Ashmole Academy — schemes in view of it attract closer officer scrutiny.
• Southgate College — schemes in view of it attract closer officer scrutiny.
• Oak Hill College — a Southgate roof extension is judged against the datum it sets.

Getting to a Southgate survey

Surveyors travel to N14 addresses from the studio; the nearest stations are Southgate, Oakwood, Arnos Grove. Appointments are booked in Southgate on weekdays and Saturdays, and the measured survey of a standard 1930s semi-detached takes two to three hours.

Where Southgate sits

Southgate lies 8 miles (13 km) north of Charing Cross, on Ordnance Survey grid reference TQ296942. We draw the Southgate location and block plans from that reference, which is what Enfield Council validates against. Source.

Practical detail for a Southgate submission: Southgate and Oakwood and Arnos Grove cover the N14 area; the Southgate post town is LONDON; dialling code 020; listed buildings around Southgate include Grade II* Southgate tube station and Grade II Arnoside House and Essex House.

Southgate postcode coverage

Coverage runs across N14 (Southgate), shared with Oakwood — and Enfield Council validates against the address, so the district line matters more than the street name.

Statutory fees for N14 addresses are payable to London Borough of Enfield on the day it is lodged. London planning approval-rate dataset · Enfield planning · architectural drawings in London · architectural drawings in Finchley.

A chartered technologist surveys the Southgate property and signs the drawings — the same person, start to finish. We would rather spend on Enfield Council advice than lose a Southgate decision and resubmit.

Drawings are produced by chartered members of the Chartered Institute of Architectural Technologists (MCIAT), the professional body for technical design and building-regulations competence. First-time approval across our London caseload is 98%. Statutory fees shown are those in force in England in 2026 under the Town and Country Planning (Fees for Applications) Regulations.
