For Sutton property owners: MCIAT chartered extension plans. Sutton Council is the decision-maker for Sutton; the SM1 district sets the constraints.

What is house extension drawings in Sutton?

House Extension Drawings in Sutton are survey-based Sutton drawings for a rear, side or wrap-around extension in SM1. In the SM1 postcode area they are assessed by Sutton Council against the Sutton Local Plan, and they fix the Sutton depth against permitted-development limits, answer the 45-degree amenity test Sutton Council applies, and locate the party wall on the edwardian terraces.

Architectural detail on a London period property — house extensions in Sutton
Sutton Council context

Do I need house extension drawings in Sutton?

No Article 4 Direction covers Sutton, which keeps the Sutton permitted-development route open on unlisted houses. The character of Sutton is the yardstick a Sutton Council officer measures a scheme against: Edwardian centre, 1930s residential. A Sutton address in Sutton Central or Carshalton Village loses part of its permitted development, so we usually take the SM1 scheme to Sutton Council as a full application from the outset. That boundary is verified for the SM1 property at the outset.

The Sutton Article 4 position is established at survey, before design. A SM1 survey answers most of it — where the edwardian terraces allows the rear wall to go. The borough policy layer over every SM1 address is set out on Sutton planning. The Sutton survey then carries into architectural drawings in Sutton if the project runs on to construction.

Timeline

How long does Sutton Council take to decide?

Expect one to two weeks of London Borough of Sutton validation on a Sutton submission before the statutory period even begins. The Sutton 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.

The SM1 case officer consults neighbours and visits before drafting a report. We format the Sutton set exactly as Sutton Council wants to receive it.

Objections on a Sutton case usually come from the immediate neighbours, not the wider SM1 area. A Sutton survey takes two to three hours and needs access to every room.

Party wall procedure runs alongside the Sutton application, not after it. Once consent is granted, planning permission follows for the SM1 property.

Local building fabric

What Sutton's housing stock means for your plans

Sutton is characterised by edwardian terraces, 1930s semi-detached, concentrated across SM1 in the Sutton area. The edwardian terraces across Sutton decides how a scheme is built, not just how it looks. Applied to SM1 property: edwardian plots here are wider, so a wraparound picking up both the side return and the rear is normally achievable within the 4 m detached / 3 m attached limits. It is why the Sutton existing set is measured, not traced. A Sutton proposal that breaks the prevailing eaves line invites a refusal.

No borough-specific basement policy applies in Sutton, so subterranean work at a Sutton address is judged on amenity, drainage and structural grounds. Survey once, use it for every SM1 submission that follows.

Your SM1 technologist

MCIAT chartered technologists working across Sutton

Drawings for Sutton are issued under MCIAT charter, which is the technical design and construction-detailing qualification rather than an RIBA registration. Marginal SM1 sites get checked with Sutton Council first; a refusal costs far more than the advice fee.

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. Confirm your local authority at gov.uk and submission requirements on the Planning Portal. Studio: 71–75 Shelton Street, London WC2H 9JQ.

A short call about the Sutton property is usually enough to scope the job. This Sutton page was reviewed in August 2026.
