Single and double garage conversions in Sutton
A double garage gives Sutton homeowners a large footprint to turn into a bedroom, office or family room, and the council still needs scaled drawings of it. DrawingsDirect draws single and double garage conversions across Sutton, Cheam and Hackbridge from £645, or £745 with an Article 4 direction.

Prefer to talk it through?
Why a double garage is a bigger drawing job than a single
Two bays usually mean a wider door opening to infill, a longer wall to insulate and a bigger floor area to bring up to modern thermal standards. The drawings show each of those details, so a builder can price the work and the council can see what changes from the street.
The garage door is the part neighbours notice most. We draw the replacement wall and window as elevations, so the new front fits the rest of the house.
Planning, or a lawful development certificate?
Whether a Sutton garage conversion needs a planning application depends on the original permission, any condition about keeping the garage for parking and whether an Article 4 direction applies to your road. Our guide to planning permission for a garage conversion sets out the questions to ask.
Where permission is not needed, a certificate gives you written proof that the use is lawful. Sutton decided 643 certificates of lawful development across the eight quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS1). Our lawful development certificate entry explains the process.

Sutton's decision record on householder applications
Sutton granted 92% of its householder decisions in the four quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS2). Treat that as a picture of the borough's past decisions. It says nothing about a particular address.
Sutton shows 15 conservation-area entries on the national register (our analysis of MHCLG Planning Data Platform conservation-area and article-4-direction datasets). Look up your street on the government conservation-area dataset, confirm it against the map on Sutton Council's website, and read our conservation area entry if yours is listed.
Timings and fees you will meet along the way
An application that is not major development carries a decision period of 8 weeks from the day after the council receives it. The householder application fee is £548 from 1 April 2026, payable to the council.
Building Regulations run on their own clock. For a full plans application the authority must give its outcome within five weeks of receipt, unless a longer period is agreed in writing.
