From parking space to living space
A converted garage in TW1 usually becomes a home office, a bedroom or a playroom beside the kitchen. Each calls for different drawings of wall build-up, windows and heating, which is why we ask what the room is for before drawing anything.
Twickenham sits in Richmond's planning area
Twickenham applications go to the London Borough of Richmond upon Thames, so the borough's figures are the ones that apply. Over the four quarters to 2026 Q2 it granted 83% of its householder decisions (our analysis of MHCLG planning application statistics, table PS2). Past decisions give context, and they never promise an outcome for yours.
For the same borough, the national register carries 85 conservation-area entries (our analysis of MHCLG Planning Data Platform conservation-area and article-4-direction datasets). Check whether your road is one on Richmond's own conservation area map, with the conservation-area dataset and our conservation area entry.

Asking the council to confirm a conversion is lawful
A lawful development certificate is the alternative to a planning application when you believe the conversion needs none. Richmond decided 917 of them over the eight quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS1), which shows how routine the request is. Our certificate entry explains the steps.
How long each stage takes, and what the council charges
A decision on an application that is not major development is due within 8 weeks, counted from the day after receipt. The householder fee is £548 from 1 April 2026, paid to the council.
For Building Regulations, a full plans application must get an outcome within five weeks of receipt unless a longer period is agreed in writing. Our guide to garage conversion costs in London puts these council charges beside the build budget.
