Prefer to talk it through?
Does a Richmond garage conversion need planning permission?
Often the answer turns on two things: whether the garage is integral or detached, and whether a planning condition or an Article 4 direction takes away the usual freedoms. Our planning permission guide for garage conversions walks through the tests.
For Richmond, 85 conservation-area entries sit on the national register (our analysis of MHCLG Planning Data Platform conservation-area and article-4-direction datasets). Check your TW9 road on Richmond Council's conservation area map, or in the government's conservation-area dataset, before you decide anything, and read our entry on the Article 4 direction if the council has removed permitted development rights locally.
A certificate instead of an application
Some owners ask the council to confirm in writing that a conversion is lawful instead of applying for permission. Richmond decided 917 certificates of lawful development in the eight quarters to 2026 Q2 (our analysis of MHCLG planning application statistics, table PS1). Our lawful development certificate entry explains what the certificate does and does not cover.

How Richmond handles householder applications
If your garage conversion does need an application, it is decided as a householder case. In the four quarters to 2026 Q2, 83% of Richmond's householder decisions were grants (our analysis of MHCLG planning application statistics, table PS2). That is a record of past decisions in the borough, not a forecast for your address.
For an application that is not major development, the Town and Country Planning (Development Management Procedure) Order 2015 sets a decision period of 8 weeks, counted from the day after the council receives it. The council's statutory fee for a householder application has been £548 since 1 April 2026, paid to the council and separate from our fee.
Building Regulations come after the layout is settled
A converted garage must still meet Building Regulations for structure, thermal performance, fire safety and ventilation, whichever planning route you take. Under regulation 14A of the Building Regulations 2010 the authority must notify the outcome of a full plans application within five weeks of receipt, unless you agree a longer period in writing.
We draw the regulations set to match the planning set, so the wall build-up and floor insulation you see on one sheet are the ones on the other. See our Building Regulations drawings in Richmond.

Fixed fees for a Richmond garage set
Garage conversion drawings start from £645. Where an Article 4 direction applies to your property, the fee starts from £745. The garage conversion cost guide covers build costs, and the pricing page lists every fixed fee. Our garage conversion drawings service page shows what is in the set.
