Garage Conversion Planning Permission
Practical advice on whether your garage conversion needs planning permission before you start work.
A garage conversion can be one of the simplest ways to create extra space without building a large extension. Homeowners often convert garages into offices, playrooms, bedrooms, gyms, utility rooms, hobby rooms or additional family space.
​
Some garage conversions may not need a full planning application, but that does not always mean you can simply start work. Planning permission, a lawful development certificate or supporting drawings may still be needed depending on the property, the location and the proposed changes.
​
Planning issues can arise where:
​
-
The garage door is being removed or infilled
-
New windows or doors are proposed
-
The front appearance of the house is changing
-
The property is on a newer estate with planning restrictions
-
There are parking conditions attached to the house
-
The garage is detached or separate from the main house
-
The property is in a conservation area
-
The conversion forms part of a larger project
-
The council needs drawings to confirm the planning position
​
​
Ask PAS About Garage Conversion Plans and Drawings
The drawings are often the most important part of the process. Even where a garage conversion is straightforward, clear plans help explain the proposal properly and avoid confusion.
​
Planning Application Services (PAS) can prepare garage conversion plans and drawings for homeowners who need to show:
​
-
What the garage looks like now
-
How the garage connects to the house
-
What the new room will be used for
-
How the garage door will be replaced or altered
-
Where new walls, windows or doors will go
-
Whether the outside of the house will change
-
How the proposal affects the driveway, parking or access
-
Whether the project is suitable for planning permission or a lawful development certificate
​
PAS can prepare drawings for:
​
-
Integral garage conversions
-
Attached garage conversions
-
Detached garage conversions
-
Part garage conversions
-
Double garage conversions
-
Garage conversions with new front windows
-
Garage conversions with new side or rear doors
-
Garage conversions linked to extension projects
-
Garage conversions into bedrooms, offices, gyms, playrooms or utility spaces
​
​
What a Garage Conversion Planning Package May Include
The exact drawings depend on the project, but a typical package may include:
​
-
Existing floor plans
-
Proposed floor plans
-
Existing elevations
-
Proposed elevations
-

-
Photos of the existing garage and frontage
-

​
A clear drawing package helps the council understand the proposal and gives the homeowner a proper record of what has been applied for.
