Oak Framed Garage Planning Permission
In many cases you won't need planning permission for an oak framed garage.
A detached garage is usually treated as an outbuilding and can be built under permitted development, as long as it stays within set limits on size, height and position.
The main thing that changes the answer is a room above, which will normally need full planning permission. Here's what to check before you build.


When You Don't Need Planning Permission
A detached oak framed garage is generally permitted development, meaning no planning application is needed, if all of the following apply:
✔ It sits behind the front wall (principal elevation) of the house, not forward of it
✔ It's single storey, with eaves no higher than 2.5m and an overall height no more than 4m for a dual-pitched roof, or 3m for any other roof
✔ Anything within 2m of a boundary is no more than 2.5m tall overall
✔ Together with other outbuildings, it covers no more than half the land around the original house
✔ It's used for a purpose incidental to the house, such as parking, storage or a workshop, and not as separate living accommodation
Stay inside all of those and you can usually build without applying.
When You Do Need Planning Permission
You'll normally need full planning permission if:
✔ The garage has a room above. A room above makes it two storey, which falls outside permitted development for outbuildings, so it will almost always need planning permission. This is the single most common trigger for oak garages.
✔ It's used for sleeping or as a self-contained annexe. The moment it becomes living accommodation rather than incidental space, permitted development no longer applies.
✔ It sits forward of the front of the house, or breaches the height or coverage limits above.
✔ Your property is on designated land, such as a conservation area, National Park, Area of Outstanding Natural Beauty or the grounds of a listed building, where the rules are tighter and side or larger outbuildings often need permission. A listed building will also need listed building consent.
✔ Permitted development has been removed from your property by an Article 4 direction, which some councils apply in specific areas.
Permitted development rights also don't apply to flats or maisonettes.


Building Regulations Are Separate
Planning permission and building regulations are two different things.
Even a garage that doesn't need planning permission may still need building regulations approval, particularly if it has a room above, contains habitable space or exceeds the exempt floor area.
If you're adding a usable room above, budget for building regulations either way.
