Do I Need Planning Permission for a Garden Wall?
IT DEPENDS
Garden walls up to 1 metre high on a boundary with a highway and up to 2 metres high elsewhere are usually permitted development. Taller walls, walls in conservation areas over certain heights, and walls on listed building curtilage require planning permission or listed building consent.
Keep reading for the full rules.
Building or replacing a garden wall is usually permitted development for most homeowners. The height limits are straightforward: 1 metre adjacent to a highway and 2 metres elsewhere. Conservation areas and listed buildings have additional restrictions. Building regulations are generally not required for garden walls, but structural advice is recommended for walls over 1.5 metres.
Permitted Development Rules by Region
Permitted Development Rules — England
- ✓A wall on any boundary of a dwellinghouse is permitted development if it does not exceed 1 metre in height where it is adjacent to a highway (including a footpath or bridleway).
- ✓A wall elsewhere on the boundary (not adjacent to a highway) is permitted development if it does not exceed 2 metres in height.
- ✓In a conservation area, removing a wall that is within the curtilage of a listed building or that forms part of the character of the conservation area may require conservation area consent or listed building consent — check with your LPA.
- ✓Any gate, fence, wall or other means of enclosure adjacent to a highway within a conservation area may require permission if it would exceed 1 metre in height.
- ✓Article 4 Directions can remove PD rights for walls and means of enclosure in sensitive areas.
Size & Position Limits (England)
| Requirement | Limit / Rule |
|---|---|
| Max height adjacent to highway | 1m — above this requires planning permission |
| Max height elsewhere | 2m — above this requires planning permission |
| Conservation areas (highway boundary) | Walls over 1m may need permission if visible from highway |
| Listed buildings | Listed building consent required for walls within curtilage |
| Shared/party boundary | Party Wall Act may apply for walls on or astride the boundary |
When Do You Need Planning Permission?
Even if your project is usually permitted development, planning permission is required in these circumstances:
- ✗The wall would be higher than 1 metre on any boundary with a highway (road, footpath, or bridleway).
- ✗The wall would be higher than 2 metres on any other boundary.
- ✗The wall is in a conservation area and would be visible from a highway.
- ✗The wall is within the curtilage of a listed building — listed building consent is required.
- ✗Your council has an Article 4 Direction that removes PD rights for walls in your area.
What Happens If You Build Without Permission?
A wall built higher than the PD limits or in a conservation area without permission can attract enforcement action. Councils can require the wall to be lowered or removed. The 4-year enforcement time limit applies for dwellinghouse works. In conservation areas, enforcement can also be taken for removing a wall that required conservation area consent.
Enforcement notices: Your council can issue an enforcement notice requiring you to stop the work, remove it, or restore the land to its original condition. You have a right of appeal against an enforcement notice.
Retrospective applications: If you have already carried out work that required planning permission, you can submit a retrospective planning application. If approved, this regularises the work. If refused, you may be required to remove it.
Time limits: For dwelling houses, the council generally has 4 years to take enforcement action for most types of work. For breaches of planning conditions, the time limit is 10 years. There is no time limit for listed building enforcement.
