How Big Can a Garage Be Without Planning Permission UK?
Building a garage without planning permission is possible under permitted development rights, but there are strict size and location restrictions. The maximum size allowed depends on factors such as height, footprint and proximity to boundaries. Understanding these limits ensures compliance with UK planning regulations and avoids the need for an application.
Maximum Garage Size Under Permitted Development
A garage can be built without planning permission if it meets certain conditions. It must be single-storey with a maximum eaves height of 2.5 metres and an overall height of 4 metres if it has a pitched roof, or 3 metres for other roof types. The garage must not exceed half the land surrounding the original house and cannot be built in front of the property’s principal elevation. If located within 2 metres of a boundary, the height must not exceed 2.5 metres.
When PlanninPermission is Required
Planning permission is needed if the garage exceeds the permitted size limits or is intended for residential use rather than storage or parking. Larger garages, especially those used as workshops or home offices, may require approval. Properties in conservation areas, national parks or listed buildings often have additional restrictions, requiring planning permission regardless of size.
Other Regulations to Consider
Even if planning permission is not required, the garage must comply with building regulations if it is over 30 square metres or attached to the house. Regulations apply to structural integrity, fire safety, ventilation and insulation. Checking with the local planning authority before starting construction ensures the project meets all legal requirements.
Final Considerations
A well-planned garage can add valuable storage and parking space without the need for planning permission, as long as it stays within the permitted size limits. For homeowners looking to build a larger structure, applying for planning permission may be necessary, but understanding the regulations in advance can help avoid unexpected issues.
