Do You Need Planning Permission to Convert a Garage?

It’s important to know the rules and regulations involved in converting a garage into an inhabited space. The need for permission to convert a garage depends on your specific project and circumstances.

The Planning Portal governs the UK’s rules and regulations for garage conversions. It outlines these specific guidelines:

Permitted Development Rights

In the UK, garage conversions are often covered by Permitted Development Rights (PDR). This is a term that refers to rules and regulations which allow homeowners to make changes to their property without needing formal planning permission. The PDR guidelines make it easy to convert a garage into an extra room. However, you will need to follow certain conditions.

  • Size restrictions: A detached house cannot exceed 30 square metres of floor space, or a semi-detached or attached home 40 square metres. This includes all previous outbuildings and additions.
  • Exterior changes: While most alterations to the interior are allowed, significant exterior alterations, such as changing the roofline, adding windows, or doors may require a planning permit.
  • Conservation Areas and Listed Buildings: Garage conversion permissions are more likely required if your home is in a conservation zone or a listed property.

Building Regulations

Even if you are converting your garage under permitted development, in the UK you must still adhere to the building regulations. These ensure that the conversion is safe, structurally sound, and meets insulation standards. Silverfern Developments are Exeter Builders who can help when you need Exeter Builders.

Party Wall Agreement

The Party Wall Act of 1996 may apply if your garage shares a wall with a neighbouring property. The Act requires that you notify your neighbours of the proposed work and possibly obtain their consent, particularly if it involves structural changes.

Use of the Space

Be sure that your new garage use is compliant with the planning regulations. Converting it into an office or gym, for example, is generally acceptable. If you want to convert it into an independent dwelling, there may be different requirements.
