Home extensions and renovations Converting a garage

You don't always need planning permission to convert a garage

Converting a garage or outbuilding can provide extra space with less hassle than building an extension. Most of us don’t actually park our cars in the garage, so it’s often wasted space. 

You don’t always need planning permission for a garage conversion – see our advice on and check with your local authority. If it is required it's normally a straightforward process.

You must still make sure that you comply with the building regulations. See our guide to building regulations for more information.

The downside of converting a garage is that it can be difficult to create access through from the house. It may also affect the value of your home as in some areas buyers may prefer a garage to an extra room.
