1 Planning permission-You usually only need to apply for planning permission to convert a garage when you intend to extend the actual size of the garage. 2  However, check with your local authority as the precise rules do differ. Double garage-You may either convert the whole area, or just the nearest side to your house. 2  If you convert it all, you can expect to add around 300 square feet of floor space to your home. 3  Tandem garage-As before, converting only the back will leave you with the best of both worlds.
