Planning Permission for Extensions

Looking to install an extension in your Leeds, Harrogate or West Yorkshire home? There are many factors that influence extension planning permission but the good news is that extensions are classed as Permitted Development, this means that most extensions won’t require permission. If you are unsure if your extension fits these criteria, please check with your local planning office. Your local office will be able to fully advise you, but there are a variety of reasons why you may need extension planning permission.
