Will I need planning permission for a cellar conversion

A cellar conversion is a change of use from a storage area to a habitable living space and does not usually require planning permission. If you had to carry out major excavations to the existing cellar floor you may be deemed to be increasing the size of your property (not unlike an extension). Most extensions and alterations can however be undertaken under Permitted Development – rights that were introduced on the 1st October 2008 (use the link provided on this website to view what is now allowable under Permitted Development).

We would always recommend that you discuss any alternations to your property with your local planning office to check whether or not planning permission is required. We would also recommend that you check your deeds to ensure that there are no covenants placing restrictions on your property.
