Do I need planning permission to convert my garage into additional living accommodation?

Planning permission is not normally required to convert a garage into additional living accommodation provided that:

  • The additional accommodation would be incidental to the main use of the dwelling  (i.e. home study or playroom) and a separate or independent unit of accommodation is not created;
  • The works are internal, and no extensions are required to carry out the works;
  • If a garage door needs to be replaced by a window the window is of a similar appearance and finish to those already used on the dwelling and is flush with the wall i.e. not a bay window.

Sometimes permitted development rights have been removed with regards to garage conversions and this is particularly likely to be true if you live on a modern housing development.  If you require further advice on whether planning permission is required for your proposed garage conversion, the Council offers a pre-application advice service.
