Currently, around one in three of all CWAC planning applications are for house extensions. It’s hoped that the new supplementary planning document — approved at today’s (January 13) council cabinet meeting — will make it easier for applicants to understand what is permitted in their area. Cllr Matt Bryan, cabinet member for housing, said: “One-third of our planning application is about house extensions. Many of the applications are submitted without professional support. “Our officers have wanted to get this in place for a while and we have been [collating] three support documents from legacy authorities into one document, which sets out to residents how house extensions can be done.
