Do I need planning permission in Bishopbriggs?
In Scotland the questions are whether the extension falls within householder permitted development (Classes 1A to 1D) or needs planning permission from the council, and the building warrant, which is required before construction begins and is followed by a completion certificate.
Homes in conservation areas, national scenic areas and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Applications are decided by your council as planning authority.
