QUICK GUIDE WHAT IS LISTING?

What is a listed property?

A building is listed when it is of special architectural or historic interest in a national context. Most properties built before 1850, still in their original condition, are listed – whether simple terraces or stately homes.

There are three categories. Those with grade I status are properties of exceptional interest, and only 2.5% of all listed buildings fall into this category. Grade II* are particularly important buildings of more than special interest; they make up 5.5%. Grade II are of special interest and comprise of 92% of all listed buildings.

Do I need special permission to extend?

Listed building consent is needed for any work that involves altering, extending or demolishing a listed property. An expert historic buildings architect, surveyor or consultant can help you establish whether listed building consent is needed. These matters are also covered in Historic England Advice Note 16: Listed Building Consent. Doing unauthorised building work to a listed building is a criminal offence and the local planning authority (LPA) could insist work is reversed.

What restrictions might I face?

It’s difficult to give general advice on this – in one house, the back elevation of the building might have little significance and thus be suitable for extending. But in another, the rear facade might be its most important feature. To explore your options and improve your chances of obtaining consent, talk to your expert consultant before developing any plans, and then to the conservation advisor at the LPA.
