We are proud to have many fine buildings and areas which are distinguished by their architecture, history and landscape in our districts. Listing ensures that the architectural and historic interest of the building is carefully considered before any alterations, either outside or inside, are agreed.
The older a building is, the more likely it is to be listed. Buildings built before 1700 which still exist in anything like their original condition are listed, as are most built between 1700 and 1840.
Since then, the criteria for listing has become tighter with time, with buildings built after 1945 needing to be exceptionally important to be listed. There are three categories of significance for listed buildings:
Grade I for buildings of the highest significance
Grade II* for buildings of particular national importance and special interest
Grade II for buildings of special architectural or historic interest
Most listed building owners are likely to be Grade II buildings as these make up approximately 94% of all listed buildings.
There is extra control over what changes can be made to a listed building's interior and exterior.
