How does a structure get listed?
A building, structure or object can be added to the list for the following reasons:
- Architectural Interest
- Historical Interest
- Close Historical Associations and/or Group Value - these are not considered on individual merit of the structure, but form part of a group of buildings of architectural or historical value
It's important to remember that a Listed Building includes any object or structure which is fixed to it or within its curtilage, which although not fixed to the main building forms part of the land and has done so since before 1 July 1948. This means, for example, that structures associated with a Listed Building like barns or pigsties built before 1948 would also be treated as listed buildings.
