What does listing mean? What special features of my building are listed?

Once a building is listed then the whole building is protected: interior, exterior, including any later additions to the historic structure and ‘modern’ extensions.

The list description is not intended to be a catalogue of all features of interest. Some older descriptions are very brief and do not mention interiors, whilst the most recent are more detailed.
Any structure within the curtilage of the listed building such as outbuildings and walls constructed before July 1948 are also protected by the listing of the primary structure, but some structures may be individually listed.

The ‘curtilage‘ is commonly the area around a building within the property boundary, but this may be open to interpretation. If you are in doubt about the status of a structure then consult the Historic Buildings Officers.
