What does the Listing mean?
If a building is listed, then the WHOLE BUILDING is listed - both its exterior and interior.
A popular misconception is that only the outside is listed. Another is that only those features mentioned in the listing description are covered.
Fireplaces, staircases, plaster decoration and doors would all be considered to be listed regardless of whether the particular feature is referred to in the official description, which is there for identification purposes only.
The 'listing' included any structure or object fixed to the building or located within the boundary of the site of which the listed building forms part (ie: the curtilage). For example, if a farmhouse is listed, then any farm buildings and walls within the curtilage of the house would be considered listed as well, provided they were built before 1st July 1948.
