In the
United Kingdom the term 'listed building' refers to a building or other structure officially designated as being of special architectural, historical or cultural significance. It is a widely used status, applied to around half a million buildings.A listed building may not be demolished, extended or altered without special permission from the local planning authority (who typically consult the relevant central government agency, particularly for significant alterations to the more notable listed buildings). Owners of listed buildings are, in some circumstances, compelled to repair and maintain them and can face criminal prosecution if they fail to do so or if they perform unauthorised alterations. Because of this, and because listing can limit the options available for significant expansion or improvement, the law allows for owners of listed buildings to object to the listing.
