How and why does a building get listed?
Buildings in the UK are listed for their special architectural or historic interest, which may include design, decoration, craftsmanship, and associations with significant people or events. The criteria for listing include age and rarity, aesthetic merit, selectivity, and national interest.
Buildings constructed before 1700 that retain original features are likely to be listed, whereas those built after 1945 must be of definite architectural quality and under threat to be considered.
Listed buildings are categorised into grades by significance, with Grade I the highest and Grade II the lowest. In England and Wales, Grade II* buildings are particularly important, while Grade II buildings are of special interest.
In the UK, listed building consent is required for any demolition, alteration, or extension of a listed building, and it is a criminal offence to carry out such work without first securing consent from the local planning authority. Listing protection applies to the entire building, including the interior, fixtures, fittings, and objects within the curtilage, even if they are not fixed.
De-listing is possible but rare, and emergency measures can be taken to protect buildings at risk of demolition or alteration that might affect their historic character.
