. . . Listed Buildings In Wales Continued
Grading
All properties considered for listing are judged according to
a set of standards and graded to reflect their relative architectural and historic
interest.
Grade I - buildings of exceptional interest
Grade
II* - particularly important buildings of more than special interest
Grade II - of special interest, warranting every effort to preserve them.
Buildings built before 1700 which survive in anything like their original
condition are listed, as are most of those built between 1700 and 1840. Post-1945
buildings have to be exceptionally important to be listed. Normally a building
has to be over 30 years old to be eligible for listing. Buildings less than 30
years old would normally only be listed if they were of outstanding quality and
under threat. Buildings less than 10 years old are not listed.
Restrictions
If you wish to demolish a listed building or to alter or extend
it in a way that affects its character as a building of special architectural
or historic interest, you must apply for listed building consent from your local
planning authority.It is an offence to demolish, alter or extend a listed building
without listed building consent.
Before starting any work - even painting
- you should consult your local planning authority. Listed building consent is
in addition to any planning permission needed. For most owners, however, applications
for both can be considered. Listed buildings consent applications are free.
Planning permission alone is not sufficient to authorise demolition.
Certain of the developments relating to dwelling houses permitted by the
Town and Country Planning General Development Order do not apply to listed buildings.
Advice on such matters can be obtained from your local planning authority.
If you are granted listed building consent to demolish a building, either
in part or wholly, the Royal Commission on Historical Monuments must be informed
to make a record of it
