If you want to develop a listed building and and it is considered that your proposals would affect the character of the building in any way, you’ll need listed building consent.
You may need consent for work on a listed building itself or for buildings or boundary walls within the curtilage of a listed building.
It is a criminal offence to undertake works to a listed building without getting Listed Building Consent in advance.
In general, you will need listed building consent for:
This is not a definitive list and if you own a listed building you should always check whether you need consent for any planned work.
You will also need listed building consent to build an extension, or any other work that would physically abut or attach itself to the listed building. You may also need planning permission.
Buildings are often added to the statutory list as a result of surveys or may be 'spot listed' individually as a result of a request. Anyone can ask for a building to be spot listed, but not all proposals are successful.
The general criteria for including a building in the statutory lists are as follows:
Buildings built before 1700 which survive in anything like their original condition are normally eligible, as are most buildings built between 1700 and 1840. For newer buildings, the selection requirements get progressively stricter.
When they consider whether to list a building, the Welsh Assembly is advised by Cadw’s Inspectorate of Historic Buildings, who look at the following criteria:
A proposal for listing should be supported by a location map, photographs (internal and external), a brief description of the building with building date (if known), owner details (if known) and any other historical or architectural information which makes the building special.
The inspectors will make an initial appraisal based on photographs and information supplied. If the building seems a good candidate a site inspection will follow which may be followed by a recommendation that the building be listed. All recommendations are then either confirmed or rejected by the Secretary of State.
Since most applications for spot listing are made because of a particular threat to the building it is important to make clear the nature of the threat and the timescale involved. If a building has been rejected for listing in the past few years, the case will only be reconsidered if new information is provided.
