Are you are searching for some inspiration and design ideas for a listed building extension?
Whether you want to alter or extend a Grade II listed barn or 17th-century cottage, that will affect its character or appearance, you will need to make sure you comply with the requirements and gain listed building consent from your local planning authority.
Buildings are appointed a listed status to mark their historical and architectural interest,
A listed home is a historic building protected by the Secretary of State (Digital, Culture, Media and Sport) and is placed on the statutory National Heritage List for England.
A listed status also preserves the building from any inappropriate alterations or extensions.
There are three different listed buildings categories in the UK:
Grade I buildings are of exceptional national or even international, architectural or historic interest. Examples of these are Buckingham Palace, Tower Bridge and Portchester Castle
Grade II* buildings are of particular national importance and of more than special interest. Examples of these are Battersea Power Station and Cleveland Bridge.
Grade II buildings are of particular architectural interest. Examples of these are the BT Tower and Surbiton railway station.

To proceed with a listed building extension, you will need to gain Planning Permission, Building Regulations approval and Listed Building Consent.
This process can be a long procedure and you will need to submit your architecture design plans, and proposals to your local authority, and usually takes up to 6 weeks.
The rules and regulations around what you can and can’t do vary for a listed building extension so be sure to do your research; know and understand the history of your property and the local area. It is also recommended to contact your local authority conservation officer before submitting your planning application to seek advice on what can gain approval.
You will need to understand the features that contribute to the character of your property and demonstrate that you have considered these in your plans.
Following the advice of either your conservation officer, architect, structural engineer, builder and glazing specialist can help to ensure your plans get approved.
Structurally glazed extensions are translucent by nature, they don’t obscure the original building like other options might. It is more likely to get approval for a glass extension on a listed building because the design will maintain the original architectural quality of your property.
Glass extensions have the unique ability to be unobtrusive, whilst at the same time standing out as a beautiful, modern addition to property.
There are many styles of glass extensions, and an architectural glazing specialist will be able to advise of the best type of extension for your property.
