Listed buildings are something of a speciality of ours. We have over 25 years of experience working on old buildings, and we know it’s a process that takes skill with documentation and administration, as well as construction and building expertise. Luckily, we’ve got lots of know-how with both! The answer to ‘Can I Build An Extension On My Listed Building’ is… maybe!
While you always need express permissions from the Local Planning Authority to undertake any construction or renovation projects on a Listed Building, you’d be surprised about the flexibility that you can have within the LPA’s stipulations and permissions. If you want to know how to find your Local Planning Authority contact address, type your postcode into this LPA website. (For much of Cornwall, this will be Cornwall Council; find its Planning Portal here.)
You will also need to apply for Listed Building Consent if you want to build an external structure, such as a conservatory or extension of external walls etc. This is an application form you can also get from Cornwall Council; find out more about the application for Listed Building Consent in Cornwall here.
There is some guidance on this from National Heritage; if the renovations or extensions are deemed ‘useful’ and ‘viable’, extensions and renovations can be considered. When you make your proposal for the extension you want to make, you must show that you understand what these changes will do to your building, and to the area around it. For example, if you are adding a glass conservatory to a granite cottage, do you understand what this will do to the stonework, and to the temperature of those exterior walls, and how will its use as a conservatory affect the masonry and any pointing etc? At this stage of writing your proposal, it’s a good idea to get a constructionist or builder to look over and give you some advice on the planning permission proposal, as an experienced builder will understand the true effect of the building work or extension.
Any Local Planning Authority will require the following documentation, which should all be submitted in one go, at one time:
As you plan your extension on your Listed Building with your builder or construction team, you should ask them about the ‘permanence’ of any changes or modifications to your Listed Building. For example, if you’re adding an extension, could the extension be removed, if it really came down to it. A Local Planning Authority is more likely to say yes, if they feel that any risks can be reversed and mitigated for.
