EXTENDING A LISTED BUILDING
If you want to build on a listed property, you’ll need to navigate the consents protecting its history. Alan Tierney delves into how to successfully add space to a heritage home
After a conversation with someone from English Heritage, Debbie and Laurence Osborne were encouraged that an ultramodern extension to their grade II listed home would be accepted, as long as the original structure was conserved. The result is a singlestorey cedar-clad addition with a zinc roof, which includes an exposed original wall in the new space

Extending a listed building will almost always be a much trickier proposition in comparison to adding space to an unlisted (and particularly modern) property. Getting it right and securing permission to do the project will involve a number of important and complex considerations. Here’s what you need to know.
Consent
Any extension to a designated property will require listed building consent (LBC). Whether you also need planning permission will depend on much the same considerations as any other extension. Listed buildings are often also in conservation areas, which usually means that permitted development rights have been restricted (always worth checking with your local planning authority). Note also that any demolition in a conservation area will need planning permission, for example if there is a preexisting extension to be removed as part of the work.
