No. Many extensions will be what’s considered a ‘permitted development’, for which there is no need to apply for planning permission. Whether an extension will come under the cusp of permitted development, or if it will need planning permission, is subject to numerous regulations affecting the size and positioning of the extension, as well as the materials used in its construction.
Although deciding if a project will need planning permission can sometimes be complex, you don’t need to worry about any of this. As part of the Europa’s extension service, we can assess if your extension would require planning permission and can even take care of any applications for you!
It’s worth noting that, even if your particular project doesn’t need planning permission, it can still be a good idea to obtain a ‘Lawful Development Certificate’ to prove to potential buyers or their legal representatives down the line that the building works completed are lawful.
