You can check online through the UK Government Planning Portal to see if your extension plans are likely to need planning permission. Even if your extension is considered a Permitted Development. We recommend that you obtain a Lawful Development Certificate. A Lawful Development Certificate is basically a letter from you Local Authority that confirms you can build without Extension Planning Permission and you can be sure that you're not breaking any rules. This certificate will also be important if you eventually come to sell your house. A Lawful Development Certificate Application would require architectural extension drawings
