Do You Need Building Regulations Approval for Your Extension?
Are you planning to add an extension to your property? For most home additions, you'll typically need to get approval under the Building Regulations. These important rules guarantee your new space will be built safely, be easy to access, and function efficiently when it comes to energy.
However, it's good to know that certain specific types of new buildings or extensions are actually exempt from needing this approval.
The upcoming sections will guide you through the key considerations you'll generally need to keep in mind to ensure your extension meets the Building Regulations' requirements.
