Do You Need Planning Permission for Your Extension?

Do You Need Planning Permission for Your Extension?

One of the most common questions we hear from homeowners is "Do I need planning permission?" The good news is that many home extensions and improvements fall under what is known as Permitted Development rights, meaning you may not need to apply for planning permission at all.

What is Permitted Development?

Permitted Development (PD) rights are a set of rules that allow certain types of building work to be carried out without the need for a formal planning application.

Extensions Under Permitted Development

For a typical detached house, you can generally extend under PD if the extension does not exceed 50% of the area of the original house.
