Wondering if you can avoid making a full planning application? Our planning expert advises on the ins and outs of Permitted Development

Asa planning consultant, one of the first questions I’m often asked is, “Do I need planning permission for my extension?” The answer depends on several factors, and it’s not always straightforward.

Some extensions fall under Permitted Development (PD) rights, meaning you don’t need to apply for planning permission. But there are strict rules about what qualifies. If your proposed extension doesn’t meet these criteria – or if your property is in a sensitive area – you’ll need to go through the planning application process.

The type, size and location of your extension all play a role. For instance, larger two-storey rear extensions or extensions that go beyond the front of your house almost always need planning permission. The same applies if your property is listed or in a conservation area, as these are subject to additional restrictions.

The details of any previous planning consents for your property are important, too. If those consents included a condition that removed PD rights, then you can’t use them for your specific house.

In this article, I’ll guide you through the key points so you can work out whether your extension needs planning permission —or whether you’re lucky enough to fall under Permitted Development. Let’s start with what you can do without seeking permission.

WHAT YOU CAN BUILD WITHOUT PERMISSION

The good news is that PD rights may allow you to make certain changes to your property without the hassle of applying for permission —provided you stick to the rules. These are outlined in detail on the government website planningportal.co.uk.
