Understanding Planning Permission

If you’re planning to renovate and extend your property, you may be wondering if you need planning permission and whether you’ll be given the thumbs up to start your project. The thought can be daunting – especially if you need more space for a growing family or have your heart set on a remodel – but the good news is planning permission for your home isn’t always needed.

In fact, many home development tasks can be done under Permitted Development Rights, saving you a lot of time and worry.

What can I do Without Applying for Planning Permission?

Internal remodelling

If you’re not extending beyond the initial footprint of the dwelling, internal remodelling is generally allowed – although you’ll probably have to comply with specific building regulations. This means that, as a rule, you can be as creative as possible to maximise the space within you home – unless, of course, you live in a listed property and then any changes may be prohibited.

Loft Conversions

Whether you’re looking to create a new bedroom or give the kids somewhere to hang out, a loft conversion could be the way forward. This doesn’t usually require planning permission; however, if dormer windows are installed to create additional headroom, they must not sit higher than the highest part of your existing roof – or extend forward of the roof plane on the principal elevation.

Therefore, if you wish to create something big, bold and better than just a traditional loft renovation, you’ll most likely have to go through the process of securing planning permission first. If you don’t, it is perfectly plausible that you’ll be asked to undo all changes, so never take the risk of starting a project before you get the green light.


Believe it or not, you can even add many extensions without going through the hassle of planning applications, so it’s worth doing your homework to find out more about what is and isn’t allowed as this could help with your redesign. If you do decide to build a grand new bedroom or to add a new wing to your home with an additional bathroom, however, there are many rules and regulations to follow. One of these is that the extension must not be more than half the area of land around the original house. What’s more, your extension should not be forward of the principal elevation or side elevation onto a highway or be higher than the highest part of the roof.

There really are a vast array of don’ts and can’ts concerning extensions, but as a rule if you’re planning a small project you should be fine – it’s the larger ones which tend to require full planning permission. Modest conservatories are usually considered to be okay, as are sheds and outbuildings, so long as they do not sit forward of the original elevation, are of the correct height depending on the type of roof, are single storey, and do not exceed 50 per cent of the total curtilage.

As for two-storey extensions, these can be built without planning permission if they’re at the rear of the property, do not exceed three metres in depth, and are within seven metres of the rear boundary.
