Can I Extend My Home Without Planning Permission?
One of the first questions I'm asked is:
"Can I extend my home without Planning Permission?"
The honest answer is...
Maybe.
Many homeowners are surprised to learn that some extensions can be built under Permitted Development Rights, meaning you may not need full Planning Permission.
However, it's rarely as simple as a yes or no.
Here are just a few things that can affect whether your extension qualifies:
🏡 The size and height of the extension
📍 Whether your property is detached, semi-detached or terraced
🌳 If you live in a Conservation Area, National Park or Area of Outstanding Natural Beauty
🏠 Whether your home has already been extended in the past
📐 The distance from boundaries and neighbouring properties
I've spoken to homeowners who have spent weeks designing an extension, only to discover it doesn't meet the criteria—or worse, started building before checking altogether.
A quick conversation at the beginning of a project can save months of delays and potentially thousands of pounds in redesign costs.
Every home is different, which is why getting the right advice early makes all the difference.
Thinking about extending your home?
Drop your question in the comments or send me a message. If I can answer it, I will—and if I think there are things you should check before moving forward, I'll tell you those too.
After all, the best projects start with the right questions.
