Planning Permission for House Extensions (Made Simple)
Thinking about extending your home but not sure where to start?
Whether you're planning a bigger kitchen, extra bedroom, or open-plan living space, the first question is always the same:
Do I need planning permission?
This question can impact how quick you can start on site, what you need to spend upfront before a spade is in the ground, how big you can go and, ultimately, whether your planned project can get off the ground or not.
At Fellpath Planning, we help householders across England get clear, practical answers—fast.
What You Can Do Without Planning Permission
Many home extensions fall under permitted development rights—meaning you might not need full planning permission at all.
But the rules are impacted by:
How far you want to extend
Your house type (semi, terrace, detached)
Previous extensions
Conservation areas or National Parks
Get it wrong, and you risk:
Council Enforcement action
delays
wasted build cost
problems selling your home in the future
