Front extensions change the street scene, which is why they face higher scrutiny than rear or side extensions. They are never permitted development and always require a planning application.
What these results show
• Front extensions have one of the highest refusal rates of any extension type.
• Street scene impact is the number one refusal reason — councils protect visual consistency.
• Porches are treated differently to front extensions and often have permitted development rights.
• Where a neighbour has an approved front extension, your chances improve significantly — precedent matters here more than anywhere.
⚠️ These are national examples. Your council could be stricter — or more lenient. See what actually gets approved on your street →
