🏡 Planning Permission Rules for House Extensions in Bishop’s Stortford – What You Need to Know 🧱
Thinking about adding extra space with a home extension in Bishop’s Stortford? Whether you’re planning a rear kitchen extension, utility room, or side return, it’s important to understand when you need planning permission — and when you don’t.
⸻
✅ You Might Not Need Planning Permission
Many house extensions fall under Permitted Development (PD) rights, which means you can extend your home without a full planning application if the extension meets certain limits:
✔️ Detached houses – can extend up to 4 metres from the rear wall
✔️ Semis or terraced houses – up to 3 metres
✔️ Maximum height – 4 metres for a single-storey extension
✔️ Materials must be similar to your existing home
✔️ The extension must not cover more than 50% of your garden
📌 PD rights may not apply if your property has already been extended significantly or has restrictions.

🏘️ When You Do Need Planning Permission in Bishop’s Stortford:
🚫 If your extension exceeds the PD size or height limits
🚫 If your home is in a conservation area — such as parts of Newtown, South Road, or Bishop’s Stortford town centre
🚫 If your property is listed
🚫 If you’re planning a two-storey extension, or extending near a boundary
🚫 If the materials or design don’t match the existing building
