Thinking about adding a new shed to your garden? Before you do, you’ve probably asked the question: “Do I need planning permission for a shed?”
In most cases, the answer is no, but there are exceptions. This guide breaks down exactly when you do need permission, including shed size limits, placement rules, and how the purpose of your shed can change things.
1. When a Shed Doesn’t Need Planning Permission
Most garden sheds in England are classed as “permitted development.”
That means you can build one without applying for planning permission, if you follow the rules below.
Your shed is likely permitted if:
- It’s used for domestic purposes only (e.g. storage or workspace).
- It doesn’t take up more than 50% of your garden area.
- It’s under 2.5m high if placed within 2m of a boundary.
- It’s under 4m high with a dual-pitched roof (or 3m for other roofs).
- It’s not in the front garden.
👉 Rule of thumb: Keep your shed under 2.5m tall and away from boundaries, and you’ll likely avoid planning altogether.
If you’re unsure, the team at MCD Garden Buildings can help you pick a model that fits within UK guidelines — and handle the installation, too.
2. When You Do Need Planning Permission
There are times when a shed crosses into “planning required” territory. You’ll need permission if:
- The shed sits in front of your house or faces a public road.
- Your home is listed or in a conservation area.
- The shed is used as accommodation or living space.
- It’s over 4m high or takes up more than half the garden.
So yes, you can build most garden sheds without permission, but once you move into habitable or oversized territory, planning rules apply.
3. Shed Location: What You Need to Know
- Back garden: ✅ Usually fine — this is where most sheds go.
- Side garden: ⚠️ Often fine, but check boundary distances.
- Front garden: 🚫 Usually needs planning — sheds here affect street views.
If your shed can be seen from the road, always confirm with your Local Planning Authority (LPA) before buying.
4. How the Shed’s Use Affects Permissions
Your shed’s purpose can change whether it’s allowed under permitted development:
| Use | Planning Needed? | Notes |
|---|---|---|
| General storage | ❌ No | Standard use — usually fine |
| Home office / gym | ⚠️ Sometimes | May need Building Regs for electrics |
| Living space / accommodation | ✅ Yes | Always needs planning + building control |
Even if you’re converting it into a home office, keep it simple and compliant. Once you add insulation, plumbing, or sleeping space, it’s a different category.
5. Applying for Planning Permission (If Needed)
If your shed doesn’t meet the rules above:
- Contact your local planning office for advice.
- Submit plans showing shed size, design, and location.
- Wait up to 8 weeks for approval.
It’s straightforward but slow, so plan early if your design pushes the limits.
6. Quick Summary
Most UK sheds don’t need planning permission.
But if yours is tall, large, in a conservation area, or used for living space — you’ll need approval first.
Key points to remember:
✅ Under 2.5m high = safe near boundaries.
✅ Don’t take up more than half the garden.
✅ Avoid front gardens without planning.
✅ Living or overnight use = always needs approval.
