How Close to a Fence Can You Build a Shed? (And What to Do If Your Neighbour Has Built Too Close)

A common question we get here at Taylors Garden Buildings — and we imagine a frequently asked Google shed question in the UK — is simple: how close to my fence can I actually build?

Whether you're planning a new shed, a log cabin, or a garden room, getting this right from the start saves you a lot of headache down the line. And if it's your neighbour's shed that's crept a little too close for comfort? We'll cover that too.

Is There a Legal Minimum Distance From a Fence?

There is no single law that states exactly how many centimetres you must leave between a shed and a boundary fence. However, the rules that do apply come from a combination of permitted development rights, building regulations, and common law principles — and they matter.

Here's what you need to know.

Permitted Development: The Key Rules

Most domestic garden sheds fall under permitted development, meaning you don't need formal planning permission — as long as you stay within certain limits. The relevant rules in England (Scotland, Wales and Northern Ireland have slight variations) include:

• The shed must not cover more than 50% of the curtilage (the total land area around your home, not including the house footprint itself).
• Maximum height: 2.5 metres if within 2 metres of a boundary. If the shed is further than 2 metres from the boundary, it can be up to 4 metres (dual-pitched roof) or 3 metres (any other roof style).
• The shed must not be forward of the principal elevation — in most cases, that means it can't sit in front of your house.
• It must not be used as a separate dwelling.

So while there's no absolute "you must leave X metres from the fence" rule, the 2-metre / 2.5-metre height rule is the one most people run into. In practice, most homeowners site their shed at least 300mm–600mm from the fence. This isn't just about rules — it's about maintenance access, airflow, and preventing damp.

Taylors tip: Always leave at least 300mm (30cm) between the back of your shed and a fence or wall. It makes treating the timber, clearing leaves, and checking for damp far easier — and it could save you money on maintenance long-term.

What About Building Regulations?

For most standard garden sheds, summerhouses, and log cabins under 15m² floor area, building regulations do not apply. Between 15m² and 30m², you're still generally exempt provided the building is at least 1 metre from any boundary or is constructed of substantially non-combustible materials.

Above 30m² (think large garden rooms and bigger log cabins), building regulations approval is likely required.

If you're putting in electrics, plumbing, or using the space as a habitable room, those elements will also need to meet building regulation standards regardless of the shed's size.

Does It Matter Which Boundary It's Near?

In terms of the planning rules, no — the 2-metre rule applies to any boundary, whether it's a shared fence with a neighbour, a wall, or even a public road. However, when it comes to neighbour relations, a rear boundary matters very differently to a shared side boundary.

Sheds placed close to a shared side or rear boundary are the ones most likely to cause issues:

• Light: Could it block natural light to a neighbour's windows or garden?
• Drainage: Could rainwater runoff from the roof land on their property?
• Privacy: Could someone stand at a window in the shed and overlook a neighbour's garden?
• Aesthetics: Is it an eyesore viewed from their side?

None of these are reasons to refuse planning permission on their own (there's no "right to a view" in English law), but they are the things that tend to start neighbourly disputes.

My Neighbour Has Built Their Shed Too Close to My Fence — What Can I Do?

This is a surprisingly common situation, and it can be frustrating — especially if you feel the shed is affecting your light, your privacy, or the condition of your fence. Here's a sensible step-by-step approach.

1. Don't Start With a Letter From a Solicitor

Boundary disputes are notoriously difficult and expensive to resolve through legal channels. Most of the time, a calm, friendly conversation resolves things faster and preserves the relationship. Start there.

2. Check Whether They Needed Planning Permission

If the shed is large, tall, or very close to the boundary, it's worth checking whether they should have applied for planning permission. You can check what was and wasn't permitted by searching your local council's planning portal — most councils have these online.

If a structure was built without required planning permission, you can make a planning enforcement complaint to your local council. The council isn't obliged to act, but if there is a genuine breach, they can require the owner to apply retrospectively or remove the structure.

3. Consider the 4-Year Rule

Planning enforcement has time limits. In England, local authorities generally cannot take enforcement action against a building that has been in place for 4 years or more without challenge (this is changing — the Levelling Up and Regeneration Act 2023 is extending this to 10 years for most breaches, though the transition is phased). So if the shed has been there a while, enforcement may no longer be an option.

4. Think About Boundary Ownership

If your neighbour's shed is actually on your land — even partly — that's a different matter. Deeds and title documents (available from HM Land Registry) confirm where the boundary sits. If the structure encroaches onto your land, you have the right to ask for it to be removed. This is where a solicitor may be worth consulting.

5. Consider Mediation

Before any legal route, consider a community mediation service. These are often free or low-cost, and a neutral third party can help reach an agreement without the stress and cost of going to court.

6. The Party Wall Act — Is It Relevant?

The Party Wall etc. Act 1996 applies to work on or near a shared boundary wall, or work that could affect a neighbour's structure. A free-standing garden shed generally won't trigger it, but if your neighbour has built up against a shared wall or their foundations come within 3–6 metres of yours, it could be relevant. A party wall surveyor can advise.

What If I Want to Build Close to the Boundary — Can I Just Ask My Neighbour?

Absolutely — and it often goes better than people expect. If your ideal shed position would take you close to a shared boundary, a friendly conversation with your neighbour before you start is always a good idea. You might also consider:

• Positioning the shed so any roof overhang doesn't drip onto their side. This is a common courtesy and avoids damp issues on both sides.
• Treating the side of the shed that faces them. A well-maintained, painted or pressure-treated finish looks far better from their garden than bare, weathered timber.
• Choosing a sympathetic style. A timber shed with a green or brown roof blends into a garden far more than an industrial-looking metal structure.
