Planning Permission Garden Shed: Do You Need Permission in the UK?

Do you need planning permission for a garden shed?

In England, many sheds are treated as outbuildings. Outbuildings can often be built under permitted development rights, which means you do not have to submit a normal householder planning application as long as every relevant condition is satisfied.

However, permitted development is not simply a rule saying “small sheds do not need permission”. Your shed's location, height, roof design, proximity to the boundary and total amount of garden already developed all matter.

If you are unfamiliar with how permitted development fits into the wider planning system, our complete homeowner guide to the planning system is a useful starting point.

Planning permission garden shed size and height rules in England

One of the most common searches is for the maximum size garden shed without planning permission. There is no single permitted-development floor-area limit for an ordinary shed in England. Instead, several restrictions work together.

Maximum garden shed height without planning permission

For a detached outbuilding that otherwise qualifies as permitted development, the normal England limits are:

• Maximum eaves height: 2.5 metres.
• Maximum overall height with a dual-pitched roof: 4 metres.
• Maximum overall height with another roof type: 3 metres.
• If any part is within 2 metres of the garden boundary: the whole structure must normally be no more than 2.5 metres high.

How much of the garden can a shed cover?

The total area covered by extensions and other buildings within the curtilage must not exceed 50% of the land around the original house. The original house means the house as first built or, for an older property, as it stood on 1 July 1948.

Therefore, previous extensions, garages and other outbuildings can reduce the space available for another structure under permitted development.

You can read more about these wider restrictions in our guide to what homeowners can build without making a full application.

How close can a garden shed be to the boundary?

A shed can often be positioned close to a boundary, but this changes the permitted height. In England, if any part of an outbuilding is within 2 metres of the boundary of the property's curtilage, its maximum overall height under Class E permitted development is normally 2.5 metres.

This is why many standard garden sheds are deliberately designed to stay below 2.5 metres. Even so, planning permission and private boundary matters are separate issues. You should make sure the structure, roof overhang, guttering and foundations stay within land you own.

Do you need planning permission for a front garden shed?

A normal shed placed on land forward of a wall forming the principal elevation of the original house will not qualify under the usual Class E permitted development rules in England.

In practical terms, this means a conventional shed in the front garden will often require planning permission. The exact principal elevation is not always as obvious as simply identifying the door you use as your front door, particularly on corner plots or unusually designed houses.

If you are unsure whether your proposal falls within permitted development at all, see our homeowner permission-checking guide.

When does a large garden shed need planning permission?

A large garden shed does not automatically need permission simply because its floor area exceeds a particular number of square metres. For planning purposes in England, the more important questions are whether it stays within the Class E height, location, coverage and use restrictions.

Planning permission is more likely to be required where:

• the shed would be forward of the principal elevation;
• its height exceeds the permitted development limits;
• existing and proposed buildings would cover more than half the relevant land around the original house;
• the building is intended as separate residential accommodation;
• permitted development rights have been removed by a planning condition or Article 4 Direction;
• the property is a flat or maisonette rather than a qualifying house; or
• special restrictions apply because of designated land or a listed building.

Conservation areas, listed buildings and local restrictions

Special areas need more care. On designated land in England, additional restrictions apply to the position and scale of outbuildings. Structures within the curtilage of a listed building also fall outside the normal Class E planning permission allowance.

If your home is affected, our guides to planning controls in protected neighbourhoods and works affecting historic properties explain why an ordinary-looking garden project can require extra checks.

Does the way you use a garden shed affect planning permission?

Yes. Class E covers buildings used for purposes incidental to the enjoyment of the house. Ordinary storage, hobbies and similar domestic uses can fall within that description.

However, permitted development for an outbuilding does not allow you to create a separate self-contained dwelling or use the shed as primary residential accommodation. Adding sleeping, kitchen or bathroom facilities can therefore move the project into a very different planning and Building Regulations position.

A shed used occasionally for home working may also be different from premises operating as an independent business with staff, customers, deliveries or other impacts. If the proposed use changes the character of the property, separate planning considerations can arise.

Garden shed planning permission vs Building Regulations

Planning permission and Building Regulations are separate systems. A shed may not need planning permission but could still need Building Regulations approval depending on its size, construction and use.

In England, a small detached building of less than 15 square metres floor area will not normally require Building Regulations approval if it contains no sleeping accommodation. Between 15 and 30 square metres, an exemption can still apply where there is no sleeping accommodation and the building is either at least 1 metre from the boundary or constructed substantially from non-combustible materials.

Electrical work, drainage and a change to more intensive accommodation can introduce additional requirements. Our guide to compliance for detached garden structures explains this side of the project in more detail.

You may also find our comparison of the planning and Building Control systems useful if you are not sure which approval you are dealing with.

Are garden shed planning rules the same across the UK?

No. Planning is devolved, so England, Wales, Scotland and Northern Ireland have their own permitted development frameworks.

England

The rules explained above are based on England's Class E householder permitted development provisions.

Wales

Wales also allows many domestic outbuildings through permitted development, but its detailed siting and height rules should be checked against Welsh Government guidance rather than assuming the England rules apply.

Scotland

Scotland uses its own householder permitted development classes. For example, its rules for ancillary buildings have different boundary and eaves provisions, so a shed that complies in England should not automatically be assumed to comply in Scotland.

Northern Ireland

Northern Ireland also operates its own planning framework. Homeowners should check with the relevant council planning office where there is any doubt about permitted development.

Before you build your garden shed

For most straightforward garden sheds in England, planning permission is often avoidable because permitted development rights provide a practical route for ordinary domestic outbuildings. The important point is that all the relevant limits must be satisfied.

Position is often just as important as size. A modest shed in the front garden, a tall structure beside a boundary or a building on a property with restricted permitted development rights can all require a closer look.

Therefore, check the dimensions, boundary distance, existing garden coverage and intended use before ordering materials or starting foundations. When something is unclear, confirming the position with the local planning authority — or obtaining professional advice — is usually much easier than trying to resolve a planning problem after the shed has been built.
