In the UK, most sheds do not require planning permission as long as they fall within permitted development rules. The two things that matter most are how tall the shed is and how close it sits to a boundary.
I’ve built and installed numerous sheds, garden rooms and outbuildings over the years, and these are the exact rules I work to on every project.
Maximum Shed Height UK
The maximum height of a shed in the UK depends on how close it is to your boundary.
| Shed location | Maximum overall height |
|---|---|
| Within 2 metres of any boundary | 2.5 metres |
| More than 2m from boundary – dual-pitched roof | 4 metres |
| More than 2m from boundary – any other roof type | 3 metres |
The 2.5 metre limit is the one most people encounter, because in a typical UK garden, sheds are usually positioned close to a fence or boundary wall. If your shed is within 2 metres of a boundary, the 2.5 metre maximum applies regardless of roof type. Even a dual-pitched roof cannot exceed this.
Shed Distance from Boundary in the UK
There is no minimum distance you must leave between your shed and a boundary. You can build right up to the boundary line, as long as no part of the structure overhangs a neighbouring property.
What planning rules actually control is the height based on that distance, not the distance itself.
In practice, I always recommend leaving a small gap for maintenance and access, especially if you need to treat the timber or access the back of the building. But it is not a planning requirement.
Building within 1 metre of a boundary
Building within 1 metre of a boundary is perfectly legal under permitted development, as long as the overall height does not exceed 2.5 metres. The 2-metre boundary rule sets the height limit. There is no separate rule that specifically restricts the 1-metre mark for planning purposes.
However, Building Regulations, which are separate from planning permission, do apply here. If your shed is over 15m² and sits within 1 metre of a boundary, it must be built from substantially non-combustible materials. Buildings over 30m² require Building Regulations approval regardless of boundary distance.
Full List of Permitted Development Conditions for Sheds
For a shed to qualify as permitted development (no planning permission required), it must meet all of the following:
1. Not forward of the principal elevation. The shed cannot be built in front of the main wall of your house that faces the road. If your house has two walls forming the principal elevation, the shed cannot be built in front of either.
2. Single storey with the correct height limits. Sheds must be single-storey. Maximum eaves height is 2.5 metres. Maximum overall height is 4 metres for a dual-pitched roof, or 3 metres for any other roof type, unless the shed is within 2 metres of a boundary, where 2.5 metres overall applies regardless.
3. No verandas, balconies or raised platforms above 30cm. Any platform, decking, or raised area must not exceed 0.3 metres in height. On sloped ground, this is measured from the highest ground level adjacent to the structure.
4. Covers less than half the original garden area. The total footprint of all outbuildings and extensions combined cannot exceed 50% of the land surrounding the original house. The “original house” means the house as first built, or as it stood on 1 July 1948.
5. Special rules for designated land. If you live in a National Park, Area of Outstanding Natural Beauty, the Broads or a World Heritage Site, outbuildings more than 20 metres from the house are limited to 10m² in footprint. Side-of-house outbuildings on designated land require planning permission.
6. Listed buildings require consent. If your property is a listed building, any outbuilding requires planning permission regardless of size or location.
What Is the Curtilage of a Dwellinghouse?
The term “curtilage of the dwelling house” appears in the planning rules and simply means the land that belongs to and surrounds your home, your garden, driveway, and any outbuildings within the boundary. It is the private space connected to the dwelling that sits within your property boundary.
How to Apply for Planning Permission
If your shed falls outside permitted development rules, you’ll need to apply for planning permission. Here’s how:
- Check whether you need it, use the guidance above, or contact your local planning authority (LPA)
- Familiarise yourself with your local planning policies
- Submit an application via the Planning Portal. You’ll need drawings, plans and a fee
- Your LPA may consult neighbours and relevant bodies
- A decision is usually issued within 8–13 weeks
If you’re unsure, it’s worth speaking to your LPA before you build. They can confirm whether your project needs permission or give informal guidance.
Common Questions
Do I need planning permission for a shed in the UK? In most cases, no. If your shed meets the permitted development conditions above, correct height, correct location, under 50% garden coverage, you can build without applying for planning permission.
Can I build a shed next to my neighbour’s fence? Yes. There is no minimum gap required by planning rules. You just need to ensure no part of the structure overhangs the boundary. Practically speaking, leaving 50cm or so gives you room to maintain the exterior and carry out any fence repairs.
What is the maximum size shed without planning permission? There is no specific maximum footprint for permitted development, as long as the shed covers less than 50% of the garden area and meets all height and location conditions. Building Regulations are a separate matter. Buildings under 15m² are generally exempt. Those between 15m² and 30m² may need to be 1 metre from a boundary or use non-combustible materials, and buildings over 30m² normally require Building Regulations approval.
Can I sleep in my shed? Not without additional consents. Using a shed as sleeping or living accommodation can trigger planning permission requirements, Building Regulations, and fire safety obligations. For occasional overnight use or more permanent conversion, check with your local authority before you build.
What is the maximum size of a summerhouse without planning permission? The same rules that apply to sheds apply to summerhouses. They are both classified as outbuildings. The 2.5m height limit applies within 2 metres of a boundary, coverage must stay below 50% of the garden, and the structure cannot sit forward of the principal elevation.
Does the 1 metre boundary rule apply in Scotland? Scotland has its own permitted development regulations, which differ slightly in wording from England. The general principle of height limits near boundaries is similar, but you should confirm the current rules with your local planning authority or check the Scottish Government’s householder permitted development guidance.

Resources and Common Sense
Here are some extracts from the official documentation on the matter of ground-level measurements. These state that the height should be measured from the area closest to the ground. The section on the right in the above image.
You can read the full guide here: https://www.gov.uk/government/publications/permitted-development-rights-for-householders-technical-guidance
“Height” – references to height (for example, the heights of the eaves on a house
extension) is the height measured from ground level. (Note, ground level is the surface of
the ground immediately adjacent to the building in question, and would not include any
addition laid on top of the ground such as decking. Where ground level is not uniform (for
example if the ground is sloping), then the ground level is the highest part of the surface of
the ground next to the building.)
And building is defined as:
“Building” – includes any part of a building and includes any structure or erection, but does
not include mechanical plant or machinery or gates, fences, walls, or other means of
enclosure.
From this document, it should be understood that the measurement is taken from the point closest to the ground. As described above, always talk to neighbours and use common sense that your shed platform is not going to impact anyone around you.

We can apply a lot of common sense when planning the best location and size for our sheds. These restrictions and rules are put in place to protect each other from placing structures that might impose on each other. After all, you wouldn’t want someone to build a shed that blocks out most of your natural sunlight or prevents you from seeing natural scenery from your house.

With consideration and communication, we can all find a solution that works and doesn’t infringe on anyone. Stick within these rules and there shouldn’t be any cause for concern. If in doubt, talk to your neighbours and failing that check with your local planning authority for the green light on your perfect shed design and location.
