Most garden sheds do not need planning permission in England, as they fall under Class E permitted development (outbuildings) — provided they are not forward of the principal elevation, do not exceed 2.5m height within 2m of a boundary, and total outbuilding coverage stays under 50% of the garden. Building regulations are generally not required for sheds under 15m². This guide covers the exact height and size limits, placement rules, and what happens if you use a shed for something more than storage.

Key Shed & Outbuilding Planning Facts (England, 2024)
- Class E covers all outbuildings: sheds, summer houses, workshops, greenhouses
- 2.5m max height within 2m of boundary; 4m dual-pitched, 3m other roofs
- 50% max garden coverage | Not forward of principal elevation
- No sleeping accommodation permitted under PD
- Building regs: exempt under 15m²; conditionally exempt 15-30m²
- Must be "incidental to the enjoyment of the dwelling house"
Sheds fall under Schedule 2, Part 1, Class E of the GPDO — the rules for "buildings incidental to the enjoyment of a dwellinghouse." You can build a shed without planning permission if:
Height Limits
- Dual-pitched roof (apex): Maximum 4 metres high
- Any other roof type (flat, mono-pitch, pent): Maximum 3 metres high
- If within 2 metres of a boundary: Maximum 2.5 metres high regardless of roof type
The 2.5-metre boundary rule is the one that catches most people. If your shed is anywhere near a fence line, the maximum overall height is 2.5 metres — that's about 8 feet 2 inches.
Size and Coverage
- The shed, together with all other outbuildings and extensions, must not cover more than 50% of the garden (the land around the original house)
- No minimum size — a 6x4 garden shed is fine, so is a 6x3 metre workshop, provided it meets other rules
Placement
- Must not be built forward of the principal elevation (the front of the house)
- Must not be on land between the side elevation and the boundary where that side faces a highway
- Must be within the curtilage (garden/grounds) of the house
Use
- The building must be incidental to the enjoyment of the dwellinghouse — storage, workshop, home office, gym, hobby room
- It must NOT be used as separate living accommodation — no sleeping, no independent dwelling
- If you turn a shed into a self-contained living space, it becomes a change of use requiring planning permission
Listed Buildings
If your property is listed, you need listed building consent for any outbuilding within its curtilage. A shed in the garden of a Grade II listed house needs consent even if it would otherwise be permitted development.
Conservation Areas and Designated Land
In conservation areas, National Parks, AONBs, and World Heritage Sites:
- Outbuildings cannot exceed 10 square metres if placed on land between the side wall of the house and the boundary
- All other rules still apply
- Article 4 directions may impose additional restrictions
What Counts as an "Outbuilding"?
The same rules apply to all outbuildings incidental to the house, including:
- Garden sheds
- Summerhouses and garden rooms
- Home offices and studios
- Greenhouses
- Garages (detached)
- Workshops
- Gym/yoga studios
- Saunas and hot tub enclosures
- Carports
The total footprint of ALL these structures (plus extensions) counts towards the 50% garden coverage limit.
The "Incidental Use" Question
Your shed must be "incidental to the enjoyment of the dwellinghouse." This covers a wide range of uses:
Permitted uses (no change of use):
- Storage (tools, garden equipment, bikes)
- Home office/study
- Art or craft studio
- Home gym
- Music practice room
- Games room
- Workshop
Uses that may need permission:
- Running a business that involves customers visiting
- Dog grooming or similar commercial activity with clients
- Renting out as separate accommodation (Airbnb etc.)
- Any use as independent living accommodation
The line between a home office and a commercial business is blurry. HMRC and planning treat this differently. For planning purposes, if the use doesn't change the character of the property and doesn't generate traffic, noise, or other impacts, it's likely incidental.
Building Regulations
Most garden sheds don't need building regulations approval. Detached buildings are exempt if:
- The floor area is less than 15 square metres and contains no sleeping accommodation
- The floor area is 15-30 square metres, contains no sleeping accommodation, and is at least 1 metre from any boundary (or constructed of substantially non-combustible materials)
Buildings over 30 square metres need building regulations approval.
Electrical installations in sheds must comply with Part P of the building regulations. This usually means having a qualified electrician install and certify any fixed wiring.
Foundations
A small garden shed typically sits on:
- Paving slabs
- A concrete pad
- Treated timber bearers on gravel
Larger outbuildings may need proper foundations. This isn't a planning issue but affects the practicality and cost of the project.
How to Check If You Need Permission
- Measure the height — including any base or platform the shed sits on
- Measure the distance to boundaries — if under 2 metres, max height is 2.5m
- Calculate total outbuilding coverage — add up all sheds, garages, extensions, etc.
- Check if PD rights are removed — look at conditions on previous planning permissions, or check for Article 4 directions
- Check if listed — any outbuilding in a listed building's curtilage needs consent
- Consider applying for a lawful development certificate if you want certainty — this costs £120
If you do need a planning application, the fee is £258 and decisions typically take 8 weeks. If a shed has already been built outside the PD limits, retrospective planning permission is an option. Check your local council's planning portal for Article 4 restrictions — e.g. Nottingham or Newcastle upon Tyne.
Common Problems
Shed on a Raised Base
If your shed sits on a raised base, platform, or decking, the height of the base counts towards the total height. A 2.4-metre shed on a 20cm raised base is 2.6 metres — over the 2.5-metre boundary limit.
Gradual Accumulation
Each new outbuilding adds to the 50% coverage total. A shed here, a greenhouse there, a summer house later — eventually you exceed 50% of the garden. The limit applies to the cumulative total.
Sleeping in a Shed
Turning a garden building into a bedroom, bedsit, or self-contained flat is a material change of use. It needs planning permission, and councils are increasingly cracking down on "beds in sheds" — particularly in London.
Pre-fabricated "Garden Rooms"
The growing market for pre-fabricated garden rooms, offices, and pods follows the same planning rules as traditional sheds. Marketing claims that they "don't need planning permission" are only true if they meet the permitted development conditions.
Enforcement
If you build a shed that breaches planning rules, the council can take enforcement action within 4 years of the breach. After 4 years, the structure becomes immune from enforcement.
However, if the use is unlawful (e.g., living in it), the enforcement period is 10 years from the start of the use.
Frequently Asked Questions
Can I put a shed anywhere in my garden?
Yes, provided it's not forward of the front of the house, not between the side of the house and a highway boundary, and meets the height and coverage limits. Within those constraints, you can place it wherever you like.
How big can a shed be without planning permission?
There's no specific floor area limit, but the shed (plus all other outbuildings and extensions) must not cover more than 50% of the garden. Height limits of 4m (apex), 3m (other roofs), or 2.5m (within 2m of boundary) also apply.
Do I need planning permission for a log cabin in my garden?
The same rules apply as for any outbuilding. If it meets the PD conditions (height, coverage, position, use), no permission is needed. If it's used as living accommodation, planning permission and building regulations apply.
Can I run a business from a garden shed?
A low-key home office use is generally incidental to the dwelling. If the business involves customers visiting, deliveries, noise, or other impacts noticeable beyond the property, planning permission for change of use may be needed.
Do I need my neighbour's permission to build a shed?
No. If the shed is permitted development, you don't need anyone's permission. You should still be considerate about placement — a tall shed blocking your neighbour's light can cause disputes even if it's lawful.
How close to the fence can I build a shed?
You can build right up to the boundary. But if the shed is within 2 metres of any boundary, the maximum height is 2.5 metres.
Does a shed need foundations?
Not for planning purposes. Practically, some form of level base is needed, but there's no planning requirement for foundations. Building regulations only apply to larger structures (over 15m² or 30m²).
