How Far Should a Shed Be From a Boundary?

How far should a shed be from a boundary?

There is no universal UK rule requiring every garden shed to stand a fixed distance from a boundary. In England, the distance matters because permitted development limits the overall height of an outbuilding to 2.5 m when it is within 2 m of the boundary of the house's curtilage. That is a height limit, not a requirement to leave a 2 m gap. Planning rules differ elsewhere in the UK, so establish which rules apply before fixing the position.

Start with the actual boundary and the shed's full footprint, including any roof overhang. Measure the shortest horizontal gap between them in millimetres, rather than measuring from a fence that might not mark the legal line. Record the proposed overall height as well as the gap. These two measurements give you a useful first check, but they do not establish planning permission or building regulations compliance on their own.

1. Establish which boundary and rules apply

Find your property documents and compare their plans with the features on site. HM Land Registry explains that title plans usually show general boundaries, not the precise legal line. A fence, hedge or wall can therefore be an unreliable measuring point if its position is disputed. Resolve a material uncertainty before ordering a shed or laying a base.

Confirm whether the site is in England, Wales, Scotland or Northern Ireland, then check your local planning authority's guidance. Also ask whether an Article 4 direction, planning condition or designation restricts permitted development at your property. A shed at a flat, or one serving a building that is not a house, may not benefit from the householder rules discussed here. Keep the response or guidance you rely on with your project records.

• Mark the boundary you intend to measure from on a site sketch.
• Note any uncertainty between the title plan and the physical fence or wall.
• Record the relevant planning authority and any property-specific restrictions.

2. Draw the whole shed before measuring

Use the manufacturer's external dimensions, not the internal floor area or a nominal product name. Mark the walls, roof projection, door swing, steps and any guttering on a scaled sketch. A 50 mm roof overhang reduces a measured wall-to-boundary gap by 50 mm on that side. Check the finished height from the ground level next to the building, taking account of the base specified for the product.

Measure the shortest horizontal distance from the proposed structure to the boundary at more than one point. Boundaries and fences may not be parallel to the shed, so a gap measured at one corner may be misleading. Write the results in millimetres and mark the closest point on the sketch. Leave room to verify the dimensions again after the base is set out but before it is built.

• Record external length, width and maximum overall height.
• Include roof edges, guttering and any projecting fittings in the layout.
• Measure the narrowest gap, not the average gap.

3. Check planning height and placement

For a house in England, government householder guidance says an outbuilding within 2 m of the boundary of the curtilage must not exceed 2.5 m in height to qualify under that permitted development condition. Other limits still apply, including restrictions on position, height and the amount of land covered by buildings. If the proposed shed fails a condition, check whether planning permission is needed rather than assuming that moving it a few centimetres solves everything.

Apply the 2 m check to the nearest part of the proposed building, using a conservative measurement where an overhang is involved. For example, moving a shed so its wall is just over 2 m away is not a dependable solution if its roof projects back inside that distance. Check the current official technical guidance and your authority's advice against the finished design. Do not transfer England's 2 m test to another UK nation without checking its own rules.

4. Check building regulations separately

Planning permission and building regulations address different questions. In England, the Building Regulations 2010 list an exemption for a detached, single-storey building with no sleeping accommodation and a floor area of no more than 15 m². A separate exemption covers a qualifying building of no more than 30 m² if it is at least 1 m from a boundary or is constructed substantially of non-combustible material. The 1 m figure belongs to that particular exemption test; it is not a universal shed setback.

Check the structure against the exact exemption conditions before relying on either threshold. A larger building, sleeping accommodation or a different construction can change the position, and work involving electricity may have separate requirements. Ask the relevant building control body if the exemption is uncertain. For a shed outside England, use the building standards or building control rules that apply where the property stands.

5. Choose a gap you can maintain

A legally possible position is not necessarily a practical one. Walk the proposed route with a tape measure and check whether you can reach the wall to treat timber, repair cladding or clear a gutter. Make sure the door opens fully and that you can carry the largest item you expect to store through it. Record the access gap you need for those tasks rather than adopting an arbitrary clearance figure.

Check where rainwater will go from the roof and base. Leave the boundary fence and neighbouring land accessible for maintenance, and avoid directing runoff onto a neighbour's property. Locate drains, inspection covers and any known underground services before excavating for a base. If space is tight, a different door position, roof form or shed size may work better than placing a larger model hard against the boundary.

• Test door opening and the route for bulky stored items.
• Plan access to wall finishes, gutters and the fence.
• Identify drains, covers, services and the route for rainwater.

Final verification checklist

Before buying, compare your dimensioned sketch with the current rules for your UK nation and any restrictions specific to the property. Confirm the external dimensions and height with the supplier; product photographs are not a reliable substitute for a dimension sheet. Keep copies of the guidance and any written advice you received.

Before laying the base, mark the complete footprint on the ground and remeasure its closest point to the boundary. Check the finished height, door clearance and maintenance access from that marked position. If the boundary or an exemption remains uncertain, resolve it with the appropriate professional or authority before construction starts.

• Boundary identified and shortest gap measured in mm.
• Planning position, height and property restrictions checked.
• Building regulations exemption or approval position checked.
• Drainage, door swing and maintenance access checked.
