Best Small Garden Sheds UK: A Buying Guide for Tight Spaces

If your garden is small, awkward-shaped, or you're trying to fit storage down a narrow side-return, the right shed size is usually smaller than you think and the material matters less than the access. A 5x3ft or 6x4ft wooden or metal shed suits most small UK gardens with a mower and hand tools, while a slim, tall shed or a sliding-door design works better for a tight side-return where a hinged door has nowhere to swing. Get the size and access right first, then choose the material.

What size small shed do you actually need?

On UK forums, the same argument comes up again and again: buy small and stay tidy, or buy the biggest you can fit and you'll never regret the extra room. Both camps have a point. One MoneySavingExpert forum user fitting a mower and hand tools settled on 7x5ft and called it "a good size shed". The honest answer is that even sheds that sound generous fill up fast, so it's worth being realistic about what's actually going in rather than what might one day go in.

These bands reflect the specific sheds featured in this guide, not the full range. Prices vary more widely across the whole small-sheds category depending on extras like windows, foundation kits and lockable doors.

If you're only storing a mower, a few tools and some pots, don't feel you need to go beyond 5x3ft. If you know bikes, a workbench or seasonal furniture are coming too, size up to 6x4ft rather than buying twice.

Which material works best in a small space?

We've covered the full wood vs metal vs plastic trade-offs in our metal vs wooden vs plastic garden shed guide, so we won't repeat that here. What's specific to a small shed is ventilation and maintenance access. A small space heats up and holds condensation faster than a large one, so whichever material you choose, plan for a vent or gap rather than sealing it up completely. One MoneySavingExpert user described the inside of their shed's walls going wet after heavy rain, "as if they were absorbing rain water." In a separate MoneySavingExpert thread about shed condensation, another user summed up the underlying issue plainly: "it's almost impossible to make it dryer inside than outside." Ventilation, not the material, is what actually solves this.

Wood needs occasional treating, which is awkward if there's no room to get round the back of it. Metal and plastic avoid that but can trap condensation if the door is kept shut all the time. If access for maintenance is tight, a metal or plastic shed with a vent is usually less hassle long term than a wooden one you can't reach three sides of.

How do you fit a shed into a narrow side-return or tight corner?

This is the part most buying guides skip. If your shed has to go down a side-return, past a gate, or into a corner where a hinged door has nowhere to swing, the door style matters as much as the footprint. A sliding door avoids the swing-clearance problem entirely, and a slim, tall shed uses less floor width for the same storage volume as a squat, wide one.

Before you buy anything, measure the narrowest point of the actual route in, not just the final spot, including any gate width and the reach of a bin day or delivery. Several forum threads on plastic and metal sheds blowing over in exposed spots are also worth a mention here: a shed wedged into a sheltered side-return is at less risk than one standing free in an open garden, but it's still worth pinning it down (see the base section below).

Best for narrow footprint

Tall Narrow Wooden Shed with Shelves, 84x52x188cm

Do you need planning permission for a small garden shed?

In most cases, no. Sheds usually fall under permitted development, meaning no planning application is needed, provided the shed is single storey, sits behind the front of the house, and (with other outbuildings combined) doesn't cover more than half the garden. Because small sheds rarely get anywhere near those limits, this is one area where going small genuinely removes a worry that larger sheds and outbuildings can run into. Rules do shift depending on your exact boundary distance and roof height, and differ if you're in a conservation area or a listed building, so if you're at all unsure, check the government's own guidance before you buy rather than after. We've written a full breakdown, including the boundary and height thresholds, in our guide to how big a garden shed can be without planning permission. For the official rules directly, see the Planning Portal's outbuildings guidance.

Do you need a base for a small shed?

Yes, even a small one. A shed sitting directly on soil or grass will hold damp against the floor and can shift or lean over time. Paving slabs on a level, compacted surface work for most small sheds, and a plastic grid base kit is a lighter, quicker option if you don't want to lay slabs. It's also worth pinning the shed down, not just resting it in place. One MoneySavingExpert user's metal shed blew over because the screws fixing it to its base were too small; another, on the same forum, weighted a plastic shed down with paving slabs and its stored contents and reported it had "never moved yet." Both approaches work if you do them properly, but skipping anchoring altogether is the mistake to avoid.

If you'd rather not lay a full slab base, Opal's plastic grid shed base kit (from £69.99) sits straight on levelled ground and drains freely, and comes in sizes to match most small sheds.

Frequently asked questions

What's the smallest practical garden shed?

For genuine tool storage rather than just a bin store, most people find anything much under 4x3ft too tight to use comfortably. A slim, tall design can go narrower in width while still holding a useful amount, because it uses height rather than floor area.

What size shed do most small gardens actually need?

For a mower plus hand tools, 5x3ft is commonly enough. If you'll also store bikes, a workbench, or garden furniture over winter, 6x4ft is the more realistic size, since even sheds that sound generous tend to fill up faster than expected.

Should I buy a small shed or a garden storage box?

A storage box suits cushions, small tools or a single mower and needs no base or planning consideration at all. Once you need to store several tools upright, a bike, or anything you want to walk into rather than reach into, a small shed is the better fit.

Will a small shed blow over in the wind?

Any lightweight shed can shift in strong wind if it isn't secured, regardless of material. Anchoring it to a base, whether that's screwed-down fixings on paving or ground anchors on a plastic grid base, solves this in most gardens.

Does a small garden shed get damp inside?

It can, and it's usually a ventilation issue rather than a fault with the shed itself. A small, sealed space holds condensation faster than a large one, so a vent, gap, or occasionally propped door on dry days makes a bigger difference than the material you choose.

Do I need planning permission for a small shed in my garden?

Almost never, provided it's single storey, behind the front of the house, and doesn't take your total outbuilding coverage over half the garden. See our full guide linked above for the exact height and boundary rules.
