How we score. The value score is our own sum from the listed specs and Shedstore's price. It is not a customer review and we have not tested the products. For a shed: 45% is price per square foot against other sheds, 25% is guarantee length, 20% is features (floor, windows, lock, double doors) and 10% is any saving off the RRP. Bases are scored on price per square foot and guarantee, storage boxes on price per litre, guarantee and lock. Give us your space and it becomes a match score that also rewards the products that make best use of it.
10x8 plastic sheds are for gardens that have outgrown a standard shed. At 10ft by 8ft you get room for a ride-on or wide mower, several bikes, a wheelbarrow and the garden furniture, with space left to walk in. Resin and polycarbonate walls won't rot, never need painting and keep their colour for years.
This range covers the Keter Stronghold 10x8, its 8x10 and 8x11 rivals, plus 11x9 and 11 x 7'5 sheds for a little extra room, all sold by Shedstore. Want more space still? See our large plastic sheds. A bit less? Try 8x8 plastic sheds.
A 10ft x 8ft shed gives you about 7.4 square metres of storage space, roughly double a 6x4. That's the jump from a tool cupboard to a real garden storage shed. You can park the mower without lifting the bikes out first, keep a workbench along one wall and still close the doors on everything.
It's the biggest footprint most suburban gardens can take without the shed taking over. It sits along the back fence of a typical semi with room to spare, and it's still small enough to fall under permitted development in most cases (see the planning section below, as two sheds here are just over the 2.5m height limit for boundary spots).
Going plastic makes even more sense here than on a small shed, because there's more wall to look after. A large plastic garden shed gives you:
Here's every storage shed in this range side by side. Sizes are the makers' figures including the roof overhang, width first. Prices change daily and the grid above always shows Shedstore's live price, so they sit in bands here.
| Shed | Size (ft) | Size (m) | Ridge height | Door width | Floor | Snow load | Guarantee | Price band |
|---|---|---|---|---|---|---|---|---|
| Palram Canopia Rubicon | 8' x 10' | 2.37 x 3.03 | 2.35m | 1.30m, ramp | Yes | 80kg/m² | 12 years | £1,000 to £1,300 |
| Palram Canopia Yukon | 11' x 9' | 3.32 x 2.71 | 2.52m | 1.48m, ramp | No (steel base frame) | 100kg/m² | 15 years | £1,000 to £1,300 |
| Factor | 8' x 11' | 2.57 x 3.32 | 2.43m | 1.39m | Yes | 75kg/m² | 15 years | £1,300 to £1,600 |
| Stronghold | 10' x 8' | 3.05 x 2.43 | 2.51m | 1.53m | Yes | 150kg/m² | 10 years | £1,300 to £1,600 |
| Palram Canopia Yukon with WPC floor | 11' x 9' | 3.30 x 2.70 | 2.52m | 1.48m, ramp | Yes (WPC) | 100kg/m² | 15 years | £1,600 to £1,800 |
| Newton Plus | 7'5 x 11' | 2.30 x 3.50 | 2.46m | 1.39m | Yes | Not stated | 15 years | £1,600 to £1,800 |
| Newton Plus (reverse apex) | 11' x 7'5 | 3.50 x 2.30 | 2.46m | 1.39m | Yes | Not stated | 15 years | £1,600 to £1,800 |
The Rubicon is the cheapest way into this size and the lightest to handle. The Stronghold is the toughest, with the widest doors and the highest snow rating. The Newton Plus pair cost the most but give the most storage space, about 8 square metres, in a slim 2.3m depth.
The Stronghold is the only true 10ft x 8ft shed here, and it's the toughest. Its walls are Evotech resin panels with a wood-effect finish over steel reinforcement, and the steel-reinforced apex roof is rated for up to 150kg of snow per square metre, double the Factor's rating. It measures 3.05 x 2.43m including the overhang and 3.00 x 2.38m at the base.
The double doors are the widest in the range at 1.53m, and 1.84m high, so a ride-on mower goes straight in. They close with a 3-point locking system and an ergonomic handle you can open one-handed. A full-length skylight and transom windows light the inside, and a heavy-duty floor is included. It carries a 10 year warranty. The grey version is shown here, and there's a brown one too on Keter's site. Our Keter Stronghold sheds page has the other sizes.
The Rubicon is the budget pick and a different kind of storage shed. Its dark grey walls are 10mm multi-wall polycarbonate, the hollow-chambered sheet used for conservatory roofs, on a reinforced aluminium frame. It's 2.37 x 3.03m with a 2.35m ridge, so it's the lowest model here and can go right up to a fence.
The shingle-style skylight roof lets soft light in but stays opaque from outside. Doors open 1.30m wide with a ramped entrance, and the polycarbonate floor has an anti-slip finish. Palram says it was wind tested to 115km/h (71mph). It must be anchored to a solid, level base, and a free Hilti screw anchor kit is in the box. At 82kg packed it's also far easier to carry round to the back garden than the others. Warranty: 12 years.
The Factor is the Keter 8x11 shed, a little longer than the Stronghold. Inside you get 2.37 x 3.12m of clear space under a 2.43m apex. The walls are steel-reinforced resin with a beige wood-effect finish, and a heavy-duty resin floor is included. One framed window fits on either side, there's a skylight, and vents are placed to cut condensation. Two shelves with brackets are included.
It's rated for 75kg of snow per square metre, gives it a 15 year warranty and puts the build at about four and a half hours for two people. Compare the smaller Factor sizes on our Keter Factor sheds page.
The dark grey Yukon is the widest shed here at 3.32 x 2.71m, with the biggest doors after the Stronghold at 1.48m and a low threshold ramp. Walls are commercial-grade 10mm polycarbonate on an aluminium frame, and the 0.9mm shingled skylight roof has built-in guttering. It's rated for 100km/h winds and 100kg/m² of snow, with a 15 year warranty.
It comes two ways. The standard Yukon has no floor, just a galvanised steel perimeter base, so you build it straight onto concrete or slabs. The premium version adds an 11mm wood polymer composite (WPC) floor that's waterproof and slip resistant. Both are 2.52m at the ridge. See every size in our Palram Canopia sheds collection.
The Newton Plus gives the most garden storage here, about 8 square metres, in a narrow 2.3m depth. That makes it the one for a long, thin side return or a strip along the back fence. The 7'5 x 11' has its doors in the short end. The 11' x 7'5 has a reverse apex, which puts the doors on the long side so you can reach the back corners easily.
Both are grey, weather resistant double-wall Evotech resin with steel reinforcement, a heavy-duty floor, two Victorian-style windows and a full-length skylight. The modular layout lets you choose where the doors and windows go. The lockable doors open 1.39m wide and close with a lever. Both carry a 15 year guarantee. Other lengths, up to 7'5 x 17', are on our Keter Newton Plus sheds page.
A 10x8 shed and an 8x10 plastic shed have the same footprint turned through 90 degrees. Makers usually quote the front width first, so the Rubicon 8' x 10' is 2.37m across the front and runs 3.03m back. The Stronghold 10' x 8' is the other way, 3.05m wide and 2.43m deep.
Only got a long, narrow strip? Look at 6x10 plastic sheds. If the space is square, 8x8 plastic sheds may fit better.
As a guide, a shed this size takes all of this at once:
Plan the walls first. Good garden storage is about using the height, not just the floor. Moulded panels can't take screws like timber, so use the shelves and brackets made for them. The Factor includes two, and the Yukon takes Palram's own shelving kits. More ideas are on our shed shelving page. Storing mainly bikes? Our plastic bike sheds page has smaller options.
"Plastic" covers two quite different materials in this range.
Against a wooden shed, both win on maintenance and rot. A timber shed is easier to fix shelves into, but it needs treating every year or two. A metal shed is often cheaper at this size but can dent and runs damp with condensation. Heavy duty HDPE sheds from Lifetime rank well for this search too, but Shedstore doesn't sell them, so they're not listed here. For outdoor storage that lasts with no upkeep, plastic is hard to beat. Our plastic vs wooden shed guide covers the trade-offs, and the strongest models are on heavy duty plastic sheds.
Five of the seven sheds here include a floor: the Stronghold, Rubicon, Factor, both Newton Plus sheds and the premium Yukon with its WPC floor. Only the standard Yukon comes without one. All of them are on our plastic sheds with floors page.
A floor isn't a foundation, though. Laid over soft lawn it will sink unevenly, and once the frame twists the double doors stop lining up. Every shed here needs a firm, level base.
Make the foundation flat, level and at least as big as the shed's footprint at ground level. Concrete, paving slabs or a gravel-filled plastic grid kit all work. Here's how this range lines up with the ProBASE kits Shedstore sells:
Each ProBASE set is 500mm recycled plastic grids filled with pea gravel (bought separately). Compare them on our 10x8 shed bases page. On a sloping plot, adjustable shed bases lift the shed level without digging.
All seven arrive flat packed with full instructions and no cutting or sawing. Panels this big catch the wind, so build on a dry, still day with two people. The Factor takes about four and a half hours. The Palram Canopia sheds use a sliding panel system. The heaviest boxes weigh 184 to 196kg, so check delivery access and plan where the courier can leave them. Delivery is by courier, so check the delivery charge, lead time and any postcode exclusions on each Shedstore product page before you order.
A big storage shed often holds the most expensive kit in the garden, so security matters more. Every model here has lockable double doors with a padlock fixing, but none comes with a padlock. The Stronghold's 3-point locking system is the strongest. Fit a closed-shackle padlock, keep the shed anchored to its base and chain bikes and the mower inside. The Palram Canopia panels stay opaque from outside, so nobody can see what's in there. Alarms and extra locks are on our shed security page.
Usually not. In England, garden sheds fall under permitted development if they meet a few rules. The one that matters most for big sheds is height: within 2m of a boundary, an outbuilding can't be taller than 2.5m. Away from the boundary, a shed with an apex roof can be up to 4m.
The shed also can't sit in front of the house, and outbuildings can't cover more than half the garden. Listed buildings and conservation areas have tighter limits, and Wales, Scotland and Northern Ireland have their own rules. The Planning Portal guide to outbuildings sets out the full rules for England. Full specs and manuals are on the makers' sites at Keter UK and Canopia by Palram.
About 3.05 x 2.44m. The Keter Stronghold is 3.05 x 2.43m including the roof overhang and 3.00 x 2.38m at the base. That's around 7.4 square metres of storage.
For most gardens the Keter Stronghold. It has the widest doors, the strongest roof and a floor included. On a budget, the Palram Canopia Rubicon 8x10 costs less and is easier to build. For the most floor in a narrow space, choose the Newton Plus.
Yes. The Stronghold includes a heavy-duty floor, as do the Factor 8x11 and both Newton Plus sizes.
Makers back these sheds for 10 to 15 years, and their panels won't rot or rust. On a level base, kept clear of heavy snow and leaves, a well-built shed should outlast its guarantee.
No. Lawn is too soft and uneven for a shed this big. Lay concrete, slabs or a gravel-filled grid kit first.
Any closed shed can. Ventilation is the fix. The Factor, Stronghold and Newton Plus have vents built in, and a dry base and dry tools help. Keep cushions in a sealed box off the ground.
Keter's resin sheds are heavier, look more like timber and have windows. Palram Canopia's polycarbonate sheds are lighter, cost less and let daylight in from above. Compare both ranges on our Keter sheds and Palram Canopia sheds pages.
