A hundred and twenty square feet is the point where a shed stops being storage and starts being a room. The 10x11.5 Stronghold is the model people buy when the last shed filled up in eighteen months — deep enough to keep a workbench along one wall and still park the mower, with floor left over.
The extra three feet change everything
Depth is what you actually run out of. At 11.5ft you can store long items — ladders, timber, a folded gazebo — down one side without blocking the doorway. The one-piece floor is moulded flat and takes the weight of a ride-on without packing or boards underneath.
Weather it was designed around
Steel-reinforced double-wall resin, 46mph wind rating, 150kg/m² snow load. Graphite colour moulded through the panel, so it doesn't fade to grey chalk and never needs treating. Roof skylights bring in enough daylight to work by.
Before you order
Measure twice — this is a large footprint and it wants a level base. It arrives across several numbered cartons, often across two days. Two people and an afternoon will get it standing; three makes the roof section easier.
Footprint: 10ft x 11.5ft · Internal: 120 sq ft · Warranty: Keter limited 10-year
Delivery
Free delivery on every order, with no minimum spend — 3 to 5 working days across mainland UK, 4 to 6 business days across the continental US. We dispatch within 2 working days of your order.
Large sheds travel kerbside on a pallet and arrive in several numbered cartons — these don't always turn up on the same day. Check the box numbers against your manual before you start building.
Returns & warranty
You have 30 days from delivery to return anything unused, unassembled and in its original packaging. Return postage for a change of mind is arranged by you; there is no restocking fee.
If something arrives damaged or parts are missing, don't send it back — email us photos and your order number and we'll sort it. Every product here is genuine, so the full manufacturer warranty applies.
Assembly & base
Every model ships flat-packed with printed instructions and the fixings you need. Two people and an afternoon covers most builds; the larger sheds are a weekend.
All of these need a flat, level base — concrete, paving slabs or a timber frame. Get the base right before delivery day and the build goes twice as fast.

Common questions
How long does delivery take?
We dispatch within 2 working days. Mainland UK delivery takes 3 to 5 working days after that; the continental US takes 4 to 6 business days. You'll get a tracking number the moment it leaves the warehouse.
Do I need a base?
Yes. Every shed on this site needs a flat, level base — concrete, paving slabs or a timber frame — and the base should be the same size as the shed's floor or slightly larger. Get it ready before delivery day.
Do I need planning permission?
In most UK gardens a shed falls under permitted development, but there are limits on height, position relative to boundaries, and how much of the garden you can cover. In the US, rules vary by city and county, and some neighbourhoods have their own restrictions. Check locally if you're unsure.
Is it really the genuine brand?
Yes. We only sell Keter and Patiowell, and every unit comes in its original manufacturer packaging with the full manufacturer warranty. No imitations, no grey-market stock.
What if I change my mind?
You have 30 days from delivery. The item needs to be unused, unassembled and in its original packaging. Email us and we'll send return instructions — return postage is arranged by you, and there's no restocking fee.
