About this product

Everything you need to know

Built for substantial buildings, the 15x10 wooden shed base measures W-442cm x D-300cm - a large-format foundation for oversized sheds, summerhouses and workshops. Across a footprint this size, a properly level base is what keeps doors aligned and floors firm for years.

Three timber depths are available - 38x63mm, 38x89mm and 38x138mm - so you can build up the height needed to compensate for sloping or uneven ground beneath a large structure. The base is supplied as pre-assembled sections, meaning the bulk of the work is simply connecting the ready-made parts together rather than framing from scratch.

Whether this is your first build or you tackle DIY regularly, everything is included: all the necessary fixtures and clear, easy-to-follow instructions to help you complete and personalise your project with confidence.

Common questions

Everything buyers ask before they order.

How long does assembly take?

Assembly time depends on the size — storage boxes take 15–45 minutes, benches around 30–60 minutes, sheds and bin stores 2–3 hours with two people. Exact figure for this product is in the Full specification table below. Tools needed: a screwdriver and a spirit level. Prefer someone else to build it? Book a verified Tasker via Taskrabbit.

Do I need a base or level ground?

A level, solid surface gives the best result for sheds and larger storage units — concrete slab, paving flags, or a pressure-treated timber base all work. Storage boxes sit on any level paved or decked surface. If the ground isn't level, panels won't line up cleanly and the unit won't be fully weathertight.

When will my order arrive?

Standard UK mainland delivery is 5–7 working days, tracked. Free over £100. You'll get a dispatch email with a tracking link. We don't currently ship to Channel Islands, Isle of Man, Scottish Highlands & Islands, or Northern Ireland — see our delivery page for the full breakdown.

What if something arrives damaged?

What's my consumer protection?

You have full rights under the UK Consumer Rights Act 2015 (satisfactory quality, fit for purpose, as described) and the Consumer Contracts Regulations 2013 (14-day right to cancel from receipt). See our returns page for how the cooling-off period and refund timing work in practice.
