Everything you need to know
The 12x8 wooden shed base spans W-354cm x D-241cm, a generous platform sized for large sheds, workshops and garden offices that demand a stable, evenly supported floor. At over three and a half metres wide it keeps sizeable buildings square and true.
You control the finished height by selecting from three timber depths - 38x63mm, 38x89mm or 38x138mm - which is especially useful across bigger footprints where ground levels can vary. Pre-assembled base sections take the hard work out of construction; rather than cutting and building a frame, you connect the ready-made parts together and move straight on to positioning your shed.
Suitable for both novices and seasoned DIY enthusiasts, each base comes complete with all the required fixtures and easy-to-follow instructions so you can put your personal touch on the finished project.

Shed Base - what actually matters
Anything that lives outdoors in the UK has to cope with sustained damp rather than dramatic weather. Drainage, airflow and how the unit sits on the ground do more for its lifespan than the headline material. If you want the longer version, read the full range.
Looking after it
- Re-coat with a clear or tinted exterior wood treatment every two to three years.
- Keep the base clear of piled soil and leaf litter so the timber can dry out.
- Check fixings once a year and nip up anything that has worked loose.
Delivery and returns

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.
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.
