Everything you need to know
At W-590cm x D-300cm, the 20x10 wooden shed base is one of the largest in the range - a near six-metre platform for extensive sheds, garages and garden workshops. A base of this scale spreads the load and keeps a big building level from end to end.
- Sized for 20x10 sheds and large outbuildings
- Choice of 38x63mm, 38x89mm or 38x138mm timber
- Adjustable finished height for uneven plots
- Pre-assembled sections join together on site
- Fixtures and instructions supplied
The pre-made sections are a real advantage over such a long run: you connect the parts together instead of building an entire frame by hand, so even a large base stays achievable for keen DIYers. Set the timber depth to match your ground and finish it your way.
Every measurement, every material.

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.
