Under 15 m², as long as nobody sleeps in it
Worked out by ShedBuilder from the measured size and today's prices. Slab and concrete figures cover the footprint only; add a margin if you want a path around it.
The base you will need
An 8 x 4 ft shed needs a firm, level base at least 8 x 4 ft. Most guarantees depend on it. A concrete slab or paving lasts longest. A plastic grid filled with gravel is quicker, drains well and needs no concrete.

Planning permission and Building Regulations
- Most garden buildings do not need planning permission in England and Wales if they are behind the front of the house and, with any other outbuildings, cover no more than half the garden.
- Within 2 m of a boundary the whole building, base included, must be no taller than 2.5 m. Further away, the limit is 4 m for an apex roof or 3 m for other roofs, and the eaves must stay under 2.5 m. Check the height on the product page before you order.
- At about 3.2 m², a shed this size is exempt from Building Regulations as long as nobody sleeps in it.
