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.

Build one yourself instead?

Build a timber-framed summerhouse yourself£2,497Materials at today's merchant prices, inc VAT

Buying ready-made is about £1,368 cheaper than the materials to build it yourself. Factory-made buildings use lighter framing and thinner boards than a self-build, so building your own makes sense if you want it heavier-duty or a custom size.

The self-build figure uses our standard specification for this type of building, priced from a full materials list: framing, floor, cladding, roof, door and fixings. It excludes tools and your time.

The base you will need

An 11 x 7 ft summerhouse needs a firm, level base at least 11 x 7 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.

Protect the timber

Even pressure-treated buildings last longer with a coat of treatment every couple of years. Do the first coat before it goes up, while you can reach every board edge.
