Plan a substantial garden room

Sixteen by eight feet gives a generous room that can combine seating, a desk and hobby storage, but its length needs a deliberate layout. Wooden buildings use apex roofs. Mark the door, furniture and circulation route on the ground first, then arrange a suitable base. Check the site against the planning information before ordering, using the UK planning guide.

We earn a commission from the retailer if you buy through links on this page, at no extra cost to you. It never affects which summerhouses we show or how we compare them. Prices were checked on 7 November 2026 and may have changed, so check the retailer before you buy.

Buying ready-made is about £2,157 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

A 16 x 8 ft summerhouse needs a firm, level base at least 16 x 8 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.
