Separate cabin work from storage
Inside a twelve by eight cabin you enough length to put a desk or bench in one zone and storage in another. Wooden apex-roofed cabins keep the profile familiar, while the open layout lets you decide how the room works. Plan sockets and insulation before lining the interior, and put the building on a prepared base. The electrical installation guide is a useful early read.

Buying ready-made is about £1,198 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.

A 12 x 8 ft log cabin needs a firm, level base at least 12 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.

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 8.9 m², a log cabin this size is exempt from Building Regulations as long as nobody sleeps in it.
- Working from a cabin yourself is incidental use. Sleeping in it, or regular visits from clients or staff, can need planning permission. Electrics need a registered electrician under Part P.
