The honest UK guide to garden offices
Compare 81 kit log cabins from 5 UK sellers side by side – size, wall thickness, glazing, floor and what the price really includes – or find checked local garden room builders.
What we promise
- Every figure comes from the seller's own product page, with the link and the date we checked it.
- If a seller doesn't say something, we show “not stated” – we never fill gaps with guesses.
- We haven't tested these buildings, and nobody pays to be listed or ranked.

Thin walls are cheap for a reason

Would rather someone else built it?
A made-to-measure garden room costs more than a kit but arrives insulated, wired and finished. We list local firms with the facts they publish themselves – where they're based, the area they cover, prices if they give them, and their guarantees.
