How thick are garden room walls?
Spend a few minutes online looking at garden room designs, and you could be forgiven for thinking that some companies’ rooms look just like those of other companies; the only difference is the price tag.
If you could x-ray the designs and look under the external cladding, you would quickly realise that the wall structure is very different between companies.

Design choices to ensure your garden room is warm in winter?
When planning a garden room, the design choices you make for the core structure will affect how warm it is in winter.
While you will initially pay more for a multi-layer garden room structure compared with other types of garden building, you will reap dividends in the long run.
