If you’re building a garden room, then you need to know the construction lingo for dummies.
Here is the definitive list of construction terms to help you when building your own garden room.
When beginning my research into the construction of a garden room, I struggled with some of the building terminology which was flying around forums and sites but experienced builders. I found myself regularly returning to a few websites which had a great ‘dictionary’ of construction terms which really helped – so I’ve recreated those pages, and cut the list down to the main ones you’re going to come across when researching your own garden room project. So without further ado, here is the definitive list of construction terms for dummies (like me)…
