You know what? I'm kinda tired of hearin about "outdoor rooms" in the garden. When I'm outside I want to feel like I'm outside, and when I'm inside I want to feel like I'm inside. I think the term "outdoor living space" has outworn its usefulness.
I don't know, it just seems odd that you'd want "hallways" in your garden instead of grassy paths leading from one flowerbed to the next. I've seen garden "rooms" with free-standing glass windows and have a hard time understanding the concept of looking outside while standing outside.
I never really got into the "outdoor room" craze that a lot of landscape designers and home gardeners had, and still have. Some of these "rooms" don't look like a garden at all, what's the point? I mean there's what looks like real furniture in some of these "rooms."
But I reckon since we're all unique we each have our own idiosyncrasies. Several years ago I saw a garden down in Louisiana (or was it Mississippi?) that featured a tree with bicycles hangin from it. Makes you wonder about some folks don't it?
