Where you off to? Anywhere exciting?
This guy owned a saw mill so he built the cabin we were staying in by hand as a means to get some extra income. Was pretty cool and he was a very good host.
Off to Cornwall this time. Been to Devon and Somerset the last few.
Stayed in a similar sort of thing to what you describe, called Jacksons Cabin, was on canopy&stars, not airbnb that one. Built the place himself in their garden, completely separate to the house and blocked off by a large hedge so private.
Then we stayed in a converted old barn over Glastonbury way; https://www.airbnb.c.../rooms/15229339
