Our house has some "low eave" space, where the angled roof comes down too low for a normal-height roof. One one side of the house it's set up as storage, but on this side it's entirely closed off:

I could open up the end, insulate it, put in a floor, walls, mattress, lighting, ventilation, and ladder, and make it available as a sleeping space. It would be a lot like a capsule hotel, though with a bunk-bed height ladder.

Now, if I were visiting someone I would much prefer to sleep in a space like this than in the living room, but I wanted to check to make sure I'm not being weird here? Do other people also value quiet, isolation, and darkness, more than space and ease of exit? People of course could sleep in either place, so it's fine if some people would prefer one vs the other, but if no one aside from me would be interested in sleeping in a loft then I probably shouldn't build one.
