>>160497I mean, if you like the idea and have the money/opportunity to do it, i'd say go for it. Though, if you're going to build it in an already existing house, you might want to properly think and plan out how you want it be, and what changes you'd need to make in the house. Winging it might not the best thing to do when it comes to making something you're going to be spending most of your time with.
Another option, that would probably be less work, is to just find a small one room apartment. But if you don't want to live completely independently i guess that's not really the right option.
There's also the option of finding a house with like an independent guest cabin or something along that line. Then you'd have like a bedroom and bathroom, maybe even a stove, for yourself, but the main house would only be a few steps away.
Anyway, just a couple of options to consider if you want.
Personally, i've always been found of small one room solutions that maximizes space usages. Like, a 2x2x2 room that has everything you need, but efficiently placed or packed away to maximize the use of the small space you have, but has everything so you can live completely independently. I'm living in a normal one room apartment right now and my parents would freak out if i actually "downgraded" into such a place instead of moving to a "real" house with a yard and such and making a family as a next step, so i've left that idea aside for now.
