It would be like a mini apartment situation. That might be more condusive to peaceful living. Too much togetherness - even with the best of friends or family can eventually wear on each others nerves. It would be sad to see friendships strained. Separate living quarters would give everyone their own "space", yet you would have communal living spaces also. For folks that aren't hermits like myself, that is a neat concept.
This intrigues me! If, in 5 years, you could be close to debt free, it'd sure take that load off your back! If you could make the house to a point that you could have 2 kitchens, maybe, or something like that where it's divided enough to get the privacy you want....I'd do it in a heartbeat! Yes, I like my privacy, but with some who are strapped for money, this seems like it could work out well! We actually have some friends who are building a home right now. There will be two families living there, and for just the same reasons! I agree with having the ability to separate yourselves, cuz after awhile it DOES get harder! I wouldn't give up on the idea so easily, I'd keep researching it! As someone said, we're all already weird because we homeschool. This isn't any weirder than that!
