I live in a little cabinish place by ocean about 110 or 120 square feet,but sloped in..shaped like windmill. There is an upper floor..two actually..one a real attic...that I don't use except for storage..if my sister needs to stay here she can since she has lost her job...two will be tight but doable. I think my ancestors could have fit 30 people into it and would have been delighted with the plumbing. It is fine for one person, maybe two. mg
