Just to say, my point with the rowhouses was serious Those 32 are filled to capacity with 30 people living in each of them. I'd guess they are at least 200 m^2 considering 90 people could live in them. Uncomfortably yes, but they must at least have had sufficient space for people to lay down and sleep, as well as keep a few posessions around. Meanwhile a goodsized peasant home for a family with children in the middle ages was around 40 m^2. As a starter home a quarter or a fifth of a longhouse isn't bad at all.
