Kirsten, my family of seven (two adults, 5 children under 10) lived in 900sq feet. Two bedrooms, 1 1/2 baths. 5 acres. Detached garage.
We moved to 1600 sq ft ranch style house w 17 acres and added a chicken coop and a pole barn, and baby but subtracted an adult within the first year.
The bigger space means we have to be more aware of adding clutter. Seven people can have too much, especially since we also homeschool. We clear down to the essentials when we reach an obvious too much stuff point. We are about to do it again!
I miss my tiny house. The space was better utilized. I had more kitchen cabinets. There was occassionally excess stuff without a spot. But only temporarily. We could be close but apart.
