I think this stuff is really interesting. I think the Tiny house is the extreme end of the movement and I don't think a lot of people can go this extreme but it's really more about the lesson learned.
I live in a 2800sf 4/3 house on 3.5 acres. I read these stories and am very impressed. We are contemplating a move closer to town so that we can put our son in a specific school and this makes me think a lot about what we REALLY need. Maybe stepping down to a 1,800 sf house is a 'Tiny' house for me. Most people move up in size every time they move, this makes me think hard about moving down in size.
One problem I have is that houses today have so much space that is literally worthless. Like dinning rooms and formal living rooms. I HATE that. A dining room is the worst. Who eats in there? Maybe once a year for the holidays. So I am paying per sf, taxes, insurance, heating and cooling a room for once a year use?
I am also thinking the same way about guest rooms. We have them, we furnish them, and barely ever use them. Maybe forgo the guest rooms and stick a pull out couch somewhere.
All things to think about. I just know right now I have too much house, maintenance, payment, bills. I want to get down to a leaner fighting weight.
