Frugal and Energy Efficient Living

I am moving from 3600 feet into 1600 square feet in a few weeks and worried about how it will work. The reality is that with two people you can make do with even smaller spaces than that, if you organize and plan correctly. I think you need light, air and the ability to close a door on each other when needed. We found we really only used three or four rooms plus the kitchen and bathrooms on a regular basis anyway. I don't know if I would be able to handle a really small place because I do like my alone time and I need that door quite a bit as my SO is a yacker and if I am within eyesight he is talking.

With a good design I probably could get down to 800 square feet but it would need a great design and solid doors.....maybe with a lock...
