We are at 2180 which is plenty of room, not counting the basement. We have three bedrooms and two and a half baths.
Daughter will be moving out soon so it is really more room then we need at this point and more then I care to vaccum, dust, mop, keep clean, heat and cool.
The living room is hardly used, it just looks pretty.
We spend most of our time in the kitchen, study or family room.
