My own home is 900 s.f. with two bedrooms and a bathroom. We have lived there for 9 years. There are occasional mini-crisis over the one toilet. and I would like a large kitchen than the 9 foot "new york kitchen" we have. Also a mudroom would be nice. We will add on someday and double the size of the house. I rarely let clients see my home because after moaning to me about how their own 2000 s.f. house is way too small and they need more space, they might get embarrassed and "disappear" We invested in a really good sleeper sofa - it is our guest bedroom.
