We have a 1500 sq ft house with 2 kids. We have 3 bedrooms so each kid has their own room. We also have 2 added sunrooms off each end of the house, one of which I use for my office. Part of our garage has also been converted into a gaming area for my son and his friends. We don't want anything bigger. It really is the perfect size for our family. We all have our own space when we need it but still close enough so we aren't totally alienated from each other.
