In 2008, my wife and I moved out of a 2,500 square foot single family home into a 998 square foot apartment. This was only supposed to be a temporary arrangement so we weren't all that bothered about it. We had to put at least half our stuff in storage and use one of the rooms of the apartment to store the rest. In 2010, we moved to a bigger apartment with an extra bedroom that gave us a bit more breathing room because events beyond our control had conspired to keep us renting.
On January 16, we will be moving into our new home. When you include the basement, it has well over 3,000 square feet. Our stuff will finally come out of storage and there will be plenty of room to put everything. Our old house was built in the '50s with a somewhat idiosyncratic design that wasted much of the space; however, these new houses are tailored to the modern family and designed to make better use of the available space. In fact, this was an important factor in the decision to buy a new house instead of an older one.
