Building a new home - the beginning to a new adventure

Dave has been trying to convince me that we needed to move into a bigger home for a few years. Right now, our house is about 2,400 square feet (downstairs and upstairs). Before we had children, the house was plenty big because we could utilize all of the closets. Now that the kids are getting older and need a little of the space, I realized it may be time to move into something a little bigger. However, after looking at a few houses, I wasn't convinced. Did I really need something bigger, could we make our existing home work?

I kept going back to the house that I grew up in. It was about 1,000 square feet on the main floor and the basement isn't finished. My parents raised all six of us there (I have two sisters and three brothers). They still live in the house today and it's plenty big now that we are all gone. I mean, the house had portable closets, not built in ones. It was only a three bedroom house, my parents had one room, the girls had another and my brothers had the third. I kept going back to this thinking, do we REALLY need a new home? I survived, not happily at times, but somehow we managed with the tight quarters.
