What type of home are you building? How big is your family? You need to make a list of things that are important to you to give you an idea of what type of floor plan would be best.

You should be able to find house plans online to help you get an idea of what you'd like. Also, go to open houses on the weekends if you have time so you can look at as many homes as possible to get an idea of what you like, and what you don't like.
