Some homes that you visit might be more friendly than other homes are. From my experience I can say that the more attention to detail a homeowner puts, the more friendly his house has chance to be. One of the ways to make a home a friendly home is to design it and build it from scratch. If somebody wants to build a house from scratch, he will need floor plans to make it possible. You do not get a chance to design your house every day. When you do, you need to make sure that you do it at least the right way. My advice is that you take as much time as you think you need.
