House Hunting for a bass.

I've come to a point where it is in my best interest to buy a house. This is a big step in a person's financial life. Now, I've been doing a little research here and there to see what's best for me, but it always seems that I keep coming back to one requirement... where will the music room be? Yes, I'm concerned about many other elements of the house (the foundation, the roof, moisture problems, gutters, the basement, number of bedrooms, condition of the bathrooms and kitchen, et al.) but I still would like one room committed to music. It would be nice to have one place away from bedrooms where I can practice without waking the kids; a room where I can practice and create and also invite others to play as well. I guess I'll need to research sound proofing as well.
