I don't know about "going big" as I don't feel like a big shop, but I do lease our building and have 3 employees - would very much like to own my own building but its just too cost prohibitive right now. I think if I was doing everything myself and didn't have employees I would stay at home if I had access to a building (which I don't) to keep overhead low. That said, I have seen friends and family running businesses out of their home and I don't think I could deal with it. My home is my "safe zone" to get away from work. Sure as hell don't want customers dropping by, catching me when I'm trying to relax and forget about work. I have enough of them blowing up my personal cell phone with "emergencies" at 9PM and I can't stand that...so no thanks.
