I'm also in the "wash before cutting group" so I told DH that I am going to want a washer and dryer. Won't be super large but I'm not usually washing really big chunks of fabric. My current washer/dryer is great for washing large yardage (like 10 yards of extra wide) and finished quilts, and I'm bringing them with me so I'll keep using them for larger items. It will be nice to have machines for washing the smaller yardages as I buy them. I saw a decent sized front loader stackable set and something like that would work.
As to the flooring, I'm very concerned about the use of roller chairs as I will be using them in several areas. My current sewing area has hardwood flooring and I've had to put down floor protectors to keep them from getting really scuffed up. At least they are refinishable. However the good quality protectors cost $40 each, and I'd need 3-4 more of them and that would be a lot of funds to put towards nicer flooring that does not need them.
I'll probably just live with the carpet for a while, until I get something figured out. I'm starting to get overwhelmed and a bit panicky about the move!
