Haha I wish I even had that.  I'm stuck down in my unfinished basement where the rafters are old trees ha ha.  I have a big piece of plastic up on the rafters directly above my work area to trap the dust from falling.  I have to knock cobwebs down weekly from around my spray booth.  Anytime it rains I have water in my basement which leads to mold that I have to get rid of with the ole bleach.  Its so not a very suitable work area but its what I have and what I got to work with so I try to make it work.  Sooner or later I'm going to partition a small area and stud it up making walls all the way around it and put a real ceiling in it so I can have at least a semi sanitary work area.  I assume it wouldn't cost that much to make four small walls and a ceiling.  I may even wall up my sink and spray booth area.  At least after that's done my work areas will be able to be kept clean.  Till then, just do what I can the best I can with what I got ha ha.
