lool I like the ideal of an attic for my reptile room ( my grandmother's one runs the entire lenght of the house as one large bedroom.I just dread the ideal of the steps for cage movement lol. I don't have any worries cause I know she not let me have them in there lol.

I alway plan on if i get a place with a car garage I simple enclose it and make a larger reptile room/building out of it. with a raised floor a restroom, and a office/qt room all with heat/air so I can more less live there. I would also knock out a window( or the door depending were it was placed to make it just a addition to the house.) I would later build a garage to keep he mower and such items in if ther was room.

otherwise I just simple build a large building out to house it all and make custom racks/ cages on the side for anyone I sold to locally lol..
