Your biggest concern is your cool basement. You might consider a thick wood for your cage as it will be easier to retain heat inside the cage. Make sure it is VERY secure (thick, tempered glass fronts, reinforced seams, heavy brackets/locks, etc.). I would recommend not exceeding a cage over 2' in height so you can adequately heat the cage (as the other post mentioned, a 8' x 4' would be quite adequate for the largest of burms). I use Pro Product radiant heat panels exclusively and absolutely love these products....this would work well for your situation. Aside from that, you might also include a couple of fluorescent lights if the cage is kept in a dark basement...just connect them to a household timer but leave the heat on 24 hours a day. Humidity can be accomplished via daily misting or, more preferably, the inclusion of a misting system. GOod luck and post a pic of the cage.
