I was also looking into building an outdoor enclosure so Pablo could get some natural sunlight. I ended up buying a 65 gallon reptarium from LLL reptile and it works perfectly!! It was only 30 bucks, its great in size, and works great for outdoors. it also folds up, so when I'm not using it I just fold it up and put it in a closet. I plan on buying a few cinder blocks (VERY cheap anywhere), and a piece of plywood to make a "table" to set it on outside. We don't treat our yards due to the dogs, but I know my neighbors, etc do and want to raise his cage off the grass just to be on the safe side. Good luck if you end up building one, but for me the reptarium worked out better.. and was a GREAT price. It's also good bc here in good ol' Missouri we get harsh winters, and I don't think an outdoor cage would withstand that very well, and we don't have room in our garage for the size of enclosure I planned on building. It's also helpful to have the reptarium that I can store in the closet all winter, that way I have a spare tank if ever needed. Just my two cents! Let us know how it goes!
