a Male sand boa would do well in a 24' x 24' x 24' enclosure or do ya think he'd feel cramped in there?

I am having some custom enclosures built soon, probably from animal plastic or monstercages, RTB will be in a 8' x 24" x 24", and plan on stacking two 4' x 24" x 24" on top for the balls, then i'd like to also get four 24" x 24" x 24" to stack on top of those for some smaller types, trying to think of what interests me and will fit in that size. (I am going 8' x 24" x 24" for the RTB because I have a baby male green anaconda coming soon and thats the size footprint i plan on for him until I need a bigger enclosure for him, though his will be a more custom build and be 30" tall.)
