Help on enclosure

[midnightserval]

I am thinking of making a custom enclosure and was wondering if anybody could help with what size requirements i would need to hold a Black-headed python. I dont have one as yet (will have to do some major saving) but i was hoping to get all my research done and have the professional set up completed before purchasing a animal. I want to ensure it has good health and that i am well educated, i dont want to take any risks....
Any tips will be much appreciated.

im keeping mine in a click clack, when i move him up to his big one i built a 1500 x 600 x 400 (i think!)

they dont climb much at all (kinda unco at climbing) ive heard they can be cage defensive but mine is fine...
great snakes easy to keep and mine has a very nice temprement.

What is a 'click clack'? Ha Ha. I already have a few enclosures from a 4ftL by 50cmW, and a 6.5ftL by 70cmW both about 3ftH or so, i didnt measure. If they arnt suitable i will just buy another one but that will slow my saving money time right down. I also have some really small enclosures but i think they would only be suitable for a hatchie.
