I saw this one on Kingsnake.com the other day. They seem to have some nice big cages for burms. As opposed to the usual 8'x3'x2' cages you see. I personally have the biggest vision that they make for my big male burm. But for a big female it would not due. Check these guys out. THough most people build their own giant encloures when the snake gets over 13 feet or so.
Here is a link to a post I did about them at albinoburmese.com. I can' find the add on Kingsnake.com right now, but you can see the name of the company in the picture.
