Pretty much any of the above enclosure that incorporate water in them would be suitable.
EWD's love to climb, so giving them a bit of height is ideal (Mine enjoy climbing high and jumping into the aquarium in the bottom, so giving them a deep body of water is a good idea).
Your best bet; take ideas from any of the enclosures above, and incorporate it into the size of enclosure you are after.
This is mine i just did up tonight, all of its real and came from the backyard exept for the sand and rock at the back. Its not really pants and whatnot but still (was) living aha
