Just acquired a Juvenile Beardy - his setup

[Germ]

4 feet high would be pointless, hard to heat & provide adequate UVB, also would provide dangerous fall distances for larger, heavier BDs. While they will climb around when younger, older BDs, adults are much less active, don't climb much other than to bask. BDs are a terrestrial, semi arboreal (to get above to bask) species, adults are quite lazy, by our standards. Tall enclosures over 24" high are really not recommended. What may appear 'Awesome' to you, may not be practical or safe for them ...
