Designed to look like a human house on the outside, because why wouldn't it be, and with the inside planted like it is outside. The two windows on the left are into the "indoor" part, and as usual with the zoo's glass-fronted enclosures the reflections are appalling. The enclosure is quite deep but you can't even tell that without using your own body to shield the glass so you can see inside. The section on the right is mesh-roofed and one of the little access tunnels for the goannas is visible near the front.
