Weird Non-Exhibit Area

That stone house is part of what was a Bennett's Wallaby/Emu yard, which looked like this back in 2011:

However, there is a second stone house in the left-hand corner (on the photo link) and the fencing is different in the background. Is the zoo perhaps building a brand-new exhibit of some kind?

There is what appears to be a wallaby in front of the back stone house, apparently the exhibit is being divided?

The stone house in the foreground is part of the Bennett's Wallaby/Emu exhibit; the fence coming off it is the divider for that enclosure. Maybe in the past the exhibit extended into the area in this photo, but it doesn't now.
