Its certainly a very functional exhibit, to put it nicely, and far too small, like most of the Zoo's big cat exhibits. There is room here to expand out a bit to the sides and front, vertically upwards quite substantially, and to deck the enclsoure out much more nicely with vegetation and further items. But that doesn't seem to be particularly likely to happen.
It would suit a smaller species quite nicely, but putting more vegetation, rocks, climbing opportunities, etc., in would be the only way to make it acceptable in the 21st century.
Unfortunately I think the suggestions would only make the exhibit more appealing to the public... Space for the leopard to hide from public view would be a direct lasting benefit however unlikely to happen.
If I remember rightly along the inside barrier line of the enclosure the ground has been worn away by continuous pacing and is 1-3 inches lower than the rest of the exhibit!
