Chimp Lookout:Above the Agamid Lizard/Spiny Turtle house

This looks better than the previous outdoor enclosure, have they extended it much or just removed most of the fake rock?

The last time prior to this that I visited,the chimp house was under renovation.And it was 8 years prior to that that I paid my last visit.Most of the extension has been inside,with the use of fake rocks,but i'm not sure what the old exterior chimp enclosure looked like
