Label #5 (Invertebrate Building) is the current Insect House, right? It wouldn't make sense for the zoo to refurbish what is already a fairly new structure.
@Buldeo I agree, it looks like the buildings are overly complicated and perhaps overwhelming the site, which itself looks a bit underwhelming. It does add clarity that the hummingbird exhibit will be reached beyond the entry portal and thus likely to be more crowded than the current exhibit's subtle entry.
