Could the binturongs and civet be in the black lemur enclosure by the chimps?

I don't think the gibbons will be staying in that enclosure down at the bottom of the zoo very long term. I think the zoo does want to mix them with the orangs eventually (but surely new housing would need to be constructed adjacent to or within the orang house first, so why the sudden move?).
The main problem with the current gibbon house has always been its lack of height. The issue is that it sits directly in front of the grade I listed castle, so I'd be very surprised if they'd be allowed to extend it vertically. However, its height wouldn't be a problem for a terrestrial species.
If the zoo were to extend the outdoor area of the gibbon enclosure (which would be unnecessary if it were to continue holding gibbons as it's perfectly fine for gibbons as it is), I don't think the zoo would extend it to the left into the newt pools. Directly to the right of the gibbon outdoor area is one of the sea lion pools (parts of which are also listed), which is what makes me think the zoo intends to transform the gibbon enclosure into one for a semi-aquatic species such as giant otter, tapir or pygmy hippo that incorporates one of the sea lion pools. The zoo only has one older female sea lion left, who I presume will live out the rest of her days in the other sea lion pool further along.
Time will tell.
