The pig house has been reconstructed entirely and has been enlarged as the aviary block that used to be here was demolished. A viewing area on the roof is also being built, and the doors and the stairs on the left side will be the access to that.
From what I understood based on a map published in one of the zoo's member magazines early this year the plan was to house Kirk's dik-diks at this location.
However according to the most recent information I saw at the Laafsekikkers the first exhibit has become the new home for the zoo's Yellow mongoose. It is not clear to me whether the second, larger exhibit will in fact house the Kirk's dik-diks or be for another species, or be connected to the rhinoceros and savanna paddocks.
Four Kirk's dik-diks have already arrived at Zoo Antwerpen, and they are currently housed in the former Red panda/Muntjac exhibit near the jubilee complex, but will likely not be able to live there permanently due to the ongoing renovations.
I plan to visit again later this month to view the new developments that have happened since my most recent visit, and to hopefully clear up some things also.
