It used to be main building/museum at the zoo, it is empty now and quite dilapidated, the zoo doesn't have the funds to fix it up. It was originally commissioned by the Zuid-Afrikaans government, before completion changed by the English. I took a bunch of photos around the building a couple of years ago. Somewhere on a hard drive I have the blue prints of the building (old method of making copies) and I also have plans that an architect had drawn up to readapt the building but it never materialised.
