I agree with Crowthorne and sooty. London Zoo's history is its USP. That shouldn't mean turning it into a mausoleum.
A very senior London Zoo figure told me that the state of the Mappin Terraces' decay had been exaggerated. Granted this was twenty years ago, but I am inclined to scepticism on the subject. What certainly is a problem is the Aquarium. Opened in 1924, it is now, after heroic efforts on the part of its staff, able to use about 60% of its available exhibit space. I have to say that personally I think that there comes a point where you decide that you are throwing good money after bad.
If some of the office buildings on the Outer Circle - now approaching sixty years old, which is prehistoric in IT usage terms - could be put to other uses, ZSL would be far better off. In the long run, the Institute would surely be better sited at Whipsnade. Think of Bletchley Park, barely twenty minutes' drive from Whipsnade . It was chosen as the base for the Second World War Enigma code-breakers as being equidistant from London, Oxford and Cambridge, a fair comparison with the needs of the Institute.
I know I am thinking in very "blue sky" terms, but the main office block is the perfect place for an Aquarium within the ZSL sites. It could stay open when the Zoo itself closed, perfect both for visitors on dark winter evenings and evening functions at any time of the year. The present Aquarium could hold invertebrates, freeing up BUGS to retain its interpretative material on the role of ZSL and the zoo world generally, whilst holding rotating displays of art from within ZSL's own collection and elsewhere.
The Casson Pavilion could so easily be holding (say) Lowland Anoa and Visayan Warty Pigs on the rhino side, both conservation dependent species with viable EEP populations. The interior dens, currently holding mostly events animals, could so easily be holding a
Calliosciurus squirrel, tree shrews, chevrotains or loris. The building itself could be a major showpiece, and the centre of a tropical Asian display, which could highlight ZSL's origins; bring Raffles' bust back into the heart of the Zoo, where it sat until the old Lion House came down in 1975!
And the Round House could be themed around New Zealand fauna. Kea on the outside, kiwi and Boobook Owl inside. That Meerkat display could so easily be glassed over and used for tuatara.
The Penguin Pool apart, all of the listed buildings could be put to use. Some might need more money than others, but the main requirement is imagination.
