I largely agree, I think I just specifically excuse the penguin pool from that just on how charismatic and famous it is as a piece of history and how, in my opinion at least, it would be impossible to provide a sufficient exhibit with it nowadays. But I certainly feel that way about much of the rest of the zoo - one of London's greatest strengths is of course its history, but as many of us have repeated far too many times on here sections such as the Mappins are massively holding back huge sections of a rather small zoo. Some of the rather questionable choices made in the past 10-15 years - the loss of the giant anteater exhibit to be turned into entirely dead space sticks out the most to me, as well as the North Bank - did a lot to further reduce the used space of the zoo, but equally I do think they've done a very good job of squeezing a lot of new developments and interesting species into far less space than they have any right to manage. When they are actually allowed to work their magic, the planners at London are to me second to none.
That said - the new developments coming in the next few months I've heard whispers of are very exciting, but I haven't got a clue how they're going to fit them all in. I'm hoping that it will finally mean utilising some of that unused space, potentially even the North Bank - but I can't share any more publically, nor do I have much more to share!
As an aside, I fell down a bit of a rabbit hole of old ZSL threads on here earlier today and it's genuinely lovely to read how in all honestly they completely beat the odds over the past few years, as well as people's expectations. I'd entirely forgotten that ZSL had at least a £5 million deficit in 2019, followed of course by the pandemic, and in 5 rather short years they have a net profit of several million on top of several more in "savings". I think public opinion has also done a bit of a U-turn as well, as though the zoo has always been fairly well received there was a point not too long ago where complaints of tired, empty or generally dull exhibits were becoming more common. They seem to have all but disappeared, and I think a few of the "gambles" ZSL have taken - Monkey Valley, the reduced-sized reptile house, moving the tortoises etc - have paid off and then some in the eyes of both visitors and fanatics
