Wherever possible, I have refrained from looking at plans for the new Reptile House, so as to have my first impressions of the finished building unphased by expectations or prior knowledge. But looking at the species inventory, I seriously don't get how anybody can be disappointed by that.
Assuming that all barring the Giant Tortoise, Komodos and Congo Caecilians go on-display in the new house we can expect to get upwards of 30 species in the House, including 8 species that can be found at no other (public) British collection, and several more that can only be found at a select few. Also, please note that this stocklist is from the 1st January 2023, and across the seven months since it was recorded, and the further couple of months between now and the House's opening, it is very likely that the House will feature more species than what the stocklist suggests.
The house won't be the best on the planet, but surely it will still be the greatest in the nation and a fabulous addition to the zoo. It will provide most of the species already housed at the collection with greater homes, and offer a more thrilling viewing experience for visitors, while also incorporating new species and enhancing ZSL's focus on conservation. I'll take that over a pet shop any day...
