The left and central cages look virtually unchanged from many years ago, though I think the original 'trees' have been replaced with newer different -shaped ones. Initially there weren't even any ropes in them either, just the 'trees'.
Thanks for the info, I thought that this was a completely new house and not partly a renovation of the old one.
You don't see anything of the geigy house from the outside, because all the outdoor enclosures are on top of it or camouflage the house. Butthat will definetely be because of space restrictions, as space is something that is rather limited in Basel.
