I agree with SMR that 10 years is an absolutely unrealistic lifetime for a multi million pound building. But after that sort of period it is quite realistic to look to repair and upgrade individual exhibits. It has been done with the jaguar house at Chester, so I would be surprised if something similar will not happen to RotRA when the opportunity arises (after all orangs are much more destructive than jaguars). The open air enclosures probably won't need much attention, provided the vertical poles are structurally sound. But the indoor enclosures may need new floors and I would like to see some of those swaypoles. I wonder whether it will be worth replanting one of the wired outdoor enclosures.
To respond to Pertinax's point, the fact that the Zoo wishes to build new accommodation for Sumatran orangs shows their commitment to working with this species and to improving conditions for the Borneans as they are proud of their work with both species.
