The orangs moved to a whole new building (the OANG.erie) in 2009 with a brand new and quite high standard exhibit. The old Monkey House (as seen in this picture) was undergoing massive renovations during my visit in 2011. I don't know how it looks now but judging by Vienna's normal standards my guess would be that it looks pretty good.
I didn't realise until I was looking at the current map for the panda thread that the ORANG.erie is outside the previous zoo boundary. Looking forward to seeing the new set-up - hopefully later this year.
