The executive housing/affordable housing thing was only part of the problem. The main issue appeared to be that there was a material breach of the Councils Local Plan in placing a substantial exclusive housing development on Green Belt land, and an issue of sustainable transport links to the new facility. Andy is indeed wealthy, but sports facilities are notoriously unprofitable at "affordable" prices, so he and his accountants will be wary of how much of his private wealth he can commit
I'm against ANYTHING on green belt land, but from what I've been hearing, Elena Baltacha's Academy of Tennis in Ipswich is doing quite well, although a fair amount of its money is coming from donations to her Foundation. I know this is a different scenario but at least EBAT proves that it can work.
