Update:
The local Council has just given Nottingham Forest planning permission to develop the City Ground to hold another 5k seats (to 35k).
The cost is... wait for it... expected to come in at £94m = almost £19k per seat!
Granted the scheme also includes a residential development, which Forest hope to to sell off to defray the stadium cost. However, they won't be allowed to sell the flats until after the stadium is complete.
