The redevelopment of the shed end is a long term project that will require massive investment.
Plans have already been drawn up for a stand that is something like 1500 if I can remember correctly.
Also talk of rooms for catering, hospitalty stuff, bars, and all that stuff.
Anyway from my understanding the shed end redevlopment is still a while away until substantial funds can be collected for it.
Its more of a medium to long term goal from what I could gather.
