As said, main building is listed not the elephant. This could be part of the problem - if upkeep costs of the main structure are the issue then no-one really wins. But if it were the case I think the listing could be removed. If anything you could get any replacement building to have a FoB element of even possibly incorporate the existing part (which I believe is the reason for the listing more than the building as a whole).
I think the point of a city centre venue if trying to get people from farther afield would be to get people into and through the city centre so businesses benefit and enable growth - at the Friargate area people get off the train, go to the gig and then get on the train back home. And I think given how they've now started to construct it the available spaces wouldn't be very conducive to it. Locals would be more likely to go by bus if going by public transport, and although that would take them past Broadgate etc they're much less likely to be spending money on restaurants etc if they're travelling by bus.
Besides, anywhere within the city centre would be as close as New St is to the arena in Brindley Place (which I use as my template for such a plan) and as long as you get the acts people will do that little bit of a journey if they're willing to get on a train into Cov. I'd love a similar waterside placement around the canal basin but I think it'd have to be at least as far as Broadgate - restaurant quarter and large space for meeting up. As I can't see the Primark building going any time soon I guess the other option would be the space between Ironmonger Row, Burges and Trinity St with a space between it and the Palmer Lane development enabling more of the river to be uncovered.
Ive probably mentioned this before so apologies for labouring the issue, but which part of the sports centre is listed? Do any of you guys know?
Also, the council have commented that the costs of keeping the swimming baths open are astronomical. I wonder if that is down to the cost of the pool or if the building itself is beyond serviceable - I seem to remember a while back that the maintenance of the roof itself was proving to be prohibitive (that may be down to the fact it is suspended over half a million gallons of water, though). Regarding a live music venue or civic centre, I cant help thinking it would be better supported if it were situated nearer the railway station, there just isnt the land available. Who knows, maybe the plans for CCS could be altered? Its not like theyre ploughing ahead with things.
