£74m included fit out. The additional costs tagged onto a lot of stadium projects are not always stadium connected (to add value or attract investment eg. £400m for Kirkby for instance, when the stadium component was only £100m). I haven't seen the breakdown for LFC but these could include the club museum, external facilities such as the massive club shop, site preps for a Hotel and all associated infrastructure, land/property acquisition..... much of which that might not apply to adding a net 6-10k to the Bullens, and another 6-8k to the park end and/or replacing/expanding the upper Gwladys St to achieve 52-60k as illustrated in the pdf, which also cited other stadium redevelopments that were much cheaper per seat than LFCs mainstand, which after all is practically as big as Wembley's stands. Costs do not rise if you negotiate fixed contracts and avoid imponderables like heritage demands, rising sea-levels (which between them have already added £100m+ already and or any additional infrastructure costs (we've already been told that Merseyrail will not be footing the bill for a new station in Vauxhall, how much will new marshalling facilities or platform extension be at Sandhills?), and anything else that a new site might generate.
Yes, BMD could project other opportunities, but the design hardly appears to exploit these. No closing roof for concerts (and to stop the front 15 rows getting soaked as occurs at so many stadia with high roof lines)? No moving pitch to facilitate year round multi-purpose operation? Just 20 boxes when some clubs have over 100, with some convertible to hotel/conference suites? This stadium is costing over double Lille's which was structurally more complex and provided all of these. It was complete only 7yrs ago. Sumilarly Feyenoord's new proposals due to open roughly at the same time, but is over 10k larger with a closing roof? So yes, opportunities and appearances are there, but what is the reality and what is the cost, and can we all get there as easily as GP which might cost only 25% as much for a similar capacity? How much of an increased opportunity might that represent in being able to building a good team too?
