Just a estimate based on recent ground improvement, stand building at other clubs .what are you on about nowt to do with Bramall Lane developments £150m ???
I was referring to the previous post regarding a south stand extension and and new kop stand ( not just pillar removal) .
If the south stand was half as much as the Liverpool extension it's still £40m.. a new stand at the kop ( removal of the existing )wouldn't be far short of another £80m or so
Given inflation loss of earning etc during its probably not far off .
