Guess work and Chinese whispers??? I don't think that's fair. As nothing has been published yet , then there has to be a certain amount of deduction made. ( a preferable word to guesswork ) What has been published in various formats , some now withdrawn , is the intention of the college to sell to fund building elsewhere. This was all sufficient for the complete set of local councillors and the MBC planning officer to attend a meeting about it all. Not a Chinese whisper in my view, but something rather more concrete.
As regards the size of any potential supermarket, there have been two posts made which include visual comparisons of the Hibbert Lane site with the Tesco site in Stockport. These are to scale and give an indication of what could be done. No supermarket is going to pay £12 million for a site and build a convenience/express type shop on it. Regardless of the cost, it would be in the wrong position. Any Tesco Metro type store would be certainly located in the centre of Marple.
