I hadn't seen that, interesting but the site is suggested only IF it is believed an existing site in unavailable. My solution is to utilise the existing buildings if it is attractive to the commercial organisations. I see this as a solution as m&co get a cheaper rent, coop don't have an empty building, newco supermarket get a new store in a good location, MIA fend off Hibbert la & Marple get the supermarket they demand
Just a couple of possible problems there Duke.
M&Co may not want to move to smaller premises.
The Co-op used to be in the building where M&Co currently is, but then it had the whole ground floor, including what is now Superdrug. This wasn't large enough so they had the current store built. This may mean that the Co-op are the landlord there, and therefore wouldn't rent to a supermarket, even though it would only be convenience store size.
Also, I doubt that any new supermarket of a viable size, i.e. if they also got the Superdrug premises, would accept a site without car parking right alongside it.
