Apparently planning expires in January, August is the date they expect to need to start that would mean they wouldn't need to reapply.
That isn't to say they couldn't throw more resource at the project to bring it back in scope before January.
Reality is, without someone to buy the Mem, they need to source funding. Could be the family are happy to invest, could be they have funding from elsewhere. Either way, it is a gap of plus ten million.
