Thanks for the link. Looking at the plan they aren't proposing to to build a mini stadium or expand the site at all. Instead they want to extend their main building, replace some existing portacabins with proper buildings, reorganise the existing pitches to make better use of space and put in a small bank of seats for parents/spectators to watch matches on the community pitch. Nothing drastic at all really, just making better use of their existing space. Where the U23s usually play isn't even featured in the plans so definitely not getting a bigger stadium.
