Option wise a hybrid between 2 & 3 would be better, all the pedestrianisation and using Parkfield avenue seems like a waste of tarmac and space.
Does the memorial park have any original covenants in place like the Rec ?.
As the whole scheme is going to cost literally millions, why compromise on a tiny 25 x 8.5m 4 lane Pool when we could fit a competition sized 25 x 13m 6 lane pool, surely an extra couple of metres would also pay off by allowing competitions and bus access for schools etc without having to escape Marple and use Grand Central.
We have the space and aren't paying for the land, I presume the original pool would be sold to a supermarket to at least fund some of these design works ?.
From a design point of view the fitness suite really should face towards the play area and towards marple bridge instead of directly at Hollins house. Not sure the sight of sweaty young fitness types would be appreciated by the seniors!.
