This looks to me like an excellent development. I like the spin-off community benefits, the fact that the housing density is quite low (realise a higher density means more £££ for the developer, so there is an element of pragmatism here) and as potential brownfield site development it fits exactly with the government strategy to build more houses to take some pressure off the market where demand outstrips supply.
I note from the news article, there is the usual "we object to anything/everything" pressure group "Residents against Mobberley Sprawl" that seem to spring up whenever anyone plans anything (we've just had the same in our village which is a similar size to Mobberley), and sometimes these groups have a point when some developers push a little to hard into green belt, but here where a brownfield site is planned for redevelopment, I suggest they haven't a hope of stopping it, and rather than hiring a planning lawyer (!!) they should find better uses for any funds they have at hand!
This is really exciting for the longevity of B&W, because operating from a new building purpose-made for the present market undoubtedly brings efficiencies and opens opportunities that are restricted by the present buildings, which are less than ideal, as we saw on the tour.
All the best and good luck!
