Hi
I presently work in Dawson House and to be honest it really is a nice modern working environment and it will be a sad day if finally the developers get planning permission. However UU have decided that the Lingley Mere site (barely 300 yards away ) is the site to centralise everyone who works both for them and in partnership with them, and it has now become the new HQ site for United Utilities. This site is presently undergoing massive expansion both in infrastructure and the no of people employed, and already dwarfs the Dawson House site by comparison - so as far as UU are concerned, who I believe may be one of the largest employers in the North West, Warrington is the best place to be both located and to expand.
Hope this helps clear up some of the doom about the possible redevelopment of the Dawson House site.
