Juan Viejo said (with my emphasis added):
I last heard that the court had ruled against the city (or the city just dropped the case), and now the KH and assembly hall were going to be built on the property.
So, the branch expects a congregation to subsidize an assembly hall as well as build their own hall? That explains the higher price, and also the three-times-bigger parking lot that another poster mentioned. If true, it seems to me that the local members are getting a very bad deal.
