A lot of these new housing developments are merely replacing housing that`s disappeared from Blackburn. Take a look at the Moseley St area of B/burn, a few hundred terraced houses have been flattened in the last 2 years. The area near the firestation in B/burn had 4 entire streets pulled down in the early 80s & haven`t been replaced. A large chunk of Darwen (behind Sainsbury) is due to be flattened. Anybody remember the lower Audley area? 100s of terraced pulled down....granted, new housing has gone back up , but only a fraction of the amount originally there.
Lots of new housing is going up, but plenty have gone aswell.
