Obviously I don't know the full situation in this case bar the articles posted but I must admit to being very happy when the Ferrier Estate in Kidbrooke, London was demolished, with new homes and open spaces built.
It was an awful estate and many of the residents hated living there and it was an extremely volatile place to be. Words cannot genuinely describe what a bleak area this was with a haven for criminals, mixed in with vulnerable residents scared to come home every day (I knew of a boy who would come home from school and sit on the stairs in the block for a couple of hours, waiting for gangs to move from his landing. Even then, there were residents who refused to move, even though they were being offered new bigger homes not next to crack dens.
The area is still be re-built but is now a safe area to live in, work in and visit for all ages/residents including much needed facilities.
Therefore, by not knowing both sides of this story including hearing from residents happy to move, I'm open to the fact that regeneration may also be needed in this situation.
