Imagine being told to move out at any time, nightmare stuff, and it does seem all a bit unnecessary to me, this stuff has been on these flats for 10 years without significant incident, it could be done far better than this, that's for sure.
One thing that has to be looked at, is the housing of old and disabled people in these blocks, not to mention young families. If another fire occurs, getting elderly, disabled and young kids, from high up floors is a logistical nightmare, as they can't use lifts, and can't move quickly. They should only be on the lowest floors only in future, and ideally not in these buildings at all, that will be another difficult logistical problem.
