Thank you @Denise Lloyd and yes @twowheelsgood, I agree!
There are a few possible outcomes to this:
Developer Paul Tobin takes responsibility for fixing the construction (but with the time elapsed this seems unlikely)
The leaseholders have the work completed (but probably don't have the financial resources). It would be useful to know the estimated costs for this.
Nothing is done and the scaffolding remains indefinitely at taxpayers' expense. At some point this expense will exceed the cost of fixing the construction in the first place.
The structure is condemned and the apartments are rendered uninhabitable.
If the council is already resigned to the ongoing expense of maintaining scaffolding, then could a plan be made between the various parties to remedy the defects and cap the total expense?
