Mast Quay, a 23-storey tower block overlooking the River Thames, stands as a warning to rogue builders trying to evade London’s planning system.

The £36 million ($45.5 million) apartment complex situated in London’s historic military town of Woolwich was ordered to be demolished in September after dozens of planning deviations were exposed. Amongst other failings, the developers didn’t provide a roof garden, commercial floorspace or disabled access, all promised in the planning agreement.
