More than four years after a fired raged through the 24-floor Grenfell Tower apartment building in London, causing 72 deaths, the government has told builders and developers they must fund and replace non-compliant cladding on buildings that are 11 to 18 meters tall—at an estimated cost of $5.5 billion.
By March, the industry must develop a plan to replace cladding on medium-rise buildings of the type that caused the Grenfell inferno or face government mandates. Taller buildings are covered by another government plan.
