Archive research helped track down a former tenant of Lakanal House at where one of the victims of July 3rd, Catherine Hickman, died. He says a fire in the same at years earlier identified serious risks. I tracked down former architect who designed the block who argues materials used in refurbishment may have helped the spread of fire.

Research conclusion: modern materials particularly PVC windows introduced under improving homes schemes can weaken fire resistance in tower blocks.
