"The apartment block was built in the early 1970s at a time when strict new building regulations had come into effect to ensure high rises would not fall down in the event of a blast or major fire. The regulations were introduced following a deadly gas explosion at the Ronan Point high-rise in East London. It marks the only time a block of flats in London has collapsed.
Emeritus professor of structural engineering at Newcastle University, Dr John Knapton, who advised insurers Lloyds of London in the wake of the Twin Towers terrorist attack, said:
“I don’t think this building will collapse because in 1968, a block of flats at Ronan Point in East London partly collapsed as a result of a gas explosion in a kitchen,”
The Telegraph reported.
“As a result of that, the design of tower blocks in the UK changed from about 1971 onwards.” From then on, the design had to allow for an explosion or a fire to remove part of the supporting structure and for the building to remain standing"
