British Prime Minister Theresa May has ordered a full public inquiry into the inferno that swept through the public housing block within an hour Wednesday morning.
While investigations into the cause and progress of the fire have yet to begin, questions are being asked about the nature of cladding used to improve the thermal insulation value and appearance of the building.
The fire was finally put out this morning and now, images have started to emerge showing the dark black mess left behind in a building that was once the home of plush London apartments.
She said "a good half" of the building had yet to be searched in detail, adding: "It is the upper floors which will be more challenging and will need some additional shoring up for us to be able to get in there".
Some residents said the official advice was that people should stay inside in the event of a fire.
Firefighters first responded to reports of a fire at the 24-story Grenfell Tower building early Wednesday local time, the BBC reported.
Survivors said they saw the flames racing up the exterior of the building, which had recently been covered in cladding during a major refurbishment finished past year.
Southwark's deputy leader Stephanie Cryan, who is cabinet member for housing, said that the "terrible news" of the Grenfell Tower fire was "particularly raw for us in Southwark, bringing back awful memories of the Lakanal fire".
Emergency services said it was too early to say what had caused the disaster.
"Hundreds of thousands of people in our country live in tower blocks, very high-rise tower blocks". Celebrity chef Jamie Oliver has offered free food for survivors at one of his nearby eateries. "Sadly this figure is likely to rise, and my thoughts and prayers remain with all those affected", he said.
It is believed virtually all the residents in the top three floors of Grenfell Tower in North Kensington, West London, perished in the devastating fire, which burned at over 1,800F.
Survivors, many of whom lost all their belongings in the blaze, spent the night at emergency shelters, as charities and local support groups were flooded with donations of clothes and bedding from shocked Londoners.
