Grenfell Tower is a derelict 24-storey residential tower block in North Kensington in London, England, the remains of which are still standing following a severe fire in June 2017. The tower was completed in 1974 as part of the first phase of the Lancaster West Estate.[1] The tower was named after Grenfell Road, which ran to the south of the building; the road itself was named after Field Marshal Lord Grenfell, a senior British Army officer.[2]

The building’s top 20 storeys consisted of 120 flats, with six per floor – two flats with one bedroom each and four flats with two bedrooms each – with a total of 200 bedrooms. Its first four storeys were non-residential until its most recent refurbishment, from 2015 to 2016, when two of them were converted to residential use, bringing it up to 127 flats and 227 bedrooms; six of the new flats had four bedrooms each and one flat had three bedrooms. It also received new windows and new cladding with thermal insulation during this refurbishment.[3]

Prior to a fire, which began in the early hours of 14 June 2017, the Royal Borough of Kensington and Chelsea and central UK government bodies “knew, or ought to have known”, that their management of the tower was breaching the rights to life, and to adequate housing, of the tower’s residents, according to a later enquiry by the government’s own equalities watchdog.[4] The fire gutted the building and killed 72 people, including a stillbirth.[5] In early 2018, it was announced that, following demolition of the tower, the site will likely become a memorial to those killed in the fire.[6]

The 24-storey tower block was designed in 1967 in the Brutalist style of the era by Clifford Wearden and Associates, with the Kensington and Chelsea London Borough Council approving its construction in 1970, as part of phase one of the Lancaster West redevelopment project.[7][8]

The 67.3 m (221 ft) tall building contained 120 one- and two-bedroom flats (six dwellings per floor on twenty of the twenty-four storeys with the bottom four, the podium, being used for non-residential purposes). The floors were named ground, mezzanine, walkway and walkway+1, floor 1, floor 2 etc.[3] It housed up to 600 people.[9]

The tower was built to the Parker Morris standards. Each floor was 22 m square, giving an approximate usable area of 476 square metres (5,120 sq ft). The layout of each floor was designed to be flexible as none of the partition walls were structural. The residential floors contained a two bedroom flat at each corner, in between which on the east and the west face was a one bedroomed flat. The core contained a stair column and the lift and service shafts.[10] One-bedroom flats were 51.4 m2 (553 sq ft) in area and two-bedroom flats were 75.5 m2 (813 sq ft).[9]

The building was innovative, as most LCC tower blocks used traditional brick work for infill whereas here precast insulated concrete blocks were used, giving the walls an unusual texture. The ten exterior concrete columns were also unusual.[11] In addition, other tower blocks of this era had four flats per storey, rather than six.[10]

The original lead architect for the building, Nigel Whitbread, said in 2016 in an interview with Constantine Gras, which was later partially repeated in The Guardian,[12] that the tower had been designed with attention to strength, following the Ronan Point collapse of 1968, “and from what I can see could last another 100 years.” He described it as a “very simple and straightforward concept. You have a central core containing the lift, staircase and the vertical risers for the services and then you have external perimeter columns. The services are connected to the central boiler and pump which powered the whole development and this is located in the basement of the tower block. This basement is approximately four metres deep and in addition has two metres of concrete at its base. This foundation holds up the tower block and in situ concrete columns and slabs and pre-cast beams all tie the building together”.[10]
