London is increasingly becoming a city of high-rise living. There are more than 700 tower blocks, ranging from brand new luxury developments to the post-war council-owned buildings seen as a quick fix to cure problems caused by crumbling and unsanitary 19th Century hovels.
About 8% of Londoners now live in tower blocks. Some flats are bought for millions; others are relatively low-cost social housing rented from a local council at a fraction of the private rate. Grenfell Tower itself was designed in 1967, started in 1972 and finished in 1974.
Originally built as municipal housing as part of the slum clearances of the 1960s, it had 120 one- and two-bedroom flats over 20 of its 24 storeys, and was renovated in 2016.
It's in a neighbourhood ranked among the most deprived 10% in England.
Just two miles away - or four stops along the Circle/Hammersmith and City line - is 3 Merchant Square, a 21-storey tower that is part of a new development around Paddington Basin. The contemporary block was finished in 2016 and holds 60 apartments over 15 storeys.
