It was completed in 1974, as part of the first phase of the Lancaster West Estate . The tower was named after Grenfell Road which ran to the south of the structure . The road itself was named after Field Marshal Lord Grenfell (1841--1925), a senior British Army officer . </P> <P> The concrete structure's top 20 storeys consisted of 120 flats, with a total of 200 bedrooms . Its first four storeys were nonresidential until its most recent refurbishment in 2015--2016, which converted two of them to residential use, bringing it up to 127 flats and 227 bedrooms . It also received new windows and new (albeit faulty) cladding with thermal insulation during this refurbishment . </P>
