The 1950s and 1960s saw the construction of numerous brutalist apartment blocks in Sheffield, England. The Sheffield City Council had been clearing inner-city residential slums since the early 1900s.[1] Prior to the 1950s these slums were replaced with low-rise council housing, mostly constructed in new estates on the edge of the city.[1] By the mid-1950s the establishment of a green belt had led to a shortage of available land on the edges of the city, whilst the government increased subsidies for the construction of high-rise apartment towers on former slum land, so the council began to construct high-rise inner city estates, adopting modernist designs and industrialised construction techniques,[1] culminating in the construction of the award-winning Gleadless Valley and Park Hill estates.[2]
