Much of the Hyde Park estate fell into deprivation in the 1980s following the collapse of the local steel and coal industries and subsequent economic downturn and population flight from Sheffield. Blocks C and D were refurbished in 1990 in order to be used as the athletes village for the 1991 World Student Games, hosted by Sheffield. Following the conclusion of the games, they returned to use as council housing. The smallest and largest of the Hyde Park blocks, A and B respectively, were both demolished in 1992; they had not seen use during the games. Blocks C and D were subsequently leased out by the council to Places for People and refurbished in a similar manner to the Herdings Twin Towers in the late 1990s, receiving new names in the process – "Harold Lambert Court" for Block C and "Castle Court" for Block D. Both blocks were refurbished with predominantly white cladding covering their distinctive concrete structures, with red detailing on Castle Court and green detailing on Harold Lambert Court. The land formerly occupied by Blocks A and B was redeveloped as the Manor Oaks Gardens low-rise detached housing estate in the early 2000s.
