started to return and in the 21st century most of the concrete tower blocks have been demolished. Glasgow Corporation's replacement of old, outdated and crowded housing with new high-rise towers of social housing in the 1960s greatly improved conditions but had social consequences. Lack of awareness of the effects of concentrating families resulted in poor design, and the low-quality construction of the concrete, 20-storey flats led to innumerable social and health problems among the residents. Many of the blocks developed mould and structural problems. Their designs prevented residents from visually controlling their internal and external spaces, adding to issues of social dysfunction. The Queen Elizabeth Square flats, designed by Sir Basil Spence, were demolished in 1993 to make way for a new generation of housing development. In 2004, Glasgow Housing Association announced plans to demolish more of the decaying high-rise blocks, and to comprehensively refurbish and re-clad others. Two of the Area D blocks (Caledonia Road), as well as the entire Area E (Sandiefield) and Laurieston (Stirlingfauld / Norfolk Court) high-rise estates, were demolished between 2002 and 2016. In 2021, it was announced that the two remaining Area D multi storey blocks would also be condemned, meaning that the Area B or "Riverside" estate, designed by Robert Matthew, will be the only high-rise flats left in the Gorbals. New housing has been developed at lower density, with design elements to encourage residents' and public safety. Much of the area, particularly Hutchesontown, was comprehensively redeveloped for a third time, providing a mix of private (market rate) and social housing. Earlier phases of this recent redevelopment tended toward yellow-brick reinterpretations of traditional tenements, in a post-modern style. More recent phases, masterplanned by Piers Gough, have employed noted modern architects such as Page/Park, Elder & Cannon and CZWG, resulting in more bold and radical designs, accompanied by innovative street plans and high-quality landscaping. They incorporated many pieces of public art. The Gorbals Leisure Centre opened in January 2000, and the number of shopping facilities in the area is on the rise. In 2005, fire destroyed the Catholic Church of Blessed John Duns Scotus as a result of a fallen candle. The church was restored and reopened for worship in September 2010. With much of the Hutchesontown area of the Gorbals improved, the urban and social-regeneration program expanded into the neighbouring Laurieston area to the west.
