Morocco In the French colonial period, the entire city of Marrakesh - the city inside the defensive walls - was razed and redeveloped, except for the preservation of mosques, madrassas, and funerary memorials. The preserved madrassas include buildings erected as caravanserai. Singapore The history of Singapore's urban renewal goes back to the time period surrounding the Second World War. Before the war, Singapore's housing environment had already been a problem. The tension of both infrastructure and housing conditions were worsened by the rapidly increasing number of the Singapore population in the 1930s. As a consequence of the war and the lack of economic development, between the 1940s to the 1950s, the previous evil of housing conditions continued to happen. As much as 240,000 squatters were placed in Singapore during the 1950s. It was caused by the movement of migrants, especially from peninsular Malaysia and the baby boom. In mid 1959, overcrowded slums were inhabited by a big number of squatter populations, whereas these areas lacked the existence of service facilities such as sanitation.

However, due to the lack of urban planning experts caused by the deficiency of professional staff, criticism came from many urban practitioners. The professional team recommended by the United Nations then was asked by the government to cope with the urban renewal matters and its redevelopment plan in 1961. Based on the UN assistance report, two pilot developments were initiated in the end of 1964 by the government. These redevelopments then led to the success of Singapore's urban renewal because the government could provide sufficient amount of public housing and business areas.

The obstacles came from the resistance of people who used to live in the slums and squatters. It was reported by Singapore newspapers that those people were reluctant to be replaced. This became the major problems of 1960s redevelopment schemes. Affordable land value also became one of its reasons. Another problem was that the government had to purchase the private land owned by the middle and upper society to make the land vacant and be
