The postwar years also saw the rise of apartment-style housing. In the 1960s and 1970s, this kind of housing was mostly focused on low to middle income residents. Beginning in the 1950s, the city bulldozed older lower-income neighbourhoods, replacing them with housing projects, ultimately destroying large sections of Victorian housing. The earliest and most notorious example of such projects was Regent Park. It replaced a large portion of Cabbagetown with a series of low-rise and high-rise buildings that quickly became crime-ridden and even more depressed than the neighbourhood it replaced. In later years, similar projects such as Moss Park and Alexandra Park were less disastrous, but also far from successful. Canada's densest community, St. James Town, was built in this era as a high-rise community of private and public housing in separate towers, also replacing a Victorian neighbourhood. These patterns changed dramatically beginning in the 1970s and gentrification began transforming once poor neighbourhoods, such as Cabbagetown, into some of the city's most popular and expensive real estate.
