When the HDB took over in 1960, they fully adopted the new town planning concept on a large scale, building partial towns from scratch in locations all around Singapore. Queenstown thus became the SIT's model of its version of a New Town, and they developed this further in Toa Payoh which was the first town to be built entirely from the ground up by the HDB. Initially, gigantic developments, sometimes known as Minicities, were built in areas in the city centre, Changi Point, Lim Chu Kang, Farrer Park and Seletar, and in larger areas such as in Bukit Timah and Marine Parade.
