Passage: Both low-cost and luxury housing were built by the government in the Brasilia. The residential zones of the inner city are arranged into superquadras ("superblocks"): groups of apartment buildings along with a prescribed number and type of schools, retail stores, and open spaces. At the northern end of Lake Paranoa, separated from the inner city, is a peninsula with many fashionable homes, and a similar city exists on the southern lakeshore. Originally the city planners envisioned extensive public areas along the shores of the artificial lake, but during early development private clubs, hotels, and upscale residences and restaurants gained footholds around the water. Set well apart from the city are satellite cities, including Gama, Ceilandia, Taguatinga, Nucleo Bandeirante, Sobradinho, and Planaltina. These cities, with the exception of Gama and Sobradinho were not planned.
What type of private clubs were built by the Brasilian government?
