Inaugurated in 1952, the residential complex known as Minhocão took up the hillside where one of the tunnels of the Lagoa-Barra highway system now stands. That was the site of the Parque Proletário da Gávea, created by the city government under mayor Henrique Dodsworth in 1942, with 955 shacks housing 5,262 people, which by the early 1950s had become deteriorated and unsanitary. The project was grandiose and was built by the Department of Public Housing (Departamento de Habitação Popular) to meet the needs of many city hall employees, who occupied the favela areas of Lagoa and Rocinha and could no longer make use of the Parque Proletário. Five apartment blocks were planned, totaling 748 units, complete with collective urban facilities. Only one block was built, still lacking urban facilities, and it occupied part of the upper hillside.

The architect behind the Minhocão project was Affonso Reidy, who gave the block a curved design very similar to that of the Pedregulho Complex. The building built expressed the idea of a city within a building, with its corridor-streets, breaking with the residents' isolation and confronting them with the challenge of collective living. It thus replaced traditional ways of thinking about public housing with attention to aesthetics and building typology, heralding freedom and autonomy. Even with the tunnel running through it, it is possible to notice the strength of the modernist innovations in the block.
