Entrequadras in Brasilia’s Pilot Plan

In 1957, the national competition for the Plano Piloto of Brasília — the urban plan for Brazil’s new capital — was won by Lucio Costa. In his proposal, the residential sector was structured around the superquadras, or residential superblocks, combined with local commerce, open areas, and shared public facilities. Between these superblocks, Costa planned strips of land intended for public and community facilities, although he did not yet name them as entrequadras (interblock areas). These spaces were part of a broader urban structure, informed by references such as the Garden City, the Neighborhood Unit, and modern urban planning debates on open spaces, collective housing, circulation, and facilities for everyday life. In the original proposal, the superquadras were not meant to function as isolated units, but rather as parts of residential groupings connected by local services, open spaces, and shared facilities. In this context, the areas later known as entrequadras would play an important role in mediating between the residential scale and collective urban life, accommodating uses such as schools, churches, cinemas, neighborhood clubs, and other community facilities. Despite this conception, their implementation was uneven: only the 107/307/108/308 Neighborhood Area came closer to the initially proposed model, while many of these areas remained unbuilt, received unexecuted projects, or had their uses modified over time. Through the survey and analysis of urban plans for these areas, as well as complementary projects, legislative changes, on-site visits, and secondary sources, this study seeks to trace and understand the transformations of the entrequadras from their formulation in the plan to their materialization and appropriation in the built city.
