Rio de Janeiro’s urbanization developed in two directions. The prosperous neighborhoods along the beaches and in the center followed the rails of the tram lines, while the peripheral zones of the working classes to the north emerged along the railroads. Public facilities, such as libraries and parks, were continuously planned in the city center. The public voids left in the peripheries were filled up by private institutions such as shopping malls. Green space is scarce in the vast outskirts. A space that has remained open is the network of transmission lines. It reaches many residents in the dense peripheries in the north zone, but the space is currently inaccessible. The space can be transformed into a linear park, equipped with public facilities. Public interventions, such as plazas and sports fields are planned on the strip. Vacant spaces along the strip are used for buildings, in particular with public functions. In this project I proposed a design for a building with several public functions: a library, an auditorium, and a bus station. In the commercial heart of Madureira, an area dominated by commercial activities, the building will be a haven of public space that surpasses the interest of the neighborhood. Through connectivity, function and size, the building will be significant for the entire periphery of the city.
