Nacozari de García is a mining community of 12,000 inhabitants in the state of Sonora. It lacks of public and recreational spaces. The project’s intent is to design a central plaza for public use that is self sustained, providing the economical and maintenance support that a plaza requires. The plaza is conceived as a patio-like space for reflection and as a center for contemplation. It is contained by low walls made of white concrete that frame the lineal disposition of the elements that make up its interior. One of the walls functions as a waterfall - a fountain that cascades onto the canals that mark the axes where a series of ash trees rise to provide shade in the center of the plaza. At the rear the service core is found that includes a commercial space, a playground and a pergola. The proposed program allows the plaza to its daily function and own maintenance. The corner location provides alternate passages to the local people, connecting one street with the central plaza of the town. The materials used, for the Nacozari Square, combine different craftsmanship, using local manufacturers to construct the stone walls as well as the metal structures for the pergola.
