The houses, located in the form of L around the patio, I have inscribed within a grid of 9x3, have been projected as equitable as possible, thus leaving aside any possibility of social disagreement. This means that the two houses, in their delivery stage, are developed in two floors, with the same amount of square meters (54m2), the same amount of rooms (3) and common places, the same square meters of extension, (9 m2 in the second floors) and have the wet rooms in the same vertical core. Their differences are given in their spatial distribution and their location in relation to the volume of three floors.

The grouping that is projected (72 houses), favors that all the houses share two of their four walls with adjacent neighbors, this helps to diminish the energy demand of the enclosures, developing this way a necessary sustainable economy for this type of housing.

Assuming the costs of production, in relation to the material and construction of the economic housing, the project proposes to accompany the masonry, of a system of semi-prefabricated production, since this one makes possible the introduction of new constructive systems, major rapidity of execution, major accuracy (more precise dimensioning), better economic control (there does not exist waste of material), improvement of the quality, as well as of the control and flexibility in his facilities. The semi-prefabricated system will be used to build ribbed concrete slabs, consisting of ceramic beams and vaults, plus a concrete slab poured on site, reinforced with an electro-welded steel mesh.

In relation to the choice of the location where the project is located, we have decided on both the impact of the earthquake in the area, as well as its heritage status, the center of the city of Talca. Given the fact that in the centre of this city 39% of the population corresponded to socioeconomic strata D and E before the earthquake, we believe that the development of an economic housing management model for Talca, thought within the framework of the Solidarity Fund I Housing Projects, can be an alternative for families to stay where they lived before and thus maintain their central location and social networks.

Specifying the location within Talca, we have chosen Sector Eight of the city (Santa Ana) where 75% of the houses (393 houses) are damaged, of which 36.5% (191 houses) are to be demolished and 38.6% (202 houses) are under repair. Within this sector we have selected the block perimetered by streets 8 north, 7 north, 10 east and 11 east, as it presents demolitions towards three of the streets. This has caused these three streets to be connected today inside the block, thus reinforcing the idea of a central space for social relations, but this time at an urban level.

To conclude, we believe that it is necessary to equalize the variables involved in economic housing, under the logic of a community society. This look only rescues a real current condition, which if it is managed to be articulated would propitiate a sustainable urban dynamic. The operation that the project produces to achieve this articulation, is of the hand of the idea of the patio as space of action, as much at the scale of the housing as of the city.
