Chiviquí is a neighborhood of Tumbaco, located on the slopes of the Ilaló volcano, traditionally agricultural, it has been colonized by new settlers from the displacement of the population of Quito towards the valleys, where innumerable new constructions of single-family and multi-family housing have been implanted.

The project is placed on a corner plot, within a small subdivision of six lots bordered by a passage and the main road of the complex, which allowed the houses to be placed on the perimeter, each one on one of the streets, closing the corner with the buildings and allowing independent access to each of them through the roads.

The proposal starts from the need to make two twin houses for two brothers. The program was extensive and the lot was small, so it was proposed to create common areas that could be shared among users, optimizing land use.

The parking lots and service spaces were placed in an underground, taking advantage of the natural slope to facilitate access, from the basement the houses can be accessed directly by two independent circulation cores, which later become the vertical circulations of each of houses. They also share gardens recreational areas such as swimming pool and hydromassage that are in the patio that embrace the buildings.

The houses have similar areas, but they are not the same; three bedrooms, each one with its bathroom and dressing room, TV room, a study that leads to a double height and a large social area that contains in a single space, the living room, dining room and open kitchen, all these areas lead to a large exterior porch covered by the same volumes of the upper floor.

The construction system is a foundation and  retaining walls of reinforced concrete with columns and steel beams, slabs on collaborative plate.

The architectural response aims to be consistent with the place.  The scale of the building is respectful of the neighbors,  the corner is marked with a three-meter overhang, the implementation of the volumes is parallel to the urban fabric, which allows large front gardens towards the streets, keeping the vegetation as the protagonist, in keeping with the landscape of the valleys of Quito.
