Infonavit has selected Tatiana Bilbao's studio to be part of the architectural firms that develop a proposal for the Urban Redensification project. The exercise is a small building with departments of social interest for colonies with high population growth rates.Located in the Town of Apodaca, Nuevo Leon, this project contains 5 elements, of which three are houses and the other two are commercial space and private community services. These spaces are distributed along four floors and a roof, which is the service area, and has a terrace open for all users.Each one of the houses has a unique size, to cover the needs of different types of families and economic budgets. The commercial premises have an independent access to the houses, so that families have privacy in their homes.Given the condition of building between dividing walls and its width limited to five meters, the free space is concentrated on the back side of the building, where each department decreases its footage to generate a terraced profile with greater openness to its own green lung: an area social, which works as an extension of the living and dining spaces, but at the same time moving away from the street, to maintain that outer space as private.The building is developed in a total of five floors. The ground floor has a commercial space of 4 meters in front and in the back two rooms. It Also has the courtyard of Department 1. On the first floor is the rest of Department 1, which has a total of three bedrooms and two bathrooms, and a room that is developed as an area of study. The Second Floor is covered in its entirety by Department 2, with two bedrooms and a bathroom. On the third floor is the most adjusted apartment, which, despite its square meters, also has a balcony to the rear area of the building, two bedrooms and a bathroom.
