The building is located in the Santo Domingo Savio neighborhood, on the northeastern slope of Medellín. The lack of public investment and the weak presence of the government in this territory increased during years the inequality in one of the poorest and most violent areas of the city. The School stems from the project “Medellín, the most educated” which aimed to improve the quality of basic education in the neighborhoods with the lowest coverage. The Mayor Sergio Fajardo proposed to refurbish 132 educational institutions and to build 10 new schools creating at the same time new spaces for the encounter of communities. The site for the AD-SDS School was located between two existing schools; the new building should link both and wave them to the urban structure using the concept of “open facility”. Through the conception of an open architectural and urban intervention the new School should become a center of cultural, recreational and educational activities; an urban reference that promotes the integration of the society. The lot had 140.000-sq. feet, an irregular form and a 35% slope. These factors made the project more complex but offered an exceptional condition; the building could work as natural lookout to observe the city and its mountains. Besides, it was a drop of about 3.5 meters between the access road and the site and the lot served as connection between neighborhoods, it was crossed by some paths that linked the irregular urban structure; the project had to dialogue with these signs. ​
