The Siamese Towers are likely the most famous work of Alejandro Aravena, a Chilean architect who is the executive director of the Elemental S.A. firm and recipient of the Pritsker Architecture Prize in 2016, an award given to living architects for demonstrating “a combination of those qualities of talent, vision, and commitment, which has produced consistent and significant contributions to humanity and the built environment through the art of architecture.” The Siamese Towers are actually one structure, with the top split into two parts that lean away from each other, while sharing the same lower part, akin to Siamese twins. The Towers were built by Aravena and his team for the Pontifical Catholic University of Chile in Santiago (Aravena’s alma mater); more specifically, these towers were to hold the Center for Technological Innovation. Because of this, the university wanted the building to more or less scream innovation. The university specified that the building be built with a façade full of glass, to meet this need. Aravena and his team built the tower(s) in its unique shape to further enhance the high-tech look of it. The towers also have a double skin of glass, with a layer of air in between for thermal insulation. As the building is supposed to be used as a technology center, most of the interior rooms actually don’t face the exterior glass walls, in order to keep them dark.
