a+u’s March 2022 issue features the architecture, landscape, and cities of Colombia. A land of intoxicating natural beauty, Colombia has employed architecture as a key agent in rebuilding its cities and civil society as it recovers from decades of civil strife stemming from drug trafficking and guerrilla warfare. Situated at the northern tip of South America, the country borders the Pacific Ocean, Caribbean Sea, and the Amazon basin and is equidistant to New York and Rio de Janeiro. Photographic work by Camilo Echavarría illustrates how travels through the country cause one to feel a homogeneous, abstract passage of time. With no seasons, architecture is conditioned by various landscapes formed by the rich geographic diversity across regions. Medellín-based architect and guest editor Camilo Restrepo Ochoa takes us on a journey through his country, where architects create spaces as “types, elements, and instruments of architecture made to question limits, to build an inhabitable threshold that participates in the spatial experience of moving from outside to inside.” Changes in the way of thinking about architecture as an academic, social, and urban tool have created works “articulated through a narrow materiality and low-tech structural systems,” with “a tint of geographically driven tactile richness and a certain pragmatism.” Works by 14 architectural practices across 3 generations are presented in this issue.
