Plan:b arquitectos

PLAN:B Arquitectos is a Medellín studio directed by the brothers Felipe and Federico Mesa, who understand the architectural project as a provisional pact and a positive expression of the social and ecological constraints around it. Over fifteen years the practice has built more than forty buildings — public spaces, schools, sports facilities, hotels and houses — each negotiated with its conditions rather than imposed on them.

Teaching runs alongside practice: Felipe is Assistant Professor at The Design School, Arizona State University, and Federico at the Universidad Pontificia Bolivariana in Medellín; their research appears in several books, most recently 12 Projects in 120 Constraints. The office belongs to Archipiélago de Arquitectura, and its built work runs from rural schools such as Siete Vueltas to the Hotel Click Clack Medellín.
