Founded in 2002, Posto 9 creates purposeful architecture, balancing creativity, function and urban context.

About us

Founded in 2002 by Joana Castanheira and André Ferreira, Posto9 Arquitectos brings together nearly 25 years of experience in the development of architectural projects across different scales and functional programs, with a particular focus on the education and housing sectors.

Our practice is based on a rigorous and collaborative approach, where each project is understood as both an intellectual and technical challenge. Close relationships with clients, continuous dialogue with public and private entities, and collaboration with trusted partners in engineering and landscape design are essential pillars of our working method.

Through close project follow-up, continuous updating of applicable regulations, and a persistent approach to licensing processes, we ensure compliance with deadlines and the successful delivery of each project. We test, refine and persist until final approval — because it is through this rigor that we define the quality of the outcome.
