PESA
estudio de arquitectura

Based in Rosario and Quito, we understand architecture as a critical and situated practice. 
Our work is grounded in close readings of territory and its cultural, technical, economic, and material conditions,  approaching each architectural intervention as a specific response to context. 

Our practice includes residential, commercial, cultural, and public architecture, as well as architectural and urban design competitions. We approach architectural production as an integrated process that connects research, design, and construction, allowing each project to function simultaneously as built work and as a form of applied research. 

In parallel, we maintain an active academic practice in local universities, where we develop teaching, research, and university outreach projects focused on architectural design, territory, and contemporary urban conditions. 
We are involved in collective and editorial initiatives related to architectural pedagogy and local practice. We have presented our work and taught in academic institutions in Argentina, Ecuador, Mexico, and the United States, and have participated as invited professors and jurors.

Con sede en Rosario y Quito, entendemos la arquitectura como una práctica crítica y situada. Nuestro trabajo se basa en una lectura atenta del territorio y de sus condiciones culturales, técnicas, económicas y materiales, abordando cada intervención como una respuesta específica a su contexto.

Desarrollamos arquitectura residencial, comercial, cultural y pública, así como propuestas para concursos, integrando investigación, diseño y construcción como un proceso continuo.

En paralelo, desarrollamos una práctica docente activa en universidades locales, donde desarrollamos proyectos de investigación y extensión universitaria centrados en el proyecto arquitectónico, el territorio y las condiciones urbanas contemporáneas. Participamos además en iniciativas colectivas y editoriales vinculadas a la pedagogía arquitectónica y a la práctica local. 
Hemos presentado nuestro trabajo en instituciones académicas de Argentina, Ecuador, México y Estados Unidos, y participado como profesores y jurados invitados.
