Colectivo C733: The Latest Architecture and News

©OBEL Foundation

The OBEL Foundation has announced "Systems' Hack" as the focus of its 2026 cycle, setting the conceptual framework that will guide the foundation's activities and the selection of the next OBEL Award. Founded in 2019, OBEL recognises architecture's potential to act as a tangible agent of positive social and ecological change, supporting approaches that expand how the built environment is defined and shaped. The 2026 theme calls on architecture to critically engage with the systems that underpin contemporary society, including infrastructure, energy, food, water, education, and information, and to examine how these interconnected networks might be reconfigured in response to accelerating global challenges.

The making of a place is not a difficult thing in principle; it is enough for people to come together in a regular set location for a purpose or activity, and a space becomes. This does not disregard the fact that a physical element needs to accompany this gathering for a space to become sheltering, accommodating, and alluring. This idea of the space that emerges from intent can most definitely be seen in one of the most ancient of functions, which is food or produce markets.

For a market to become, the architectural element can be as simple as a light roof, which would harbor merchants and offer a non-spoken boundary to the place, or it can be as resourceful as adaptively reusing an existing building or site to fit new needs. Finally, it can be a temporary and lightweight structure pitched for certain events or needs and then removed to be used elsewhere, or for other means.

In this interview with Louisiana Channel, Mexican architect Gabriela Carrillo introduces us to the challenges that drive her work, particularly the projects carried out as a member of Colectivo C733, in which she currently participates alongside Carlos Facio, José Amozurrutia, Eric Valdez, and Israel Espin. Through an exploration of her definition of architecture, she offers reflections on the design of public spaces, the relationship between architecture and land art, and the role of the preexisting in the transformation of space. She defends architecture as a "powerful tool" for fostering connections between people and their environment, defining her practice as optimistic.

The UIA World Congress of Architects is an international event for architectural dialogue organised by the International Union of Architects (UIA, by its French acronym), a non-governmental organisation that unites national associations of architects from over 100 countries, representing more than one million professionals. The first UIA Congress of Architects, which also marked the institution's founding, was held in Lausanne in 1948 during the post-war reconstruction period. Since then, UIA congresses have been held every three years in a different city within a member country, serving as the organisation's main recurring event. In 2026, the Congress will be held in Barcelona, and UNESCO has consequently designated the city as the World Capital of Architecture 2026. Each Congress focuses on a key topic relevant to the profession, articulated through a central theme. Recent themes include Copenhagen 2023: "Sustainable Futures. Leave no one behind." and Rio 2020–2021: "All the worlds. Just one World." The topic for 2026 is "Becoming. Architectures for a Planet in Transition," welcoming renowned figures in contemporary architectural thought and practice for a broad and critical overview of the possible futures of architecture.

Contemporary Mexican market architecture frequently draws inspiration from its pre-Hispanic precedents. The Tlatelolco Market in ancient Tenochtitlan, for example, featured a large, stone-paved open square with designated "streets", which were divided into sections for specific goods, serving as a significant gathering point for social and economic exchange. Similarly, the tradition of the Tianguis, an ephemeral market typology within the broader Mesoamerican tradition, also arranged stalls in aisles within a public plaza, reflecting organizational principles seen in Tlatelolco. These historical models established a base for the tradition of marketplaces in Mexico and the countries in Central America, where they merge public space and structured layouts for commerce. Today, even though many of Mexico's commercial spaces, notably Mexico City's Central de Abasto and other markets such as the Jamaica, Merced, and San Juan Markets, have taken on a stationary approach to serving their communities, tianguis maintain their foothold in Mexican society.

From December 2 to 6, the XIII Ibero-American Biennial of Architecture and Urbanism (BIAU) will be held in Lima, Peru, under the theme CLIMATE: Actions for Good Living. Since 1998, the BIAU, promoted by the government of Spain through the Ministry of Housing and Urban Agenda (MIVAU), in collaboration with the Higher Council of the Colleges of Architects of Spain and with the support of the ARQUIA Foundation, aims to disseminate good practices in architecture and urbanism in Ibero-America, fostering a space for discussion around contemporary challenges shared between Spain and Latin America. Weaving bridges of knowledge between both continents, the BIAU opens its doors once again, now in Lima.

Recognized for completing 36 distinct yet cohesive public projects across Mexico in just 36 months, Colectivo C733 showcases the impact of collaborative design on public spaces and communities. The 36 projects were part of a national effort to revitalize vulnerable urban and rural areas in Mexico, earning them the 2024 Obel Award focused on the theme of "Architectures With". The team behind the designs, Colectivo C733, is a collaborative group formed by the joint offices of architects Gabriela Carrillo (Taller Gabriela Carrillo), Carlos Facio, and José Amozurrutia (TO), along with Eric Valdez (Labg), and Israel Espin. In a recent conversation with ArchDaily's Editor-in-Chief, Christele Harrouk, the collective discussed their approach to public architecture, the process of integrating diverse voices, and remaining flexible to the challenges of local conditions.

The 2024 Obel Award has been granted to Colectivo C733 for their unique achievement in completing 36 public projects across Mexico over a span of just 36 months. These projects have begun as part of a nationwide initiative led by Mexico's Secretariat for Agrarian, Land, and Urban Development (SEDATU). Collectively named the 36x36 projects, the varied interventions have successfully revitalized a wide range of vulnerable urban and rural areas through a collaborative and community-focused approach. This aligns with the Obel Award's 6th cycle overarching theme, "Architectures with," highlighting initiatives that positively impact both people and the planet.

In 2019, the Secretariat of Urban Development hired the Faculty of Architecture at the National Autonomous University of Mexico to organize a competition to develop small-scale public works in vulnerable regions of northern Mexico. At that time, architects from the mentioned university—Gabriela Carrillo, Carlos Facio, José Amozurrutia, Eric Valdez, and Israel Espín—came together to participate in their proposal for this challenge. Believing in the importance of forming a team and understanding that architecture emerges from moments of collective discussion, exchange of ideas and positions, and sharing knowledge and experience, they formed the architectural collective C733.
