On World Architecture Day 2026: A Call to Build Better, Build Differently, and Share Resources

Audio available

The International Union of Architects designates the first Monday of October as World Architecture Day each year, aligning it with the United Nations' World Habitat Day. This year, both occasions are drawing attention to the global housing crisis as a fundamental element of human dignity, inclusion, and well-being. The UIA's motto reads: "Housing is a Human Right. Build It." The organization calls on architects to contribute to advancing equitable access to housing through design, research, and advocacy. From a holistic perspective, the crisis consists not only of a shortage of residential buildings, but of multiple, interconnected barriers to accessing an adequate place to live. The challenge calls on the dual nature of the architect's work: the capacity for abstract design thinking, and the practical knowledge to transform material reality. For architecture to make the right to housing a reality, both capacities must be put into practice: building new governance structures, different models of shared ownership, designs for alternative forms of cohabitation, and new, environmentally sustainable construction systems.

On the International Day of Democracy: Encounter, Equity and the Symbolic Power of Architecture

Audio available

On the International Day of Democracy, this year the United Nations revisits a traditional idea within the concept: broad citizen participation in government decision-making. On this occasion, the international body invites reflection on how participation and the inclusion of diverse voices in government decision-making can help build a more equitable society. From a spatial perspective, reflection on democracy can move beyond this vertical framing and instead understand it through encounter. What does it mean for a space to be democratic? How can architecture contribute to achieving the principles historically associated with democracy? In the current context of crisis in political organization systems worldwide, this day serves as a platform to question individualization and authoritarianism through the socio-spatial tools available to us.

Building Community Amid Scarcity: The Experience of Usina CTAH

The vulnerability found in countries on the periphery of capitalism, such as Brazil, has wide-ranging consequences that are evident both in statistics and in how the occupied territory is shaped. Peripherization and the struggle to access fundamental rights—such as healthcare, education, and housing—are among these consequences. Addressing these challenges falls to organized social groups striving to build alternatives within this context, as seen in social movements and Usina CTAH, an architectural practice dedicated to providing technical assistance to organized social groups.

What can architecture learn from Paulo Freire?

One of the most important theorists of the twentieth century, Brazilian educator Paulo Freire would have turned 100 on September 19, 2021, had he not passed away in 1997. A month later, Brazil celebrates Teachers' Day on October 15, even as public education faces massive federal budget cuts, continuing a long-standing process of systemic decline in the country's educational system. Against this backdrop, Freire has become one of the world's most widely read and cited theorists in the humanities. Despite this global recognition, his theory has yet to be fully integrated into the literature of architecture and urbanism. Here, we propose a brief reflection on how architectural practices can engage with Paulo Freire's theory.

Women and the self-managed construction site

Often overlooked or dismissed, gender inequality in architecture has consequences for both women and their careers, as well as for the spaces and products created. There is, however, a niche within the construction industry that contradicts this logic, proposing to create a more egalitarian workspace. This article reflects on this inequality and how it is challenged by self-managed practices.

"The most important thing is the people, these people who fight": Paula Constante on housing movements in São Paulo

In late 2020, the documentary Os Mutirões da Leste 1 was released, chronicling the history of the Movimento Sem Terra Leste 1 through each of its projects. The documentary was produced and directed by Paula Constante, who describes herself as a “mother, practicing documentarian, architect, and holder of a master's degree from FAUUSP.” By telling the story of one of the most active social movements in the city of São Paulo, Constante and MST Leste 1 show us the importance of struggle, the collective, affectivity, and the responsibility we must bring to our professional practice. We had the opportunity to speak with Paula and discuss this experience.

Structural Masonry: How It Works and When to Use It

Briefly, structural masonry is a construction system in which the walls of the building perform a structural function, using masonry units arranged in a way that is self-supporting and load-bearing. The walls will evenly distribute the load to the foundation and later into the ground.

Stacked in layers, the bricks, blocks, or stones may or may not be connected by a binder (mortar) and steel reinforcements that heavily influence the mechanical properties of the wall, dimensioned to resist active forces.

What is a mutirão?

This article explores a term widely used to describe self-organized collective labor, but which also carries a meaning of anti-hegemonic struggle when used as a synonym for self-managed projects. The practice of mutirões prompts a reflection on the importance of collective work and grassroots struggle, and how architectural practice and civil construction relate to these themes.
