Buenos Aires: The Latest Architecture and News

Architecture is often evaluated through what gets built. But in many cases, what matters happens after: how spaces are used, adapted, and made part of everyday life. For Región Austral, winner of ArchDaily's 2025 Next Practices Awards, this is where design really begins. Working across many contexts, the practice approaches public space not as a single object, but as something that needs to be activated, negotiated, and sustained over time. Their projects focus less on defining form and more on creating the conditions for use, with design serving as the starting point.

This approach can be seen across different contexts, from the Olympic Neighborhood Square to the Playón de Chacarita network. While each project responds to a specific situation, both explore how public space can support collective life in areas marked by fragmentation and inequality. Instead of following a predefined approach, the work adapts to different urban conditions, using participation and incremental strategies to shape how spaces function over time.

This week's review focuses on concrete responses to shared urban challenges, including housing affordability, long-term resilience, and the role of cultural and material innovation in shaping cities. The selection spans regulatory measures affecting housing markets in European cities, high-density residential and mixed-income proposals in New York, and major renewal and planning efforts in London, Barcelona, Ulaanbaatar, and Drammen. It also highlights research-driven and built projects in Chicago, Buenos Aires, Las Vegas, and Riyadh that explore circular construction, adaptive reuse, and new models for cultural and public infrastructure. Together, these worldwide projects offer a snapshot of how architecture and urban planning are addressing immediate pressures while laying the groundwork for more resilient and inclusive urban futures across diverse geographic and cultural contexts.

Amid questions, reflections, and debates, the work of Clorindo Testa embodies an innate connection between artistic and architectural experimentation, reflected in many of his built projects, sketches, models, and plans. From the Mariano Moreno National Library to the former Bank of London building in Buenos Aires, his production is of such scope, diversity, and complexity that it constitutes a major source of study, one that also includes unbuilt projects that deserve visibility and recognition on a global scale. In his final years of professional activity, two unbuilt projects of religious architecture highlight Testa’s work not only as an architect but also as a visual artist.

The use of primary colors, pure forms, and concrete represent some of the most distinctive characteristics of Clorindo Testa’s architecture, which is inseparable from his visual art. Reflecting on themes such as living in large cities or the conditions of life in urban spaces, the powerful expressiveness and plasticity of his works, together with the character of the line, his typical color palette, and the frequent presence of the human figure, reveal the importance and meaning he attributed to scales, uses, and perceptions as an architect who never settled for the first idea.

Through his unbuilt projects, built works, and research, Amancio Williams's ideas emerge as the result of a deep understanding of the most advanced trends of his time reflecting on architectural design, urbanism and city planning. By exploring various themes, concepts, and even materials, he aims to create a personal universe that interprets the present as something future-oriented, both international and distinctly Argentine. His proposal "La ciudad que necesita la humanidad" presents linear and layered buildings raised 30 meters above ground, incorporating everything from office spaces to roads and magnetic trains on different levels of a single structure. The Amancio Williams archive at the Canadian Centre for Architecture in Montreal documents Williams' career as an architect and designer from the 1940s to the late 1980s. The fonds documents his work for over 80 architectural, urban planning and design projects, as well as the administration of his architecture practice and his professional activities. Including drawings and sketches, presentation models, photographic materials, such as photographs of models, finished project (when realized), reference images, photographic reproduction of plans, and site photographs, the archive is available to consult offering more details.

The city of Buenos Aires is vast in its area and has a heterogeneous and variable urban fabric in terms of scale. Much of the residential neighborhoods are made up of a mixed-use fabric, where the predominant constructions from several decades ago are the so-called "casa chorizo" and horizontally owned houses, commonly known as PH (Propiedad Horizontal). It is interesting to review how, over the years, these constructions have been modified due to changes in building regulations, which allowed the creation of new typologies, mainly responding to new ways of living within the city. The renovation of these constructions, many of which are used for residential purposes, has also been a conscious response to avoid overbuilding in an already densely populated city. While these projects have been a recurring practice in Buenos Aires for several years now, many young architects of new generations are taking on these challenges, thus generating a trend that seems to have no end and where we find new solutions in each renovation.

Modernism played an undeniable role in the renewal of architectural ideals, contributing a new attitude toward understanding new ways of living, construction techniques, and aesthetics, marking profound changes in the general perception of the world. In Argentina, while it is complex to define modern architectural production periodically, it is possible to mention some architects who began, starting in the 1920s, to engage with these ideas. The intellectual contributions and architectural creations of Alejandro Virasoro, Alberto Prebisch, Ernesto Vautier, Fermín Beretervide, Wladimiro Acosta, Alejo Martinez, Antonio and Carlos Vilar, Juan Kurchan, Jorge Ferrari Hardoy, Antonio Bonet, Abel López Chas, Eduardo Catalano, Eduardo Sacriste, and Amancio Williams, among others, often included original approaches associated with new modes of thought, manifesting an architecture resulting from the analysis of the local and regional conditions of their cities.

At the intersection of the inevitable influence of the international modern movement and Argentinian architectural tradition, the Grupo Austral emerges as a collective of architects proposing a reinterpretation of Le Corbusier's rationalism, adapting it to the particularities of the local context. In this framework, we can speak of an international architecture that is not merely incorporated but can be considered "appropriated" architecture, meaning it is rooted in Argentina's climatic conditions, lifestyles, and local materials. This leads us to question: How does European architecture correspond with the local? Is it the product of similar situations or a process of transferring architectural images, as has happened throughout history? Is it a mix of both factors? Can we talk about appropriated architecture?
