Few may have heard of Hermosillo, a Mexican city of 850,000 inhabitants located in the middle of the desert, just 280 kilometers south of the United States border. It is a city of great strengths, but also immense challenges. In an increasingly urbanized world, cities have become platforms for innovation and change, particularly in developing countries. While megacities like Bogotá, Lima, and Mexico City struggle to distribute goods and services to their sprawling populations, intermediate cities like Hermosillo have the potential to offer a more sustainable alternative.

Construcciones Modernas, S.A. is a series comprising an album of popular, remembered, and forgotten buildings in Mexico City—a record and the beginning of an atlas. It is a subway line featuring all the architectural icons missing from the train cars, a tribute to the city, its modernity, and its decay.

Alberto Cruz, one of the Chilean architects who re-founded the School of Architecture of the Pontificia Universidad Católica de Valparaíso and founder of Amereida and the subsequent Open City, left behind more than 2,200 notebooks and folders, 200 drawings in various techniques, formats, and mediums, and around a thousand documents when he passed away in 2013.

Five years earlier, his granddaughter, historian Sara Browne, began working with Cruz to catalog his private output. Today, this entire archive is part of the Alberto Cruz Covarrubias Foundation, a space dedicated to honoring the memory of the 1975 National Architecture Award recipient.

In this email conversation with Browne, the historian examines the challenges of conserving and digitizing this historic archive, while also reflecting on Cruz Covarrubias's legacy.

CityMakers is working with ArchDaily to publish a series of articles, conversations, and interviews with various actors in city co-production, who are behind the Barcelona CityMakers Lab 2019, an event taking place from October 14 to 20.

On this occasion, we feature Oriol Estela Barnet, general coordinator of the Barcelona Metropolitan Strategic Plan, who will give a MasterClass at the Barcelona CityMakers Lab 2019 addressing the concept of “a third generation of strategic urban plans: the case of Barcelona.”

The family of José Antonio Coderch [1913-1984] has handed over the Catalan architect's significant archive to the Reina Sofía Museum in Madrid. With this acquisition, the renowned Madrid museum seeks to follow the path forged by other contemporary art institutions, such as the MoMA in New York or the Pompidou in Paris. Because these institutions already feature dedicated architecture departments, the Reina Sofía aims to expand its own holdings, incorporating both architectural movements and the individual professionals who shaped the art of building. This initiative has been promoted for several years under the leadership of the museum's director, Manuel Borja-Villel.

The archive, which was stored in a utility room at the home of one of Coderch's children, consists of 9,800 documents organized across 875 folders and dating from 1941 to 1978. It includes plans and sketches of his architectural projects; designs, photographs, and negatives of his works, alongside family photos; professional correspondence; invoices and receipts for each project; as well as magazines, books, publications, and scale models; portraits of the architect, several of his numerous awards, and personal belongings. 

Earthen construction remains highly relevant today, spanning the preservation of architectural heritage, new projects seeking sustainable horizons, and numerous training programs offered by institutes and universities. Yet we cannot overlook one of the major driving forces behind this building material: self-construction. Thanks to its technical advantages and accessibility, communities worldwide have chosen to build their settlements with earth. Consequently, construction becomes a collective exercise where every individual can contribute to shaping a shared future.

In this article, we look at how the NGO Terrachidia works with the community of Mhamid in Morocco to rehabilitate public spaces chosen by local residents. Supported by volunteers, they rescue regional building traditions, successfully preserving and highlighting the local knowledge embedded in places where the pursuit of modernity has led to abandonment, but which remain deeply valued by those who inhabit them.

Exhibited in a parallel exhibition at the 2018 Venice Biennale, the Tropi-Co-Re Housing project by SUMA Arquitectos reflects on the intersection of urban and architectural design within the low-income residential context of an equatorial/tropical climate, investigating alternative material systems for its construction, such as bamboo truss structures and folded metal plate roofs.

Read on to explore the project in detail, in the words of its designers.

The core of Castilian modern architecture, and indeed of the 20th century, emerged from the work of Rafael Aburto [1913-2014] and his contemporaries—this forgotten generation. An interwar generation whose trenches were fought not only on the battlefield, but also within architecture. This cohort of architects had to confront both the ravages of the Spanish Civil War and a sterile traditionalism, surrounded by professionals who had read, known, and seen almost nothing. Tradition—specifically, Spanish tradition—was what sustained everything. Unsurprisingly, the Civil War itself dealt a generational setback to the profession, impacting not only Aburto's peers but also those to come. 

The generational divide was defined solely by the experience of having fought in the war. Oíza was eighteen when it broke out; Sota, Cabrero, Coderch, and Aburto were called to battle, mostly fighting on the Nationalist side. Once the war ended, Spain was unrecognizable compared to its pre-war self, and architectural thought was no exception. Returning to the profession in the 1940s, architects faced an outdated, practically useless tradition, alongside a precarious modernism devoid of depth or knowledge. This is why figures like Aburto broke through—these postwar architects who took on the role of pioneers, or at least demonstrated their determination to break free from academic constraints and embrace their own modernism.

Whether seeking distraction, escape, or reflection, metro passengers shorten their commutes by checking their phones, reading books, or listening to music. For Chilean photographer and civil engineer Felipe Lavín, this conceals a contradiction. "Commuting en masse is a highly social act, yet at the same time, it is deeply solitary. As Marc Augé notes, in the metro we constantly brush against the lives of others without ever truly encountering them," Lavín says in conversation with ArchDaily.

Alexandra Cohen presents her master's thesis on the systematic cartographic analysis of the morphological intersection between the Cerdà urban plan and pre-existing urban structures in Barcelona, Spain. Through her cartographic work, she aims to demonstrate how two highly distinct urban forms can integrate to bring immense value to the city, preserving history within a modern plan.

Colombia's topography features both plains and mountainous areas. Despite the challenges this poses for urban development, the country's major cities—from its capital, Bogotá, to Medellín and Cali—have been founded upon it. While this topography has posed significant challenges for construction and mobility, it has also paved the way for innovation, inspiring architectural projects that seamlessly integrate with the mountainous terrain, adapt to their specific altitude, and reflect regional culture.

As part of the Abierto Mexicano de Diseño 2019 (AMD2019), Jumbo, an international company focused on the development of urban spaces and furniture, presented the play sculpture “Infinito,” designed by Ariel Rojo. The project stems from the desire to design a line of urban elements that stimulate a sense of adventure and play through a range of play sculptures. These address not only an aesthetic responsibility to users, the city, its parks, and playgrounds, but also introduce an original approach to how children play and learn.

As part of the design program at AGO Projects—a multidisciplinary space focused on promoting design, photography, and architecture, based in New York, which opened its doors in Mexico City just a few weeks ago—the exhibition "Otro Reino" has opened. The showcase features previously unseen and well-known pieces by Isabel Abascal and Alessandro Arienzo's architecture studio, LANZA Atelier, and is complemented by "Neo-neo," a collection of ceramics based on urban concrete accidents by MT Objects.

On December 4, the opening of the Provincial Preliminary Design Competition for Cultural Spaces in Villa Carlos Paz took place. 

The format involved intervening in three emblematic urban spaces under a single competition, but with individual prizes awarded for each site. The goal was for participants to achieve aesthetic and architectural proposals that would transform each space into a city landmark.

These are the three winning projects:

Through sculpture and drawing, Ivan Kurov (Mexico City, 1982) explores nature and transformation in their broadest definitions. While the former allows him to study the chemical properties of materials and the physics of objects, his paintings frame the confrontation between the organic landscape and the intervention of human architecture. For Kurov, art in its fullest sense is achieved outside of discursive intention, occurring when the hand works the material without the mediation of a concept. Consequently, his pieces emerge from the autonomy of processes and from matter in the freedom of its essence. The result is spontaneous and fluid, much like the artist's own conversation.

For the third consecutive year, National Monuments Day will take place during the first weekend of May throughout Argentina, coordinated by the National Commission of Monuments, Places, and Historic Assets of the National Ministry of Culture.

Colombian firm DARP has won second place in the design competition for the memorial space at the former Mónaco Building in Medellín, Colombia. Organized by the EDU and the Colombian Society of Architects (SCA), the international competition sought to design a space of memory and reflection on the period between 1983 and 1994, located on the site of the demolished building that was once the home of drug trafficker Pablo Escobar.

On Tuesday, April 23, Archiprix Chile 2019 announced the winners of this year's edition at the Centro Cultural Estación Mapocho, honoring the thesis projects of young Chilean architects with three top prizes and three honorable mentions. The award ceremony was preceded by a lecture by Martín del Solar, co-founder of Grupo Talca, a Chilean practice featured in the 2016 Venice Biennale.

Originally published in ArquitecturaAhora, architect Ana Sugranyes explores the origin and evolution of the concept of the right to the city, from 1960s Paris to its global expansion.

In the name of social integration or sustainability, the United Nations New Urban Agenda (2016) also incorporated a reference to the right to the city. “Words, then, are of no use: they are just words,” says Alberti. Meanwhile, Chile maintains its high level of income inequality, which has a direct, correlative effect on the deep socio-spatial segregation of its territories and cities; this, in turn, corresponds to worrying levels of social, cultural, and structural violence. 

Since the mid-twentieth century, Latin American cities have undergone metropolization processes in which transportation has been heavily impacted by the exponential growth of private vehicle use. This is driven by rapid, unregulated urban sprawl that causes cities to spread extensively across the territory. This physical expansion is compounded by deficient public transit management and weak domestic socioeconomic conditions, both of which severely constrain the development of transportation systems.

Córdoba, Argentina's most populous city after Buenos Aires, is a prime example of this paradigm, featuring one of the largest urban footprints in the world at 576 square kilometers (excluding its metropolitan area). Its physical structure is radiocentric, with transport corridors converging in the city center, creating a dense core where services are concentrated and an ever-expanding periphery.

Today, when it comes to urban planning, the design and pursuit of inclusive cities is generally promoted. That is, fostering collective environments where all sectors of society can thrive.

How much easier would this task be if spaces were created where different segments of society could express their needs regarding how they live?

“Leo Leo! Que Ves? La ciudad contada por los niños y las niñas” is a project that originated in the city of Córdoba in 2017, within the framework of the artistic and cultural activities program of the Undersecretariat of Culture at the National University of Córdoba. It continues to develop activities such as “Ciudad niñez-ca,” led by Paola Antonietti and workshop facilitators Camila García Reyna, María Paz Pérez Roque, Rocío Maldonado, Gabriela Soto, and Matias Zanetti, alongside FAUD's Urbanism 1A department and the City and Territory Studies Workshop.

We explore this project through the words of its creators.

Mares is an urban transformation and social economy project developed by estudio SIC, VIC (Vivero de iniciativas ciudadanas) and TXP (Todo por praxis) in Madrid, Spain. The project reclaims four former buildings across four different districts of the city, converting them into innovation hubs. Each hub is linked to key urban challenges: Mobility, Food, Recycling, Energy, and Care.

While many of the homes built during the Modern Movement—as design experiments on new ways of living—fostered the early emergence of "programmatic hybrids" by typically linking the residences of artists, painters, or architects with their workspaces (one need only recall, for instance, the atelier Le Corbusier designed for painter Amédée Ozenfant in 1922), today, new work models and hyperconnectivity have further driven the development of a new typology where workspaces are integrated into residential architecture. Architects, writers, photographers, designers, and painters increasingly choose to integrate their studios and workshops into their homes, merging living and working into a single whole.

Concéntrico is an International Architecture and Design Festival that, through a democratic approach open to all citizens and visitors, aims to reflect on the urban environment and the city.
