“It feels like boys matter more,” says ten-year-old Molly during an interview for the podcast Visible Women, in which Caroline Criado Perez explains how the lack of data and design around how women and girls use public spaces results in public environments designed solely for the default gender: the male.

Climate-related events could push between 800,000 and 3 million Brazilians into extreme poverty by 2030. The data comes from the Country Climate and Development Report for Brazil (CCDR), released in early May by the World Bank. According to the study, which assesses policies and options for the country to meet its climate and development goals, droughts, floods, and urban flooding cause losses of R$ 13 billion (0.1% of the 2022 GDP) per year.

As part of the second Model: Barcelona Architectures Festival, local architecture firm H3o Architects—led by Adrià Orriols, Joan Gener, and Miquel Ruiz—presented the temporary installation “Nomad Assembly". As one of the five installations featured in this festival curated by Eva Franch i Gilabert and co-organized by the Barcelona City Council and the Mies van der Rohe Foundation, the project was developed to its full materialization in the public space beneath the canopy of the Mercat dels Encants, serving as the main stage for the event.

With a capacity of 42,500 spectators, the first images of the new La Romareda Stadium, home of the Spanish soccer club Real Zaragoza, have been released. Spanish architecture firm IDOM is in charge of the preliminary design of the future stadium, addressing a series of factors considered key in modern sports venues today. These include creating a vibrant soccer atmosphere to enhance the spectator experience, hosting major international competitions, becoming a benchmark in sustainability, utilizing advanced safety and broadcasting technologies, and establishing a landmark for the city, consolidating a stadium for the club, Zaragoza, and the wider Aragon region.

Cities worldwide can save thousands of lives every year through fairly simple measures: traffic calming and speed management. Readjusting vehicle speed limits on urban roads is one of the key initiatives highlighted by the UN and the WHO to help countries meet the target of halving traffic deaths and serious injuries by 2030.

As part of a competition organized by Fundación Casa Wabi, in 2021, the design for the "Orchid Pavilion" by the Mexico City-based firm led by Bernardo Quinzaños, CCA Centro de Colaboración Arquitectónica, was announced as the winner. Designed for Casa Wabi, the project is a permanent, sustainable, and lightweight wooden structure dedicated to the conservation of orchids in the Puerto Escondido, Oaxaca region. This proposal establishes a strong relationship between the biological and cultural diversity of the landscape between the sea and the mountains, integrating local artisanal knowledge in ceramics, clay, palm, and wood with the Japanese philosophy of wabi-sabi 侘寂, which seeks wisdom through simplicity.

The Gustavo Capanema Palace, located in Rio de Janeiro and recognized as a benchmark for Brazilian architecture and arts, is scheduled to reopen to the public in 2024. On the 15th of this month, the National Institute of Historic and Artistic Heritage (Iphan) presented a new proposal for the building's use. From the ground floor to the rooftop terrace, the building will be transformed into a series of spaces dedicated to exhibitions on art and the formation of Brazilian society, while also hosting administrative operations for agencies linked to the Ministry of Culture.

As part of Model: Barcelona Architectures Festival—an event that promotes experimental architecture to reflect on the future of collective life within new metropolitan models and imaginaries, organized by the Barcelona City Council and the Association of Architects of Catalonia (COAC) through the Mies van der Rohe Foundation—various activities took place from April 20 to 30, 2023. This edition featured the participation of Mexican architect Lesly Noguerón Maldonado and architects Diego González Albarrán, Omar Uziel Granados Alejandre, and Zabdiel Ramos Banda, who were internationally selected and awarded in the +Model category for their project “Arca Sonora: entrelazando el paisaje.”

Spanning a 12-hectare site, the Innovation Park (Parque de la Innovación) located in the Núñez neighborhood of Buenos Aires recently inaugurated its public areas, opening free access to a project that integrates businesses, universities, scientific institutions, housing, service areas, and gathering spaces. Aiming to develop an innovation ecosystem, the development is expected to house around 6,000 residents and accommodate approximately 18,000 students.

According to recent data, Brazil's housing deficit stands at 5.876 million households: 5.044 million in urban areas and 832,000 in rural areas. In percentage terms, this figure corresponds to 8.1% of the country's total stock of private, permanent, and improvised dwellings. Aiming to address, either fully or partially, this massive social debt, the Minha Casa Minha Vida (MCMV) program, launched in 2009, began offering affordable housing to low-income families.

Singapore, China, Dubai (United Arab Emirates), London (England), Toronto (Canada), Hong Kong, New York (USA), and Paris (France) are examples of locations that have been verticalizing more intensely in recent years, adopting a series of measures to curb urban sprawl while seeking to meet the demand for more housing and infrastructure. Consequently, these regions have seen a growing number of skyscrapers—or tall buildings, as they are also called—being constructed in their neighborhoods, including central and historic areas.

As part of an initiative by the Federation of Associations of Architects of the Mexican Republic, a national competition was launched to design an affordable housing prototype in Los Pirules, Celaya, Guanajuato. The Municipal Housing Institute of Celaya (IMUVI) currently holds a land reserve in the northeast of the municipality, where it plans to develop a social housing complex. In collaboration with FCARM, they launched this competition to spark architectural reflection on the potential of social housing and the city. The prototype had to adapt to the post-2022 economic reality and living patterns, focusing on providing constructive alternatives and solutions responsive to the housing complex's urban, sociocultural, and environmental context.

This article by Mónica Bustos Peñafiel was originally published in issue 113 of ARQ magazine. It reflects on the Emergency Housing Plan, tracing the history of the deficit and the challenges posed by the various government plans designed to address it.

Water scarcity is seasonal in many regions, and harvesting and storing rainwater is an effective way to prepare. Another approach is to reuse domestic graywater. Gardens and green roofs can be used as cisterns for this purpose.

João Manuel Feijó, an agronomist and specialist in biophilic design, explains that graywater is wastewater from showers, sinks, bathtubs, washing machines, and dishwashers. It accounts for a large percentage of residential wastewater: between 50% and 80%.

The satisfaction of living longer is closely tied to opportunities to lead an active life, stay engaged, and feel integrated into society. To this end, the built environment must support these goals through flexible structures that adapt gradually to users' needs, regardless of age.

The real estate sector is beginning to realize the immense potential of architecture focused on health quality and increased human life expectancy. As we look to the future of real estate, we can expect a smarter use of technology, along with innovations and new metrics to establish a better understanding of well-being and its relationship with both the natural and built environments. This quality standard will drive an exponential increase in sales by making properties flexible and adaptable throughout the different stages of their residents' lives.

Four years after receiving the archive of Espírito Santo-born architect Paulo Mendes da Rocha, Portugal's Casa da Arquitectura is opening two exhibitions dedicated to the Brazilian winner of the Pritzker Prize (2006) and the Golden Lion at the Venice Biennale (2016). The larger of the two, featuring 138 original drawings, dozens of photographs, and other documents, is dedicated to the architect's built work and seeks to expand the notion of geography that runs through Mendes da Rocha's production.

It could be a parklet, a mini-plaza, or an asphalt painting to redesign a street and repurpose a public space. Cities around the world—including in Brazil—are using temporary interventions to catalyze long-term projects that make streets safer, creating inclusive, high-quality public spaces.

These initiatives employ a technique known as tactical urbanism, which promotes the reclamation of urban space by and for its primary users: people. This movement is gaining momentum amid an urban crisis in which governments struggle to provide a growing population with basic urban services such as housing, quality transport, and adequate open spaces that enable safe, active mobility. 

The Association of Young Architects of Catalonia (AJAC) of the Architects' Association of Catalonia (COAC) has announced the 22 selected projects in the 13th edition of the AJAC Awards—a recognition for young architects under the age of 40.

The headquarters of the College of Dentists of the Province of Santa Fe is located in the city's macrocenter, a metropolitan urban area rich in cultural and heritage buildings. By incorporating concepts of innovation, sustainability, functionality, flexibility, and technical and economic feasibility, the project aimed to foster integration between the public sector and the association's administrative activities through a flexible design capable of adapting its functional layout.
