This week on the TERRAZA podcast, Nicolás Valencia speaks with Chilean architect Blanca Zúñiga, author of the book “Espacio público rural,” published by Sa Cabaña in 2021.

In “Espacio público rural,” Zúñiga develops a photographic project that seeks to capture and value the diverse ways of inhabiting the Chilean countryside in the Maule region.

“In the rural towns of the region, you don't know if the living room of the house is a public or private space because the doors are always open,” Zúñiga explains in this interview.

Located in Lauro de Freitas, a city in Bahia near Salvador, the Acalento School, designed by Carl von Hauenschild, is an example of architecture and pedagogy harmoniously intertwining. This reflects the influence of anthroposophical philosophy on both the architectural design and the Waldorf pedagogy practiced at the school.

Anthroposophy, established by Austrian philosopher Rudolf Steiner (1861–1925) in the early 20th century, is a philosophy that views the human being holistically, encompassing physical, emotional, and spiritual aspects. This holistic approach found fertile ground across various fields of knowledge, such as anthroposophical medicine, biodynamic agriculture, Waldorf education, and architecture itself, significantly influencing the development of organic architecture.

Certain materials offer a wide range of applications, and wood is undoubtedly one of them. This noble material can assume various roles: structurally in tectonics, as floor cladding in finishes, or even as a functional and decorative element in furniture design. Depending on its application, wood tells a different narrative. In facade design, its integration imparts a distinct character; indeed, beyond contributing to the building's identity and aesthetics, it also plays a crucial role in its functionality.

When discussing wood facades, screens and timber batten patterns are recurring elements. Through this approach—in contrast to modular systems—customizable combinations can be created for each project, conveying a unique artisanal beauty tailored to the intended design. Furthermore, wood offers outstanding characteristics in terms of sustainability, solar control, weather resistance, and energy efficiency. Together, these qualities allow the facade to function as a dynamic interface between interior and exterior, mediating light, shadow, and views.

In recent years, the decarbonization of buildings and cities has gained increasing prominence both internationally and nationally. Among the key driving forces is the public sector, through various ministries such as the Ministry of Mines and Energy (MME), the Ministry of Science, Technology, and Innovation (MCTI), the Ministry of Cities (MCID), and the Ministry of the Environment and Climate Change (MMA), which implement different policies, programs, and legislation. Financial institutions like development banks—such as the World Bank and the Inter-American Development Bank (IDB)—and international organizations, including the United Nations (UN), have also played pivotal roles in mobilizing the resources needed to enable the increasingly urgent reduction of carbon emissions.

Negotiating height differences comfortably and using space efficiently is the primary function of stairs. Their invention is not attributed to a single individual or specific civilization; rather, they evolved independently across various cultures throughout history. The earliest evidence of staircases is found in ancient Mesopotamia, Egypt, and the Indus Valley Civilization, with notable examples including the Mesopotamian ziggurats and the Great Pyramid of Giza. The Greeks and Romans further refined the design, and during the medieval period, spiral staircases became common in castles for defensive purposes. The Renaissance introduced even more elaborate and decorative examples crafted from stone, marble, and, later, iron and steel. In modern times, innovations in concrete and precast components emerged, reflecting advancements in materials and engineering. Floating staircases, for example, have become a major trend by visually expanding spaces and enhancing natural light within an environment. They are characterized by an elegant, minimalist design where the treads appear to float in midair without visible support, anchored to a single wall.

The global commitment to net-zero emissions and climate change mitigation presents a monumental challenge for the construction sector—an industry that currently accounts for nearly 40% of global CO₂ emissions, a figure projected to continue rising. Adopting sustainable practices is crucial to improving environmental conditions, with primary objectives including optimizing thermal comfort and reducing energy consumption in buildings. How can we achieve this if not through collective learning and knowledge sharing among different professionals and workers in the sector?

When discussing facades and wood, screens and timber batten patterns are recurring elements. Through this concept—in contrast to modular systems—highly customizable combinations can be created for each project, conveying a unique, artisanal beauty tailored to the intended design. Furthermore, wood offers remarkable qualities in terms of sustainability, solar control, weather resistance, and energy efficiency. Together, these qualities allow the facade to function as a dynamic interface between interior and exterior, also mediating between light and shadow, as well as views.

Public lighting plays a fundamental role in modern cities and has evolved considerably throughout history. In Ancient Greece and Rome, rudimentary methods such as torches and oil lamps illuminated some streets. During the Middle Ages, castles and European city streets used oil lanterns and, later, candles. A significant breakthrough came with the invention of the gas lamp in the late 18th century, first used for public lighting in London in 1807, which improved street visibility and helped reduce crime. Thomas Edison’s invention of the electric lamp in 1879 revolutionized public lighting, and incandescent lamps began replacing gas, providing more efficient and safer illumination.

In an era where we spend most of our time indoors, contemporary architecture offers an innovative approach: dissolving the barriers between inside and outside. This fusion, now an iconic feature of many current projects, reflects a growing desire to live in harmony with nature, promoting a synergy that transcends walls and restores the human connection to the natural environment. Large windows framing landscapes and the use of biophilic design principles blur the boundaries between interior and exterior, creating flexible, light-filled spaces where nature is incorporated into the architectural design. This integration stems from meticulous design choices made possible by technological advances—such as high-performance glazing and smart systems—that enable this connection without sacrificing comfort or energy efficiency.

Metropolises in developing countries share the same mobility challenges: low service quality in public transportation, unequal accessibility, high rates of traffic accidents, congestion, and environmental pollution. There is widespread inequity in accessibility, safety, and comfort within transport conditions that reproduces and perpetuates socio-spatial inequality (VASCONCELLOS, 2000). This is a product of the historical urbanization process of the Metropolitan Region of São Paulo (RMSP), which shaped a territory characterized by income-based residential segregation, concentrated job markets, and an uneven distribution of transport infrastructure (VILLAÇA, 1998). Dating back to the 1950s, policies at the federal, state, and municipal levels favored automobile use. Consequently, this resulted in the low quality and inefficiency of road-based public transit and the sluggish expansion of the high-capacity rail system.

Without tackling urban challenges, we cannot solve the climate crisis. The central role of cities is undeniable: they account for 75% of energy-related greenhouse gas emissions. Urban choices influence and can drive change across all systems that must be decarbonized and made resilient, from transportation to food and energy production. As the 2018 report by the Intergovernmental Panel on Climate Change showed, cities—with their concentration of people, economic activity, and infrastructure—are among the most powerful levers we have to drive decarbonization and build resilience quickly enough to meet the targets of the Paris Agreement.

With the goal of getting to know the architects, projects, and stories behind landmark Portuguese architecture, Sara Nunes, from the architectural film production company Building Pictures, launched the podcast No País dos Arquitectos, in which she speaks with prominent figures in contemporary Portuguese architecture.

In this week's episode, Sara talks with architect João Carlos Santos about the project for the Royal Treasure Museum (Museu do Tesouro Real). You can revisit previous interviews from the podcast No Pais dos Arquitectos and read the transcript of the interview with Santos below.

Designing a limited space like an apartment can be a genuine challenge. Creating new layouts and projects over what has already been imagined by someone else is an exercise that demands a keen eye and respect for the existing structure. In addition to this, there is the need to bring character to the space through interior design without overlooking spatial functionality, ensuring the best possible quality of life for its residents. 

Over the decades, the evolution of urban mobility has directly impacted not only the quality of travel but also the quality of life of everyone living in urban areas—especially those who are socioeconomically vulnerable. In the search for alternatives that can make travel more comfortable, safe, and efficient, managing automobile use combined with improving access to public transit, walking, and cycling is essential. But how does the supply of car parking spaces negatively affect mobility?

A landslide on the Morro da Forca hill struck two historic mansions in the historical center of Ouro Preto, Minas Gerais, this morning, completely destroying them. The buildings were listed by the National Institute of Historic and Artistic Heritage (Iphan). Minutes before the tragedy, the area had been evacuated, and there were no casualties.
