Across South America, architecture is increasingly being understood as a collective act. Rather than imposing external views, many studios and designers are building with and for communities, learning from their local practices, materials, and ways of inhabiting. These projects are repositioning the architect's role from an author to a facilitator, transforming design into a participatory process that centers collaboration, care, and mutual respect.
What unites these efforts is not style or scale, but a shared belief: architecture emerges from collective dialogue, not imposition. From rural Ecuador to the urban peripheries of Brazil, Colombia, and Paraguay, these projects reveal how social engagement and local making produce spaces that are sustainable not only environmentally but also socially. They respond to inequality not through top-down solutions, but through co-authorship, offering spaces that reflect the needs, knowledge, and agency of the people who use them.
There are places in the world where temperatures already exceed fifty degrees, and others where water levels rise meters above expected levels. Meanwhile, in the heart of São Paulo, architects, researchers, artists, and communities come together to ask: how can we inhabit the Earth in times of extremes? This question drives the 14th International Architecture Biennial of São Paulo, held at the Oca in Ibirapuera Park, focusing on the theme Extremes: Architectures for a Hot World. More than an exhibition, it is a call to confront the climate crisis, social inequality, and the urgent need to reinvent ways of living.
Unlike previous editions, which were spread across multiple locations in the city, curators Clevio Rabelo, Jera Guarani, Karina de Souza, Marcella Arruda, Marcos Certo, and Renato Anelli chose to concentrate this year’s edition under a single roof, allowing the curatorial narrative to unfold clearly and directly. The entire journey is there, organized into sections that weave together ancestral practices and emerging technologies, material experiments and critical perspectives, local projects and global debates. The Oca thus becomes a crossroads: a space where diverse architectural visions overlap, offering a platform for collective reflection on society and the environment.
India carries an ancient lineage of tradition that has long shaped the very conception and crafting of its cities. Vastu Shastra is one such tradition, more a science than a belief, intimately woven into the principles of architectural design. The practice remains widespread and highly regarded, with 93% of homes designed to align with Vastu principles. As India urbanizes at an unprecedented pace, projected to add 416 million city dwellers by 2050, Vastu Shastra continues to influence billions of real estate decisions amid the trials of modern city living. How might an 8,000-year-old spatial science evolve to guide the design of cities housing millions?
In South AmericanIndigenous communities, a child’s place is wherever they choose to be. Babies crawl on the earthen floor, approach the fire, investigate anthills, and experience the world with their whole bodies. They learn by feeling: discovering limits, recognizing dangers, and gathering lessons no manual could ever teach. In urban contexts, by contrast, children are often confined to spaces designed for adults, filled with rules that—though well-intentioned—tend to distance them from essential experiences. Rather than judging which model is “better,” what matters is recognizing that when cultures observe one another, there is always room for learning.
From an architectural perspective, this childhood with little freedom of time and movement challenges us to rethink how we shape daily environments. Why restrict spontaneous exploration to controlled settings? Why create physical and symbolic barriers between children and the natural world? And, above all, how might contemporary architecture break away from this paradigm and, inspired by Indigenous childhoods, design environments that restore to children their wild, curious, and complete dimension?
Across Asia, bamboo scaffolding has symbolized an intersection of traditional knowledge and modern construction. Hong Kong's skyline is shaped by intricate bamboo scaffolding, yet this time-honored craft is steadily vanishing from the region. Moving east, Indian cities still utilize bamboo scaffolding on building sites throughout the subcontinent, revealing a different kind of paradox.
Titled "Chinampa Veneta", the Mexican exhibition for the 19th International Architecture Exhibition – La Biennale di Venezia seeks to promote reflection on how we inhabit, cultivate, and design the world we share. In the face of the global ecological crisis, the project draws attention to chinampas, an ancient Mesoamerican agricultural system with more than four thousand years of history. This ancestral knowledge, interweaving landscape, infrastructure, and technique, is reimagined in the context of the Biennale, activating a living environment within the city of Venice. The Mexican Pavilion consists of two "enactments," one located in the Arsenale and the other built on water.
Vernacular architecture often utilizes locally sourced materials and construction practices honed over centuries. This approach raises questions about its potential relevance for contemporary design challenges. The prevalence of high-rise developments globally, often relying on sealed envelopes and mechanical climate control, contrasts with historical architectural practices. Traditionally, regional architectures emerged from local communities, fostering distinct cultural identities and integrating passive systems for ventilation, cooling, and heating, often utilizing natural elements. The Hanok, traditional Korean houses, serve as a case study. Beyond their current role in tourism, they are also an example of how vernacular knowledge can provide passive climate-response strategies that align with the current principles of creating environmentally friendly buildings.
In 1982, at a conference on earth building in Tucson, Arizona, an unusual presentation challenged everything architects thought they knew about rural resources. Instead of focusing on construction techniques, the presenter, architect Pliny Fisk III, spread out a series of hand-drawn maps that revealed something extraordinary - rural Texas wasn't resource-poor, as conventional wisdom suggested, but material-rich beyond imagination. The maps showed volcanic ash perfect for lightweight concrete, caliche deposits stretching across vast territories, and mesquite forests that could supply both hardwood flooring and insulation. The revelation redefined prevailing notions of value in architecture.

At the 19th International Architecture Exhibition of La Biennale di Venezia in 2025, the Lebanese Pavilion, curated by the Collective for Architecture Lebanon (CAL), presents "The Land Remembers," an exploration of ecocide and environmental healing. Selected by Lebanon's Ministry of Culture and the Lebanese Federation of Engineers, CAL is a non-profit organization co-founded in 2019 by Shereen Doummar, Edouard Souhaid, Elias Tamer, and Lynn Chamoun. Their curatorial vision aims to transform the pavilion into a fictional institution, the Ministry of Land Intelligens, dedicated to confronting environmental devastation and proposing strategies for ecological restoration.
Adjaye Associates has revealed the design for the International Children's Cancer Research Centre (ICCRC) in Kyebi, Ghana. Commissioned by the Wish4Life Foundation, the project marks a step in the development of pediatric healthcare in West Africa. Situated on a 225,000-square-meter site along the eastern slopes of the Atewa Range, the ICCRC is envisioned as an integrated facility dedicated to healing, research, education, and community engagement. It will be the first center in the region solely focused on the treatment of childhood cancers. The project is currently on view at the Time Space Existence exhibition, part of the Venice Architecture Biennale 2025, held at Palazzo Bembo until 23 November 2025.
As artificial intelligence (AI) becomes increasingly embedded in society, it's essential to pause and reflect on the foundations that sustain it—and the dimensions to which it extends. At the heart of AI's learning are datasets, whose structure and content shape how these systems interpret and respond to the world. This reliance creates a deep interdependence—one that not only informs AI's capabilities but also defines its potential blind spots. In light of this, we must ask: What forms of understanding might this process exclude, especially those not easily captured in digital form?
The 2025 iteration of the Time Space Existence exhibition is set to attract audiences from May 10 to November 23. Organized by the European Cultural Centre (ECC) in Venice's renowned venues—Palazzo Bembo, Palazzo Mora, and Marinaressa Gardens—this seventh edition brings together a diverse cohort of 207 architects, designers, artists, and researchers from over 52 countries. All contributions are curated under the theme of "Repair, Regenerate, and Reuse" as an exploration of architecture's capacity to engage with critical environmental, social, and cultural challenges. Highlights of the Special Projects section include ArchDaily's inaugural exhibition, presenting six architecture offices previously recognized as Best New Practices as emerging voices in the field of architectural innovations.
Much before humans constructed their first permanent shelters, they discovered the protective power of animal hides as a barrier against harsh environmental conditions. This fundamental principle of building with flexible materials finds influence in the architecture of today, despite the lack of strong precedents that have been lost to time. Textiles served as humanity's first architectural elements, predating ancient construction methods like stone masonry. The relationship between textiles and shelter would go on to shape the entire history of architecture, from prehistoric settlements to modern skyscrapers. What lessons might these ancient origins of architecture hold for future advancements in building design?
The Australian Institute of Architects has announced the Creative Directors for the Australia Pavilion at the upcoming 19th International Architecture Exhibition - La Biennale di Venezia in 2025. Selected to lead this project, Dr. Michael Mossman, Emily McDaniel, and Jack Gillmer will present "HOME", a pavilion dedicated to Australia's natural environment and Indigenous knowledge systems.
Thousands of years ago, a chain of volcanoes and hills formed a valley that became home to five lakes. According to indigenous mythology, this area served as a key reference point for the founding of the ancient Tenochtitlan, marked by the signal of an eagle perched on a cactus, devouring a snake. At the height of its splendor, the city was organized within an intricate system of causeways, many of which still serve as main thoroughfares, along with canals connecting the five water bodies. Over time, events such as colonization, independence, revolution, and modernization transformed its structure and name, leading to what is known today as Mexico City.

Sumayya Vally, architect, curator, and founder of Counterspace architecture office, joins the jury for the 2024 Obel Award. This international architectural prize, organized by the Henrik Frode Obel Foundation, honors projects that significantly impact people and the planet. The 2024 theme, "Architecture WITH," invites a re-examination of the architectural profession, emphasizing collaborative and co-creative processes that integrate diverse bodies of knowledge into the core of design. Vally's perspective on redefining architectural roles aligns with the theme's focus on non-hierarchical, co-creative approaches.
Reflecting on the past is often viewed as nostalgia or, from a more critical standpoint, as a sign of regression. However, looking back can offer valuable insights into a society that sometimes appears overly focused—if not obsessed—with the future and technology. In architecture, this reflection allows us to reconnect with our roots and appreciate the knowledge accumulated over generations. It invites us to explore how our ancestors designed durable structures adapted to their environment. Refined through centuries of observation, experimentation, and likely even errors, these systems demonstrate a profound understanding of local materials and building techniques.

According to the United Nations, indigenous people are "place-based" ethnic cultures that have not migrated from their initial homeland. In today's world, with human-caused climate change driving extreme weather events and a growing demand for authenticity and cultural diversity, architects are increasingly turning to indigenous knowledge systems not only as sources of inspiration but as viable solutions to adapt and respond to local and global challenges. As traditional custodians of the land, Indigenous communities possess a profound understanding of their ecosystems, locally available materials, cultural norms, and social constraints. This knowledge holds insights valuable for shaping contemporary architecture, helping it adapt to both the people and their environments.
Vernacular and indigenous practices are emerging as a foundation for architectural reimagining, informing spatial lays, the choice of materials, and building techniques while also allowing for the integration of innovation and contemporary expression. This careful blend of tradition and modernity can have a significant impact in terms of sustainability, as architects who adopt the indigenous approach to harnessing available resources can not only create structures rooted in their context but also minimize the ecological impact of the construction. Additionally, collaborating directly with Indigenous communities leads to projects that prioritize community participation, cultural sensitivity, and sustainable development.
