Archinfo, the Information Centre for Finnish Architecture, has announced the theme, curator, and exhibition team for the Pavilion of Finland at the 19th International Architecture Exhibition of La Biennale di Venezia. The exhibition, titled "The Pavilion – Architecture of Stewardship", will focus on the diverse labor involved in constructing and maintaining architecture, from design contributions by architectural workers and engineers to the efforts of construction workers, restoration architects, maintenance staff, and cleaners, all of whom play vital roles in the creation and upkeep of the built environment. Curated by Ella Kaira and Matti Jänkälä from the Helsinki-based architecture practice Vokal, it will use Alvar and Elissa Aalto's Pavilion of Finland to explore architecture as a collaborative endeavor.
In today's architectural discourse, masterplanning is increasingly recognized as a means to reconcile growth with long-term social, cultural, and environmental priorities. Beyond organizing buildings and infrastructure, these large-scale proposals aim to regenerate urban fabrics, adapt historic or underutilized sites, and establish frameworks for inclusive and resilient communities. Submitted by the ArchDaily community, the projects featured in this edition of Unbuilt Architecture highlight how masterplans can respond to contemporary challenges while preparing cities for an uncertain future.
Spanning diverse geographies, from Europe to the Middle East and the Americas, the selected projects reinterpret industrial complexes, cultural sites, and residential neighborhoods through strategies that prioritize sustainability, mobility, and collective identity. Many share a focus on regenerative design: reopening historic canals, creating climate-adapted public spaces, and introducing green corridors and community hubs to reconnect people with their environments. Together, they showcase how masterplanning is evolving into a critical tool for rethinking how cities grow, adapt, and sustain civic life.
Concrete is often seen as the material of modernity, defined by its structural strength, raw finish, and unmistakable gray tone. It became the default palette of 20th-century architecture, a symbol of functionality and permanence. Yet, concrete is not bound to this chromatic identity. Its color is a byproduct of the cement, aggregates, and chemical composition used in its mix, and it can be intentionally altered through pigmentation. Among the many hues explored, red stands out — not only for its visual intensity, but for its ability to root buildings in place, evoke cultural references, and imbue architecture with a material presence that feels both elemental and expressive.
Pigmenting concrete involves the addition of mineral-based colorants — usually iron oxides — during the mixing process. Unlike paints or coatings applied to the surface, these pigments are integrated directly into the concrete mass, ensuring the color permeates the material and remains stable over time. Red pigments in particular are often derived from iron oxide (Fe₂O₃), a naturally occurring compound found in clay, hematite, and other iron-rich minerals. Their deep, earthy hue connects contemporary construction with ancient techniques — from Roman pozzolana mortars to the red earth buildings of West Africa and South America.
Riken Yamamoto, born in Beijing in 1945 and raised in Yokohama shortly after World War II, is a Japanese architect celebrated for fostering community through architecture. After founding his practice, Riken Yamamoto & Field Shop, in 1973, he became renowned for works ranging from social housing, such as Hotakubo Housing and Pangyo Housing, to civic projects like the Hiroshima Nishi Fire Station and Saitama Prefectural University, all unified by modular simplicity. Honored in March 2024 as the Pritzker Architecture Prize Laureate, he was praised by jury chair Alejandro Aravena for "blurring boundaries between public and private," fostering spontaneous social interaction, and "bringing dignity to everyday life" by enabling community to flourish through thoughtful design. In this interview with Louisiana Channel, the architect reflects on the social role of architecture, emphasizing the inseparable bond between housing and context, and the need to create spaces that foster visible, meaningful relationships.
The International Union of Architects (UIA), in collaboration with UN-Habitat, has announced the launch of the third cycle of the UIA 2030 Award. Introduced in 2021, the biennial international prize highlights the role of architecture in advancing the UN 2030 Agenda for Sustainable Development, with a particular emphasis on SDG11: Sustainable Cities and Communities and the New Urban Agenda. Organized by the UIA's UN 17 SDGs Commission, the award recognizes built projects that combine architecture with measurable contributions to the Sustainable Development Goals (SDGs). Structured to coincide with the schedule of the World Urban Forum (WUF), the award will run through five cycles.
The Cristo Rei Cathedral is Oscar Niemeyer's design for the cathedral of Belo Horizonte, the capital of the state of Minas Gerais in southeastern Brazil. Conceived between 2005 and 2006, it is one of the late architect's final projects in the country. The design features a domed structure approximately 60 meters in diameter, suspended by two towering elements rising 100 meters high. Niemeyer referred to the project as a "square," consisting of a cathedral with a capacity for 3,000 people and an external altar designed to accommodate up to 20,000 worshippers for mass and public events. Construction began in 2013 and is still ongoing. Earlier this year, photographer Paul Clemence visited the site, documenting the building process and capturing the emergence of Niemeyer's signature curves.
From the field of architecture and construction, the concept of material reuse is closely tied to circular economy and the reduction of carbon footprints, paving the way toward a more sustainable and responsible future. By incorporating recycling practices, recovery, restoration, and/or the reuse of demolition materials, resource efficiency along with the reduction of energy consumption makes it feasible to experiment with techniques, applications, and new materials that honor the memory of spaces while also bringing new life to both interiors and exteriors.
What does it mean to build with care, using what others leave behind? This question shapes the work of the Matter Matters Lab, an initiative founded by architect and researcher Catherine Söderberg Esper during the isolation of the pandemic. Drawing from experiences across cultures and motivated by a personal transformation during motherhood, Catherine began to investigate everyday waste as raw material for regenerative construction systems. Her first experiment involved gluing her own cut hair using white glue, initiating a radically intimate and handmade approach. Since then, the lab has focused on transforming organic waste into low-impact architectural materials, inspired by Indigenous knowledge systems and aiming to break from extractive models in construction. Projects like the Avocado Bricks, made from discarded avocado seeds, exemplify this approach of local, circular, and rooted in the idea of reciprocity between matter, place, and care, offering a new way of building with waste.
The Museum of Emotions is an annual international design competition that tasks participants with exploring the extent to which architecture can be used as a tool to evoke emotion. The brief calls for the design of a conceptual museum with two exhibition halls: one designed to induce negative emotions; the other designed to induce positive emotions. Participants are free to choose any site of their liking, real or imaginary, as well as choose the scale of the project. The meaning of 'positive' and 'negative' is up for interpretation: What two emotions might a designer consider contrasting? How might an architect conceive spaces which elicit fear, anger, anxiety, love or happiness?
The Museum of Emotions is a 'silent' competition: that is, participants must communicate ideas without text, and must use imagery alone. No form of text, whether design descriptions, annotations or even diagrammatic labels, is permitted.
The Deutsches Architekturmuseum (DAM) in Frankfurt has launched its new exhibitionArchitecture and Energy: Building in the Age of Climate Change on June 14, which will be open to visitors until October 5, 2025. Developed in collaboration with engineer and sustainability advocate Werner Sobek, the exhibition explores the intersections of architecture, energy, and climate, focusing on the environmental impact of the built environment and the role of architecture in mitigating climate change. By framing architecture as both a challenge and an opportunity in the context of the climate crisis, the exhibition seeks to contribute to a broader shift in thinking, one that positions design as a vital component of a sustainable future.
The Getty Foundation's Conserving Black Modernism initiative was launched in 2022 as a grant program to preserve and ensure the legacy of African American architects within the Modernist movement across the United States. In partnership with the National Trust for Historic Preservation's African American Cultural Heritage Action Fund, it supports conservation efforts, training, and educational initiatives to address the historical oversight of significant architectural landmarks and their designers' contribution. For its third funding cycle in 2025, five new buildings will receive critical support, expanding the initiative's reach into new communities with the first projects in Chicago and the Pacific Northwest.
Heritage preservation and economic viability have long been treated as competing priorities in urban development. Architects typically face a stark choice - to design for community continuity or design for financial returns. Contemporary projects in Mumbai render this binary false. Through strategic programming, material choices, and spatial organization, architects enable buildings to generate sustainable revenue while strengthening, rather than displacing, existing communities.
As Expo 2025 Osaka passes the midpoint of its six-month duration on July 13, the international exposition continues to serve as a global platform for architectural experimentation, cultural exchange, and technological innovation. Officially opened on April 13 on the reclaimed island of Yumeshima, the event is organized under the theme "Designing Future Society for Our Lives," and has already welcomed more than 13 million visitors as of late July. Conceived as a space for collaboration across disciplines and borders, the Expo brings together more than 150 national, thematic, and corporate pavilions.
Red clay roof tiles appear in many architectural traditions around the world, despite the cultures being geographically or historically distant. However, this isn't necessarily surprising. Clay is an abundant and accessible building material worldwide, with some studies and other sources suggesting it comprises approximately 10-13% of the Earth's soils. Red tiles, in particular, are often a product of the local soil's mineral content and the firing process. Their widespread use across unrelated regions is less about shared cultural influence and more about material logic: clay is cheap, durable, and easy to work with using simple tools and techniques. In Vietnam, for example, there is a unique and visible tradition of clay tile use that dates back centuries. Regions like Vinh Long, nicknamed the "kingdom of red ceramics", have an abundance of this material, supporting a long history of tile-making. In some parts of Vietnam, these tiles are known as Yin-Yang tiles, due to the concave and convex shape in which they are formed during production.
While Hong Kong is widely celebrated for its iconic harbor view, glittering skyline, and fast-paced urban lifestyle, its origins tell a different story—one deeply rooted in its relationship with water. Before transforming into a dense, vertical metropolis, Hong Kong's architectural identity was closely tied to its maritime context. Today, the city is often associated with slender, glass-clad towers that symbolize modernity. While visually striking in their pursuit of height and form, many of these buildings appear disconnected from their immediate environment, often overlooking natural site conditions, ecological responsiveness, and contextual sensitivity.
Historically, however, this was not the case. Hong Kong's earliest built environments—rural fishing villages in areas like Tai O, Aberdeen, and Shau Kei Wan—emerged through organic, community-driven spatial practices that engaged closely with their surroundings. These coastal and riverside settlements developed architectural systems tailored to the marine environment and to the rhythms of fishing life. Villages were sited around water, and construction strategies were adapted to fluctuating tides, terrain, and social use.
Facing an interconnected planetary climate crisis, biodiversity loss, and resource depletion, regenerative design emerges as a pathway toward building resilient and ecologically attuned rural futures. At the intersection of architecture, agriculture, and local ecosystems, new models of resilient, self-sufficient agricultural practices are emerging. These projects are not grand industrial systems but small-scale, precise, and deeply contextual architectural interventions that create spaces that foster sustainable cultivation while respecting environmental rhythms, local materials, and community knowledge.
