On November 21, 2025, the closing day of the 30th edition of the Conference of the Parties (COP) took place, the yearly gathering of United Nations member states to negotiate international climate agreements and assess global progress toward emissions reduction. This year, the event was held in Belém, Brazil, a port city of fewer than 1.5 million people, widely known as a gateway to Brazil's lower Amazon region. First convened in 1992, UN Climate Change Conferences (or COPs) are an international multilateral decision-making forum on climate change involving 198 "Parties" (197 countries, nearly all of them, depending on definitions of country, and the European Union). Their purpose is to assess global efforts toward the central Paris Agreement aim of limiting global warming to as close as possible to 1.5 °C above pre-industrial levels. The event brings together leaders and negotiators from member states, business figures, young people, climate scientists, Indigenous Peoples, and civil society around issues considered essential to that climate goal. This year, COP30 was marked by strong criticism of its ties to the fossil fuel industry, descriptions of agreements as fragile and insubstantial, and the struggle to move climate finance "from pledge to lifeline."
Architectural space has long been framed by permanence: rooms for fixed functions, facades that clearly define where exterior ends and interior begins. Yet contemporary life is defined by overlap and transition: between work and living, interior and exterior, privacy and community. Spatial needs evolve continually, demanding architecture that can respond, adapt, and remain relevant over time.
In this context, adaptability has emerged not only as a design ambition but as a sustainable necessity. Buildings that adjust to shifting uses, evolving climates, or new forms of living extend their lifespan and reduce the need for demolition or extensive retrofits. Flexibility becomes a measure of resilience, allowing structures to remain vital across decades. But how can architecture respond to the evolving ways we inhabit and experience space?
Cities bring together the best and worst of the human condition. They concentrate opportunities for work, social networks, and cultural production, but they also expose deep social inequalities. Among the many forms of urban exclusion are limited access to transportation, housing, leisure, or safety issues. One form that is rarely discussed is thermal inequality. In lower-income neighborhoods, where there are fewer trees, parks, and permeable surfaces, heat accumulates and thermal discomfort dominates, resulting in higher energy consumption and health risks. As concern about the climate crisis grows, this discussion becomes more urgent: extreme heat is no longer just a climatic phenomenon but also a spatial expression of inequality.
The VELUX Group is launching the next step in its Action Leadership agenda as an experiment to explore how existing buildings can better serve both people and planet. The experiment builds on decades of demonstration projects and research into healthy buildings, including Living Places, which achieved an ultra-low carbon footprint and first-class indoor climate in an affordable and accessible way. The next step shifts focus towards existing buildings, from new build to renovation—named Re:Living.
Re:Living is a forward-thinking experiment to reimagine renovation to be more than a technical upgrade, and instead as a holistic opportunity to improve human well-being, support biodiversity, and reduce environmental impact. It's part of VELUX's long-term commitment to lead the building industry toward healthier, more sustainable practices, driven by a belief that simply reducing harm is no longer enough.
Architectural professionals recognize how exterior design choices influence both perception and performance. A canopy is more than a functional overhang — it is a visual statement, a layer of environmental control, and a reflection of the project's overall design vision.
Among available materials, custom aluminum canopies have become a preferred choice in modern architecture for their resilience, adaptability, and sleek aesthetics. The following outlines their primary advantages.
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.

Offering a path toward resilience and food security in the alluvial plains of Lake Titicaca, the Waru Waru agricultural fields are spread across the Peruvian highlands and constitute an ancient agricultural system. Connecting an ancestral legacy with modern concerns about water and food security, climate resilience, and sustainable land management, these agricultural systems open the debate about efficient water management and the importance of agricultural biodiversity. At the same time, they are part of the sense of identity and pride of the local Aymara community, consolidating cultural knowledge that is passed down and preserved across generations.
Cities today are being reimagined as living, evolving organisms, combining digital intelligence, ecological systems, and new materials to shape radical futures. At Carlo Ratti's "Intelligens. Natural. Artificial. Collective." biennial, over 750 participants challenge established boundaries between architecture, landscape, and technology. Several conceptual projects showcased in the main exhibition challenge conventional boundaries between architecture, landscape, and technology. From bio-adaptive urban systems and Martian water-based settlements to immersive symphonies of satellite data, these works collectively envision new models for cohabitation, resilience, and planetary awareness.
This month's Unbuilt selection presents six speculative projects, presented as part of the 2025 Venice Architecture Biennale exhibition, as provocations for rethinking the future of cities and human settlement. While some proposals transform architecture into self-sustaining, living infrastructures, others explore how data and sensory interfaces can redefine our relationship with natural and urban environments. Together, they offer a cross-section of how architects and designers are using unbuilt work to imagine new possibilities for life on Earth and beyond.
Mountainous and high-altitude regions are considered to be among the most fragile ecosystems on Earth. From melting glaciers to land erosion, these environments face mounting threats from climate change, making it imperative to reimagine how architecture and its supporting infrastructure are designed for such places.
From the 1930s to the 1990s, Burle Marx's work anticipated many of today's concerns about sustainability and urban well-being. Long before terms like "sustainable design" or "green infrastructure" became commonplace, Burle Marx was already advocating for the use of native plants, recognizing their role in creating self-sustaining ecosystems that required minimal intervention. His projects often transformed neglected urban areas into vibrant, ecologically balanced spaces that not only improved the environment but also enhanced the quality of life for city dwellers.
Due to climate change, heat waves are becoming increasingly frequent and intense, and they present a critical challenge for the design of urban spaces. Elevated temperatures exacerbate public health issues, increase energy consumption, and diminish cities' overall quality of life. Urban design must adopt strategies that promote resilience to mitigate these effects rather than merely replicating traditional formats that do not address the thermal stress experienced by many.
For quite some time, we have recognized the positive effects of urban green spaces, interaction with nature, water, and soil, and the associated health and well-being benefits for residents living next to parks. The significance of this matter has been further underscored, particularly in the aftermath of the panic induced by the Covid-19 pandemic. However, the present moment once again highlights the influence of our urban models on modern life, now grappling with unprecedented extreme temperatures.

The world has changed, and accepting this fact is no longer a matter of choice but survival. Our rainfall patterns, periods of drought, average temperatures, sea levels—everything is in constant flux. The denialist stance of many countries, including Brazil, has led to catastrophic situations like the one we are facing now.
The floods that devastated the southern region of the country in recent days cannot be considered isolated incidents. Due to global warming, climate events like this will become increasingly frequent. In other words, unfortunately, we cannot prevent them from happening, but we can—and must—make our cities more resilient to these situations.
CityMakers, The Global Community of Architects Who Learn from Exemplary Cities and Their Makers, is working with Archdaily to publish a series of articles about Barcelona, Medellin, and Rotterdam. The authors are the architects, urban planners, and/or strategists behind the projects that have transformed these three cities and are studied in the "Schools of Cities" and "Documentary Courses" made by CityMakers. On this occasion, Victor Restrepo, Coordinator of CityMakers in Medellin, presents his article "Medellin: A Case Study".
Medellín stands as an inspiring example for many cities worldwide. It is a city that transitioned from deep collective fear to hopeful enthusiasm for urban and social life characterized by quality and coexistence. The city's crisis has always been associated with violence and drug trafficking. However, this crisis is more structural and profound, it responds to many more factors, some of which are associated with the accelerated growth of its population, as in many Latin American cities.

Zaha Hadid Architects have unveiled a large-scale project for the redevelopment of the Al Khuwair waterfront in downtown Muscat, the capital of Oman. The $1.3bn project covers an area of 3.3 million square meters. It aims to revitalize the area through sustainability-led design principles to accommodate the expected population growth, which is expected to almost double by 2040. The plans are developed in collaboration with Buro Happold to incorporate and transform the existing buildings on site, introduce coastal and climate resilience measures, and create an efficient transit-oriented infrastructure.
In the rapidly evolving landscape of the 21st century, cities have emerged as models of innovation in terms of sustainable development goals. Cities creatively address pressing urban challenges, including density, transportation, housing, and resilience. They hold the potential to pioneer a comprehensive climate agenda, serving as laboratories for sustainable initiatives, cross-sectoral innovations and community-oriented strategies. Cities act as catalysts for revolutions, implementing impactful solutions that can be applied worldwide.
MVRDV and Orange Architects collaborate on the NUVO project, a new mixed-use complex to be built in Ukraine’s capital, the team of architects has revealed their design for three of the buildings that will become part of NOVO. Commissioned by Kovalska, the project is now restarting after work was put on hold due to the active conflict in Ukraine. The two firms are collaborating to refine the master plan initiated by APA Wojcehowski Architects.
The Türkiye Design Council (TDC) has gathered 13 design practices, including Foster + Partners and Bjarke Ingels Group, to contribute to the revitalization of the historic province of Hatay, an area severely damaged by the 7.8 magnitude earthquake in February this year. Foster + Partners has been selected to lead the design and planning of the new master plan for the city of Antakya, known to antiquity as Antioch, while several other offices including Turkish practices DB Architects and KEYM (Urban Renewal Center) will work together to create a vision for the rebuilding of the city. The master plan is expected to be revealed in its entirety in 2024.
As the world grapples with the effects of climate change, natural disasters like flooding, and the spread of incontrollable wildfires are increasingly threatening cities and inhabitants. While architecture and urban planning cannot prevent these occurrences, they still possess strategies to minimize the damage associated with these events and help protect the citizens. Unfortunate events over the course of last year, like the earthquake that hit central Turkey and north-west Syria this February or the more recent earthquake in western Afghanistan, the flooding and dam failures in Libya, and the wildfires that devastated the city of Lahaina, Hawaii, demonstrate the urgency of implementing preventative and mitigation measures in addition to creating procedures for emergency intervention. This article explores the strategies and resources available to architects and urban planners to address these challenges in three types of natural disasters: flooding, wildfires, and earthquakes.
