Climate Crisis: The Latest Architecture and News

This curated selection of projects from the 2025 Venice Architecture Biennale explores regeneration as a deliberate, intelligent process rooted in the specific conditions of a place. For decades, the Biennale has been a testing ground for architecture's most urgent ideas, allowing designers, researchers, and institutions to present visions that address evolving environmental, cultural, and social challenges. This year's projects reveal how regeneration, whether of an entire coastal city, a disused industrial site, or a neglected public space, requires more than replacing the old with the new. It calls for a precise reading of existing contexts, the preservation of embedded knowledge, and the careful integration of contemporary needs.

The eight selected works show that regeneration can emerge from multiple starting points: reactivating heritage through adaptive reuse, restoring ecological systems as part of urban planning, developing open and modular strategies for social housing renewal, or layering technological innovation onto historically rooted practices. While the scale of intervention varies, each project demonstrates a sensitivity to what is already there and existing, be it material resources, urban patterns, or cultural memory, and a willingness to work with these assets as catalysts for transformation. Together, they suggest that regeneration must start somewhere, and that its success lies in balancing innovation with the intelligence of what already exists.

In 2020, in the midst of the first wave of lockdowns due to the pandemic, the municipality of Amsterdam announced its strategy for recovering from this crisis by embracing the concept of the “Doughnut Economy.” The model is developed by British economist Kate Raworth and popularized through her book, “Doughnut Economics: Seven Ways to Think Like a 21st-Century Economist”, released in 2017. Here, she argues that the true purpose of economics does not have to equal growth. Instead, the aim is to find a sweet spot, a way to balance the need to provide everyone with what they need to live a good life, a “social foundation” while limiting our impact on the environment, “the environmental ceiling.” With the help of Raworth, Amsterdam has downscaled this approach to the size of a city. The model is now used to inform city-wide strategies and developments in support of this overarching idea: providing a good quality of life for all without putting additional pressure on the planet. Other cities are following this example.

Germany's contribution to the 19th Venice Architecture Biennale 2025 exposes visitors physically and psychologically to the future urban climate: a STRESSTEST that makes the need for immediate action palpable. The exhibition takes a clear stance: climate change is an unstoppable reality, and the measures taken so far are inadequate. It presents a scenario in which climate change manifests globally through rising temperatures, extreme weather, and sea level rise, with its effects directly felt at a local level: urban spaces suffering from heat stress. Curators Nicola Borgmann, Elisabeth Endres, Gabriele G. Kiefer, and Daniele Santucci have designed an exhibition to highlight the impacts of global warming on urban life in an urgent call to action, emphasizing that this reality threatens urban social life, productivity, and the health and survival of citizens.

As climate instability reshapes design priorities, architecture is increasingly drawn into ecological debates not as a spectator but as a participant. Among the concepts gaining traction is rewilding, a practice rooted in the restoration of self-sustaining ecosystems through the reintroduction of biodiversity, the removal of barriers, and the rebalancing of human presence in the landscape. Though often associated with conservation biology, rewilding also opens up new spatial and architectural imaginaries — ones that challenge conventional notions of permanence, authorship, and use.

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.

From Milan's Scalo Farini to downtown Chicago, and from the Tuscan countryside to the UK's retrofit initiatives, recent announcements demonstrate how architecture is evolving in response to climate goals, cultural identity, and urban transformation. Herzog & de Meuron's new headquarters for UniCredit will anchor one of Europe's largest redevelopment sites with a focus on sustainability and workplace innovation, while Gensler's stadium design for Chicago Fire FC aims to redefine the U.S. matchday experience as part of a major waterfront development. In Tuscany, Alvisi Kirimoto's Sapaio Pavilion merges agricultural production with architectural sensitivity, and in the UK, RIBA and The King's Foundation are advancing retrofit as a national agenda. Meanwhile, finalists including MVRDV, Heatherwick Studio, and Mecanoo are advancing in an international competition to create a climate landmark intended to inspire large-scale behavioral change. This edition of Architecture Now brings together diverse yet interconnected efforts to shape how architecture can support long-term ecological, cultural, and civic impact.

Extreme heat is one of climate change's most urgent and rapidly growing consequences, especially in cities. Urban areas are particularly vulnerable because they trap heat in building materials and urban streets, creating dangerous conditions for residents. As temperatures continue to rise and heat waves lengthen, cities are grappling with how to remain livable in the face of this intensifying threat.

Urban green spaces are considered one of the most appropriate and accessible ways to mitigate the effects of rising temperatures in urban environments. As the global climate warms, cities worldwide face more frequent and extreme heat waves, putting their citizens at risk. Many cities are employing strategies for reducing the impact of urban heat islands, which are generated when natural land cover is replaced with surfaces that absorb and retain heat, such as pavements and buildings. This raises the temperature by several degrees compared to the surroundings. Cities have their micro-climate, influenced by this phenomenon combined with a series of often overlooked factors. For a climate strategy to be efficient, all factors need to be taken into consideration.

The main role of architecture is to create structures that protect us from the environment and create spaces that are safe and comfortable for all types of needs and activities. By providing shelter, architecture also shapes the way people interact with their surroundings. Building technologies of the past rarely managed, however, to create a complete separation between us and the outside world.

While impermeability was a desired outcome, the porous building materials available always allowed some water, wind, or outside particles to leak into the interior spaces. In contrast, modern technologies now allow for almost completely impermeable building envelopes, allowing for complete separation between indoors and outdoors, thus relying on engineered systems to regulate temperature, airflow, or humidity. This article explores the differences between these two contrasting approaches, exploring how building facades are equipped to regulate indoor comfort and its environmental impact.

Modernism emerged in the early 20th century as a revolutionary movement that rejected historical styles, prioritizing functionality, innovation, and rationality. Grounded in the promise of industrial progress, architects like Walter Gropius, Le Corbusier, and Ludwig Mies van der Rohe championed using new materials and construction methods, striving for a universal architectural language. Their work introduced radical ideas: open floor plans, expansive glazing for natural light, and pilotis that elevated structures, symbolizing a new architectural era. However, alongside its groundbreaking ideas, modernism's relationship with sustainability has sparked ongoing debates.

While modernist architects sought to address social and economic challenges through affordable housing and efficient design, their reliance on energy-intensive materials like concrete and steel created unintended environmental consequences. The large-scale industrialization celebrated by modernists often disregarded local climates and ecological systems, leading to inefficiencies. Yet, the principles of functionality and adaptability embedded in modernist architecture laid the groundwork for what we now recognize as sustainable practices. From Le Corbusier's rooftop gardens to Frank Lloyd Wright's integration of nature, the seeds of environmentally conscious design were undeniably present, albeit limited in their execution.
