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.
The housing crisis, the need for effective land management policies, and the growing demand for housing aid are global challenges, and Spain has taken significant steps to address these issues in recent years. While this effort is closely tied to rehabilitating obsolete buildings, it also tackles the challenges of densification and gentrification. These factors have prompted the exploration of new housing models and ways of living, leading to the development of affordable residential buildings designed to accommodate large numbers of inhabitants while maintaining high-quality living standards.
Sustainability has been a central theme in architectural discussions for years, encompassing not only the profession’s role in combating climate change and transitioning to low-carbon economies but also preserving cultural heritage and celebrating vernacular traditions. In 2024, a wave of projects and studies stood out for their innovative use of natural materials, particularly in the Global South. These initiatives skillfully blend creativity and technology with renewable resources, demonstrating how architecture can deliver high-quality spaces that align with contemporary demands for sustainability and environmental responsibility.
The concept of low-tech architecture recognizes the impact of carbon-intensive technologies and building practices and proposes an alternative: a rediscovery of practical, rational, locally adapted solutions that count on smart design strategies instead of energy-intensive devices to ensure a safe, comfortable living environment. Far from being a regressive approach, the term remains open to innovations but seeks to rebalance the industry's reliance on mechanization. It thus favors an architecture of fewer components, minimized dependence on high-tech solutions, and a preference for low-embodied carbon materials.
In 2024, a diverse range of topics have been comprehensively explored, some focusing specifically on architectural details and construction systems. These articles provide valuable insights into architecture's often-overlooked technical and functional aspects. By shifting attention away from aesthetics, materials, and spatial massing, they reveal the importance of intricate details and the construction systems underpinning contemporary projects' larger architectural vision.
Executing these seemingly small elements is crucial in shaping how architecture is perceived and experienced. Specifying and drawing a thoughtfully designed detail is not dissimilar to determining the correct screw in building a car—its thread count, material, and length—can dramatically influence not only the success of an architectural design but also the quality of the human experience it fosters. Such details, while often dismissed as mundane and may not be the most recognizable features of stellar projects, profoundly impact the cohesiveness and functionality of architectural projects.

It highlights how the practice reimagines and reinterprets traditional building methods, translating them into contemporary contexts while emphasizing a collective and collaborative approach to architecture.
The 29th United Nations Climate Change Conference (COP29) took place in Baku, Azerbaijan, from November 10 to November 24, 2024, amid a backdrop of escalating climate challenges. For cities, the epicenters of population growth, economic activity, and climate vulnerability, the outcomes of COP29 are particularly significant. As urban areas contribute over 70% of global carbon emissions and housing more than half of the world's population, their consideration is pivotal in shaping global responses to the current crisis. In fact, cities are on the frontlines of the crisis, facing record-breaking heatwaves, catastrophic floods, and increasing economic losses from extreme weather events. In 2024 alone, urban areas worldwide experienced devastating climate impacts: flooding displaced millions in Africa, droughts crippled urban economies in South America, and storms caused widespread destruction in North America and Europe. The outcomes of COP29 directly affect urban planning, architecture, and sustainability efforts. From commitments to climate finance and carbon markets to renewable energy and resilience-building, the summit's decisions provide a roadmap for transforming cities into hubs of climate innovation and adaptation. Below are the key takeaways from COP29 for the built environment and urban spaces.
Lydia Kallipoliti is a recognized architect, author, and educator whose pioneering research has transformed the way architecture engages with the pressing challenges of sustainability, technology, and environmental politics. As an Associate Professor at Columbia University's Graduate School of Architecture, Planning, and Preservation (GSAPP), Kallipoliti's approach to architectural education encourages students to confront critical issues such as waste, reuse, and closed-loop systems. Her pedagogical philosophy empowers students to see design not only as an aesthetic or functional pursuit but as a powerful tool for addressing global ecological crises, urging them to think systemically and creatively about the future of the built environment.
In addition to her role in academia, Kallipoliti has authored influential works such as The Architecture of Closed Worlds and Histories of Ecological Design: an Unfinished Cyclopedia, which delve deeply into the relationship between architecture and environmental politics. Her research and writings have sparked discourse on methods for architects to reconsider traditional design paradigms and embrace sustainability as a core tenet of architectural practice.
The 29th Conference of the Parties to the UN Framework Convention on Climate Change (COP29) takes place between the 11th and 22nd of November in Baku, Azerbaijan. The event proposes a global gathering of business leaders, governments, and civil society with the aim of taking effective measures to limit global warming to 1.5°C above pre-industrial levels. As the construction industry is responsible for approximately 37% of global emissions, the conference is of particular interest to architects, urban planners, and researchers in this field.
By now, most people in the construction industry know that addressing the carbon emissions that come from the built environment is key to solving the climate challenge. Yet, knowing where to start can be a challenge for many professionals. That's why education and upskilling across the value chain—from architects to urban planners, and real estate developers to engineers—are essential to fostering sustainable construction practices.
Architectural grafting, a concept recently popularized by Jeanne Gang inThe Art of Architectural Grafting, presents a transformative approach to urban regeneration and sustainability. Drawing inspiration from botanical and horticultural practices — where new growth is added to existing plants for enhanced resilience — this architectural method integrates new structures with existing ones, allowing them to coexist and adapt. Rather than pursuing demolition, grafting prioritizes adaptation, extending the life of buildings while safeguarding their cultural and historical significance.
While Studio Gang has played a pivotal role in advancing this method, architectural grafting embodies a broader principle that architects have long used to enhance sustainability, conserve resources, and honor heritage. Across scales — from individual buildings to urban landscapes —grafting reshapes the relationship between past and present, adapting existing structures for contemporary needs while addressing environmental demands. By reimagining historic buildings for modern use, this approach fosters a sustainable evolution of cityscapes.
Marie Combette and Daniel Moreno Flores founded La Cabina de la Curiosidad in 2019, a studio focused on architecture and territory based in Quito, Ecuador. Their architectural approach is based on extensive fieldwork, with an urban and territorial perspective that prioritizes the use of available resources, water management, and recycling. They use drawing and mapping as essential tools to materialize their ideas and transform them into spaces. The name of the studio evokes a "trunk" turned into a cabin full of curiosities that invite exploration of various possibilities. This trunk is nourished by everyday experiences, derived from simple interactions with the city or the environment, which triggers a creative process continually fed by experimentation and daily discovery, unafraid of the unknown.
