Biodiversity, defined by the World Wide Fund for Nature (WWF) as the different kinds of life found in an area, is in a state of crisis all across the world, with declines in the numbers of organisms and many species declared as at risk of extinction. All types are affected, from plants and fungi to large mammals, and there is a clear link to human activity being the cause. Although farming methods and climate change due to greenhouse gases play a major role, cities and buildings can play a small but important role in countering this decline.
Across diverse climates and landscapes, architects are reimagining the home as a place deeply rooted in its surroundings, where architecture and environment work together to nurture well-being. This curated selection of unbuilt residences, submitted by the ArchDaily community, are conceived as sanctuaries, offering respite from the pace of urban life and drawing on the restorative qualities of greenery, water, and open air. Nature is utilized as an active presence, shaping courtyards, guiding circulation, and influencing the choice of materials and colors.
Seeking to create a fluid dialogue between architecture and its surrounding landscape, the study of topography embodies an awareness and exploration of the use of materials, self-sufficient strategies, low-maintenance solutions, and landscape designs that integrate into the natural environment and minimize the environmental impact of projects. Beyond recording variations in elevation, sun orientation, prevailing winds, or drainage slopes of the terrain, several architects in Argentina demonstrate a strong interest in developing architectural solutions capable of adapting to natural geographies and restoring the bond between nature and the human being.
In early 2025, photographer Paul Clemence documented Kö-Bogen II, a commercial and office complex designed by ingenhoven architects in Düsseldorf, Germany. The photo series focuses on the building's signature feature: its vast green façade, considered one of the largest in Europe. Referred to as a "green heart" and an "urban mountain," the building has become a landmark in the city due to its sloping surfaces wrapped in over 30,000 hornbeam plants. For Clemence, this was an unforeseen encounter during his first visit to Düsseldorf, which he describes as an unexpected meeting with a "stunning green pyramid."
In today’s dense, vertical cities, terraces—often overlooked as mere technical rooftops—are emerging as key spaces for reconnecting with nature, expanding residential functions, and offering moments of collective relief. Particularly in single-family homes located in compact urban areas, these elevated surfaces represent valuable opportunities to increase usable living space without occupying more land. By lifting daily life above street level, terraces open new ways of inhabiting the city, enabling a range of uses from leisure and contemplation to food production and social gathering. In contexts marked by limited green space and strained infrastructure, they hold the potential to generate what landscape architect Catherine Mosbach calls "additional layers of urbanity." Whether imagined as hanging gardens, gathering spots, edible landscapes, or wellness zones, terraces challenge the idea that the city ends at the top floor—inviting us to see the roof as a new kind of ground.
As cities grow and available land becomes more limited, high-rise architecture plays an important role in addressing urban density while shaping new ways of living and working. Tall buildings are evolving beyond their traditional functions to integrate environmental strategies, enhance public engagement, and contribute to the urban fabric. Architects are exploring new materials, energy-efficient technologies, and spatial configurations that make towers more adaptable to their surroundings. Some projects incorporate green spaces and shared amenities to create a stronger connection between the built environment and its users, while others introduce innovative construction techniques to improve sustainability and efficiency.
Among this selection of projects submitted by the ArchDaily community, The Residences at 1428 Brickell by Arquitectonica in Miami, United States introduces a solar-powered facade that contributes to the building's energy needs. In Dubai, UAE, AVA by SOMA creates a transition from the city into a more enclosed, water-defined environment with a focus on luxury living. In Bangkok, Thailand, HAS Design and Research proposes the Bangkok Civic Center Tower as a new type of public space, combining green landscapes with mirrored surfaces to connect the city with nature. These projects reflect different approaches to vertical architecture and highlight how designers are responding to the challenges and opportunities of dense urban environments.
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.

Snøhetta has announced a project to rebuild the Refuge de Barroude, a mountain refuge located in a UNESCO World Heritage site in the Pyrenees Mountain range of France. The old building, destroyed in an accidental fire ten years ago, is set to be revived as a stop-off point for hikers on the Haute Route des Pyrénées and as a support center for the staff of the National Park. The next phase of the project is due to begin in 2025.
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.
