The world's most visited architecture platform

Terraco, a global leader in Exterior Insulation Finishing Systems, has demonstrated through independent studies that when planning building renovations, it is essential to adopt a deep retrofit strategy that includes energy-efficient measures, such as thermal insulation of external walls and roofs.

The studies show that cooling energy use in buildings can be reduced by up to 47% annually in Middle Eastern and South Asian climates, directly as a result of installing the combined Terraco EIFS and Roof Insulation Finishing Systems, compared to leaving external walls and roofs uninsulated.

Greece's built environment is shaped by the coexistence of multiple architectural layers, where historic structures, modern interventions, and evolving urban systems intersect. Classical landmarks and their surrounding urban fabrics continue to inform the spatial character of cities, while postwar developments, infrastructural upgrades, and contemporary projects add new dimensions to the country's architectural landscape. This continuity between past and present provides the foundation for current design approaches, which increasingly focus on balancing heritage, environmental considerations, and contemporary urban needs.

UNS has revealed images of SeoulOne, a master plan designed for Hyundai Development Company (HDC) in Seoul, South Korea, intended as a new model for multigenerational living. The project, already under construction on a brownfield site in the northeast of the city, reimagines an existing industrial site and railway area as a 405,000 m² car-free neighborhood for a multigenerational community. A never-sleeping, green master plan for Seoul, SeoulOne is envisioned as a mixed-use mini-city where all essential services for people of all ages are available within a 10-minute walk. The design includes 24/7 residential towers, retail spaces, offices, a hotel, sports facilities, daycare centers, senior living facilities, and a medical center, offering permanent services within walking distance. More than 30% of the site is dedicated to vegetation, including pocket parks, roof gardens, water gardens, and a forest walk, creating a year-round green village.

Collective housing remains one of the most active areas for unbuilt architectural exploration, revealing how architects are rethinking domestic life, density, and shared living across different cultural and environmental contexts. In this curated Unbuilt edition, submitted by the ArchDaily community, the selected proposals investigate new forms of dwelling that span mobile units, vertical developments, adaptive reuse, and landscape-driven residential clusters. Rather than treating housing as a purely functional container, these projects position it as a social and spatial framework that shapes everyday life, community ties, and long-term urban resilience.

Across varied geographies, from Tirana and Athens to Monterrey, Chaloos, Roatán, Bhola, and the DRC, these proposals explore multiple approaches to collective living: transforming industrial shells into residential structures, extending existing masterplans through landscape integration, reimagining verticality in dense urban centers, and developing modular prototypes that can adapt to changing climates or patterns of mobility. Some projects prioritize ecological strategies and local materials, while others test new models for accessibility, community well-being, or incremental urban growth. Together, they reflect a broad spectrum of architectural responses to contemporary housing pressures.

Jakarta has become the world's most populous city, according to the World Urbanization Prospects 2025 released by the United Nations Department of Economic and Social Affairs (UN DESA). Using an updated and harmonized method for defining urban areas, the report estimates Jakarta's population at nearly 42 million, placing it ahead of Dhaka, which is about 40 million, and Tokyo, 33 million. The revised ranking illustrates how updated measurement criteria and continued demographic growth are reshaping understandings of urban scale in Asia and globally.
