Across Europe's major tourist cities, housing affordability has increasingly emerged as one of the most pressing urban challenges, prompting governments to reassess the role of short-term rentals within residential neighborhoods. In Barcelona, Mayor Jaume Collboni recently announced plans to phase out tourist short-term rentals entirely by 2028, framing the decision as part of a broader effort to protect residents' right to remain in the city. The announcement coincides with a €64 million fine imposed by the Spanish government on Airbnb for advertising unlicensed properties, placing Spain at the center of an intensifying debate over how tourism-driven accommodation models intersect with housing access, inequality, and urban stability.

As cultural institutions advanced major preservation projects and new demographic data reframed understandings of urban growth, this week's architectural discussions centred on how cities and museums adapt to evolving social, environmental, and infrastructural conditions. Efforts to safeguard modern heritage, developments in long-term urban planning, and reflections on architectural legacy intersect with global observances such as the International Day of Persons with Disabilities, highlighting the ongoing need for more inclusive and accessible environments within the built landscape.

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.

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.


As Athens hosts The Architect Show (TAS) 2024, the event brings together global and local voices to highlight the latest innovations in architecture and design. Against this backdrop, the city's evolving urban narrative is exemplified by The Ellinikon, Europe's largest urban regeneration project. Encompassing 6.2 million square meters, this €8 billion development has already attracted globally renowned architects such as Bjarke Ingels Group (BIG), Kengo Kuma, Foster + Partners, and Aedas. Together, they are shaping the smart city that integrates sustainability, connectivity, and community-focused design into the heart of Athens.

Eastern and Southern Europe is enduring a severe heatwave, with temperatures reaching over 40 degrees Celsius in many countries including Greece, Croatia, Macedonia, and Romania. Driven by hot air from North Africa, this prolonged heatwave has raised significant threats for residents and has strained the cities’ mechanisms for protection and climate mitigation. As the heatwaves expose the vulnerabilities of urban infrastructures, cities across Europe are striving to implement measures to address these challenges.
