Every architecture student knows what it's like to spend sleepless nights working away, rushing to finalize a project as a deadline looms ahead. Revising every detail, putting the finishing touches and hoping for the best. The pay-off? Seeing the finished project, talking about it with your classmates, and getting to dream about your perfect idea of what a space should look and feel like.
Residential architecture remains one of the most active fields for unbuilt architectural exploration, offering a lens through which architects rethink how domestic space can respond to landscape, climate, and contemporary patterns of living. In this Unbuilt edition, submitted by the ArchDaily community, the selected proposals bring together a range of residential projects that engage with houses, villas, and retreats as sites of withdrawal, mediation, and everyday inhabitation. Rather than treating the home as a fixed or isolated object, these projects approach it as a spatial framework that negotiates exposure, privacy, and connection to place.
Renzo Piano Building Workshop, in collaboration with Betaplan Architects (Athens) and landscape architect Camille Muller (Paris), has broken ground on a new cultural center in Piraeus, the port of Athens. Commissioned by The Dinos and Lia Martinos Foundation (DLMF), the project seeks to establish an international hub connected to similar art centers abroad, open to the local community, students, and visitors, and contributing to the urban and cultural fabric of the Athens metropolitan area. The complex, called KYKLOS, is planned to host contemporary art collections and cultural programming with an international outlook. Initiated in 2023, the project is currently in development, with construction planned to extend through the last quarter of 2028.
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.
Amid countless questions, reflections, and debates about rethinking what a hotel can be, current hotel architecture faces growing complexities that span user experience, environmental responsibility, and the relationship with local context. Contemporary hotel design shows a clear—and increasingly prominent—intention to blend seamlessly and harmoniously with its surroundings, building a sense of identity that responds to local cultures, traditions, and character. The interconnection with nature, along with the reinterpretation of hotels as spaces for engaging with their surroundings, creates a direct relationship that expands their boundaries beyond the history and origins of the many practices that have shaped—and continue to define—their local characteristics and philosophy of life.
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.
Athens stands as a city where the legacy of Antiquity is woven into its modern and vibrant urban landscape. World-renowned landmarks of Ancient Greece like the Acropolis and the Parthenon stand as enduring symbols of classical architecture and the city's storied past. These structures reflect the foundational principles of symmetry and balance that have influenced generations of architects and continue to attract scholars from around the world. Yet, Athens is also a thriving metropolis where contemporary architecture coexists with its historical counterparts. Recent developments, led by international firms and local architects, focus on sustainability and innovation while respecting Athens' rich cultural heritage. This duality—preserving the old while embracing the new—reflects Greece's broader urban aspirations, making Athens a focal point in global architectural discourse. The city's architectural evolution also extends to its contemporary architecture and interior design scene, which is gaining international recognition.
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.
Foster + Partners has developed a master plan for the redevelopment of the former FIX brewery in Thessaloniki, Greece. The proposal, commissioned by Dimand, outlines a mixed-use district that integrates public space, housing, hospitality, and cultural programs. Positioned along the western seafront and within walking distance of the city center, the site serves as a key point of connection between emerging neighborhoods and the waterfront. The project builds on the industrial history of the brewery complex while introducing new spatial configurations intended to support broader urban regeneration efforts across Thessaloniki.
