CO-BLOCKS is an innovative response to the challenges of collective housing in Rome. Located along the Tiber River in the Ostiense neighborhood, it integrates residential spaces with various community functions. The design emphasizes sustainability and the importance of social interaction, aiming to create a lively living environment that fosters connections among residents.

Design Principles

The project is built around five core principles: sustainability, context, overt functionality, mixed-use integration, and intelligent connectivity. The emphasis on sustainability encourages a harmonious relationship between nature and the built environment. Contextual design ensures that the development respects the historical and cultural elements of Rome while adapting to modern requirements.

Spatial Arrangement

The layout supports various activities grouped into categories such as rest, work, market, make, learn, consume, and grow. This arrangement promotes diverse interactions among residents, helping to create a collaborative atmosphere. By blending different uses, the design maximizes space, making it possible for multiple functions to coexist in a cohesive manner that enhances community living.

Community Integration

The CO-BLOCKS project is situated in a vibrant area that includes a diverse population. The design aims to enhance the community by thoughtfully distributing public spaces and amenities. Accessibility is a key focus, ensuring that all areas are within easy reach, which encourages residents to engage with each other and their surroundings.

The approach ensures that the built environment fits comfortably within its context, enhancing the local character. Notable features include the blending of private and public spaces, which invites residents to interact within their environment, fostering a strong sense of community.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
