Casa Collegare is located in Rome and aims to tackle the issue of affordable housing in the city. The design emphasizes maximizing space within typical midblock lots while providing a functional living environment for young working professionals. The layout features interlocking L-shaped living units, creating a balance between individual privacy and communal interaction.

Design Layout

The design includes two L-shaped living units per floor, arranged to optimize the use of space. Each unit is divided into three areas: a private bedroom for restful living, a transition zone that incorporates the kitchen and laundry facilities, and a communal living and dining area that opens onto a balcony. This arrangement encourages both personal time and interaction among residents, catering to modern living needs.

Central Circulation

A central circulation core grants access to all living units, making movement through the building straightforward and intuitive. The mirrored interlocking arrangement on alternating floors provides a visual connection and promotes community among residents. This design allows for casual encounters in shared spaces, enhancing social ties within the building.

Facade and Materials

The facade is designed to highlight the difference between private and public areas. Solid brick walls protect the private bedroom sections, while clear floor-to-ceiling glass is used in the living areas to bring in natural light and connect the indoors with the outside. Delicate metal railings in front of the balconies ensure safety without blocking views, allowing for an open and airy feel.

Ground Floor Amenities

On the ground floor, communal facilities are available, including a reception area, mailbox room, and a social/study lounge. Retail spaces and a cafeteria address the daily needs of residents, making the building more than just a place to live. This design choice promotes togetherness and enhances the experience of living in an urban environment.

The combination of solid walls and open spaces fosters a dynamic connection to the outside world. Natural light flows into the interiors, providing a warm and inviting atmosphere for residents.

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.
