Circuit Board Homes offer a thoughtful solution to the affordability issues faced by families in Rome. Located along the Tiber River, the project aims to create a community-oriented living environment. It emphasizes the importance of connection among residents while addressing the practical aspects of urban housing. The design explores how shared spaces can enrich daily life and strengthen social bonds.

Design Concept

The core of the design is a fixed floor plate system that supports various layouts and personalization. Inspired by a computer circuit board, the arrangement fosters connectivity among residents. Central shared areas, such as living rooms, open kitchens, and dining spaces, encourage interaction. At the same time, private bedrooms and bathrooms provide necessary personal space, balancing community and privacy.

Community Structure

The project includes two sizes of communities, each tailored to fit different family needs and local contexts. Residents can expand their living spaces either horizontally or vertically, utilizing an interlocking stud and tube system for stability. This approach allows the design to be adaptable in different parts of the city, including the potential for placement over water.

Material Utilization

Precast concrete is used for the fixed floor plates and standard components, facilitating efficient construction methods. This material choice simplifies the manufacturing process and speeds up assembly on-site. By opting for precast concrete, the design aligns with current building practices while ensuring long-lasting structures.

Design Details

Roof-level exposed studs add features like modular planters or decking systems. These elements enhance the outdoor experience for residents, providing spaces for recreation and relaxation. The careful integration of shared and private areas creates a cohesive environment where community life can thrive in the heart of Rome.

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.
