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.

The Next House: USA — A Global Call to Reimagine the American Suburb

`
Competition organisers

Buildner is launching The Next House: USA, a global architecture competition that challenges architects, designers, and thinkers to reimagine the American suburban home for the 21st century. For decades, the suburban house has symbolized comfort and stability, but today it often reflects excess, isolation, and environmental strain. This competition asks: how can the American home evolve to address climate urgency, economic pressures, and shifting social values?

Participants are tasked with designing a prototype home of no more than 1,500 sq ft (≈140 m²) for a household of two adults and one child. The design should be compact yet generous, adaptable, sustainable, affordable, and replicable across diverse U.S. contexts. More than a design exercise, the competition aims to spark a conversation about how homes can support healthier, smarter, and more connected communities.

The total prize fund is $20,000 USD. The final registration deadline is May 20, 2026, and winners will be announced on September 22, 2026. The Next House: USA invites architects, students, and visionaries worldwide to redefine what the American home means today—and what it should mean tomorrow.
