Suspended from steel bridges, micro units offer adaptive living spaces that blend urban infrastructure with natural views, redefining how people can inhabit underutilized urban areas.
5 key facts about this project
01
Micro units are directly suspended from existing steel bridges, utilizing the structure for stability.
02
Access pathways connect ground level to the living spaces, promoting community interaction.
03
Each unit is designed for self-sufficiency, minimizing reliance on traditional infrastructure.
04
The project transforms underutilized urban spaces into functional residential areas.
05
Focus on maximizing views enhances the relationship between residents and their environment.

Under the Bridge reinterprets urban living by integrating micro units into existing steel bridge structures, turning often overlooked parts of the city into practical homes. Positioned within underused bridges across North America, the design emphasizes adaptability and a response to current housing needs. It takes advantage of existing infrastructure to promote a thoughtful approach to urban development.

Conceptual Framework

The idea behind the design is to use infrastructure that is usually meant for transportation as spaces for living. This shift challenges the typical practice of expanding into new land, instead focusing on repurposing what is already available in the urban landscape. By placing micro units within the bridge, the design creates a blend of urban life with nature, providing a unique place for people to call home.

Structural Composition

Micro units are suspended from the steel framework of the bridge, using the strong material for support and stability. This method enhances the views residents enjoy while also introducing a lighter look compared to traditional heavy buildings. Residents can access these units through pathways that connect ground-level entries to the spaces below, fostering a sense of community.

Sustainability and Adaptability

A key feature of the design is the self-sufficiency of the micro units. Each unit depends on the bridge's structure for support, reducing the need for extensive groundwork and lowering the environmental footprint. The design allows for reconfiguration in the future, making it responsive to changing needs in urban living. This flexibility is important in today's context, as it supports housing solutions that can grow and change.

Design Details

Inside the micro units, the layout is carefully thought out to maximize light and space. Large windows provide natural light and a clear view of the landscape, encouraging a connection between residents and their environment. This attention to light and space highlights a commitment to integrating living spaces with the natural world around them.

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.
