Suspended beneath the urban infrastructure, Microhomes equipped with bokashi compost systems create a sustainable living environment on the Dongshuimen Bridge, fostering community interaction while redefining the role of transportation spaces.
5 key facts about this project
01
Microhomes are integrated within a reinforced steel cable system beneath the bridge.
02
Sustainable energy is generated through a combination of wind and solar power.
03
Rainwater and Yangtze River resources are utilized for water supply.
04
Each unit features a bokashi compost system for efficient waste management.
05
Flexible living spaces include foldable furniture and hydroponic gardens.

The project at Dongshuimen Bridge in Chongqing, China, focuses on rethinking the purpose of a traditional arterial bridge. It integrates living spaces beneath the bridge, creating a multifunctional area that promotes both transportation and community interaction. This design moves beyond merely being a passageway and aims to enrich urban life by combining infrastructure with residential elements.

Architectural Concept and Integration

The concept emphasizes the connection between infrastructure and urban living. By using modular container homes, the design challenges the bridge’s limited role as just a transit point. Instead, it envisions the bridge as a space for people to live, interact, and engage with their surroundings. This approach creates a lively atmosphere where movement and habitation coexist.

Structural Design and Sustainability

Microhome units are suspended within a reinforced cable system beneath the bridge. This clever use of space helps maintain the stability of the bridge while maximizing its utility. Each unit operates on an off-grid basis, generating its own electricity using wind and solar energy. This design reduces dependence on traditional power sources, aligning with current trends towards more sustainable living.

Resource Management Systems

Water management is an important part of the design. Rainwater collection systems work alongside the use of the Yangtze River for water supply. Each Microhome includes a bokashi compost system and greywater recycling fixtures. These systems promote efficient resource use and support a self-sufficient living environment, emphasizing environmental responsibility.

Design Features and Adaptability

The design includes features that enhance livability. Foldable furniture and hydroponic gardens make the Microhome units flexible and functional. These elements allow the interiors to adapt to varying needs, encouraging residents to personalize their spaces. This adaptability fosters interactions and creates a sense of community among residents, enhancing the bridge's aim to be more than just a thoroughfare.

The integration of living spaces into the bridge highlights a new way to think about infrastructure. By blending the roles of transportation and habitation, the project creates a setting where urban life can thrive. Innovative features and careful resource management work together to establish an environment that supports both individual needs and community, making the bridge a lively part of the urban landscape.

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.
