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.

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.
