Suspended Microhomes with Integrated Bokashi Compost Systems Beneath Urban Infrastructure

Project in-detail

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 MICROHOME 10 competition invites participants to submit visionary designs for off-grid, modular microhomes that push the limits of sustainable, small-scale living. Organised by Buildner in partnership with Kingspan and Hapi Homes, this tenth edition sets the challenge of designing a dwelling for two people within a maximum floor area of 25 m², encouraging bold solutions adaptable to any urban or rural location. The competition continues Buildner’s mission to foster innovative approaches to compact, energy-efficient housing that can address pressing global challenges.

This year’s edition offers a generous total prize fund of €100,000, including the Kingspan Award for designs that integrate high-performance Kingspan products and the Hapi Homes Award for a project selected for real-world construction. In addition to cash prizes, the winners gain international exposure through Buildner’s media partnerships, publications, and a dedicated MICROHOME magazine, further amplifying their ideas to the wider architectural community.

Key dates for MICROHOME 10 include the closing date for registration on 25 September 2025, the submission deadline on 29 October 2025 (11:59 p.m. London time), and the announcement of winners on 9 December 2025. These milestones ensure participants have clear timelines to develop and present their concepts, with early registration discounts available to support students and emerging designers worldwide.
