Bridge-Toilet by FMD: A Public Utility That Connects Infrastructure, Culture, and Ecology

Redefining Rural Infrastructure through Architecture

Situated at the entrance of Gaoqiao Village in Yibin, Sichuan, the Bridge-Toilet project by FMD reimagines what a rural public utility can be. This multifunctional structure is not merely a toilet but a pedestrian bridge, a tool storage space, and a sightseeing platform—all seamlessly integrated into the cultural and agricultural fabric of the community. Set within the verdant landscape of the Yichangxing Hundred Mile Green Bamboo Corridor, the project responds to the village’s identity as a model for rural revitalization through bamboo culture.

A Hybrid of Public Utility and Agricultural Support

The Bridge-Toilet is designed as an agricultural-supporting complex, blending sanitary infrastructure with rest areas and storage facilities for farming tools. Unlike conventional rural public toilets that are often overlooked, this structure supports both physiological and practical needs—serving villagers and tourists alike. It emphasizes the integration of appropriate ecological technologies, furthering the sustainability goals of the community.

Site-Specific and Contextual Design

Nestled within farmlands and bounded by roads at varying elevations, the site posed both a challenge and an opportunity. The structure bridges a 4-meter height difference between pathways on either side of the field, acting as a connective spine in the village’s pedestrian circulation system. The building’s folded geometric form emerges from the site’s topography and circulation patterns, symbolizing connection and support.

Architectural Strategy: Folding Forms and Layered Functions

The design strategy employs a three-dimensional folded wall system to create a self-supporting structural frame. On the bridge level, gendered restrooms are arranged in alternating segments along a continuous folding wall—efficiently organizing space while ensuring clear pedestrian flow. The rhythm of solid and void introduces a dynamic spatial experience, creating visual permeability and light play.

The lower level houses a family bathroom, accessible toilet, and agricultural tool storage, making it a multifunctional node in the rural landscape. Access to the rooftop is provided through stairs at multiple elevations, where visitors can enjoy panoramic views from the viewing platform—a thoughtful gesture that enhances the building’s relationship with its surroundings.

Material Expression and Local Craftsmanship

The project champions the use of local materials and labor. The outer facade is constructed from rough bamboo formwork concrete, paying homage to the region’s bamboo heritage. In contrast, the interior surfaces are clad with locally produced green tiles, creating a sensory dichotomy between rugged exteriors and refined interiors. The inclusion of circular porthole windows at varying heights provides interactive, child-friendly moments while illuminating the interiors naturally.

Sustainable Rural Revitalization

Built in collaboration with local craftsmen and bamboo workers, the Bridge-Toilet stands as a testament to how architecture can drive rural development. It’s not just a public amenity—it’s a catalyst for cultural continuity, environmental stewardship, and socio-economic engagement.
