Residential Bridge Covered in Thatch and Mud Scales in Karjat, India
Karjat, India A Sustainable Residential Bridge spans a deep valley, connecting two parcels of land separated by a thirty meter wide water channel. The project combines architecture with locally sourced sustainable materials. Its steel structure is clad in a mixture of thatch and mud, reflecting innovation in residential bridge design and environmental integration. The Sustainable Residential Bridge offers a unique living experience inspired by nature. It sets a clear precedent for sustainable design in rural contexts.
Site and Engineering Challenges
The residential bridge is situated on a rugged terrain, requiring careful clearance above the water channel to allow equipment passage beneath. Limited access to construction materials added complexity, encouraging the use of locally available resources instead of relying on distant supplies.
Design Concept and Architectural Approach
The design of this Sustainable Residential Bridge links the two plots and uses the elevated site to create an extended living space above the valley. The structure rests on four sturdy supports. It is covered with a hyperbolic paraboloid surface, clad in a blend of local thatch and mud. This cladding evokes the scale pattern of a pangolin.
The central span of the Sustainable Residential Bridge houses a long living area beneath a large oculus. This allows natural light and airflow into the space. The ends of the bridge contain sleeping units. The kitchen and dining area occupy a glazed volume overlooking a triangular swimming pool and nearby forest. This design reinforces the bridge’s seamless connection between interior and exterior spaces.
Materials and Sustainability
The project relies on local mud and thatch as primary materials to minimize environmental impact, providing natural insulation and structural durability. Mud offers compressive strength to stabilize the structure and protect the thatch from pests, while the thatch forms a sustainable exterior layer with effective thermal performance.
This approach highlights the value of traditional craftsmanship reinterpreted in a contemporary context, preserving material sustainability while adapting to practical site constraints.
Interior Design and Environmental Integration
Inside the bridge, exposed mud surfaces form cocoon like spaces, revealing the imprint of the underlying steel framework. Semi transparent screens divide the interiors, and hammock like areas provide informal seating adjacent to the living space, reflecting a philosophy of integrating nature and comfort within the home.
Architectural Analysis
The project demonstrates an innovative residential bridge typology, balancing aesthetic qualities with structural functionality. The curved, mud and thatch surface showcases a deep architectural understanding of environmental and functional challenges, emphasizing sustainability and interaction with nature. This design illustrates how architecture can serve as a tool to document local materials and landscapes while maintaining comfortable and efficient living conditions.

✦ ArchUp Editorial Insight
The residential bridge stretches over a deep valley, clad in a curved surface of local thatch and mud, evoking the scales of a pangolin in both texture and form. A central oculus introduces natural light and ventilation, while living units, kitchen, and communal spaces are carefully arranged to create fluidity between interior and exterior. The lightweight steel framework beneath the organic cladding demonstrates a balance of structural strength and natural softness. Critically, the project shows how local materials and inventive techniques can overcome challenging site constraints, though future thatch maintenance may pose some concerns. Its overall value lies in documenting the interplay of architecture and environment sustainably and creatively.
