Post Padma Bridge Vision: An Eco-Economic Framework From Kumarbhog To Louhajang | Bachelors Design Thesis on Regenerative Architecture

Site Context

The region is defined by fertile agricultural land, dispersed rural settlements, and active local bazaars where fishing remains the primary economic activity closely linked with agriculture and informal trade networks. Ferry ghats and connecting roads function as important mobility corridors generating periodic intensities of exchange across the landscape.

Despite productivity, the site faces seasonal flooding, riverbank erosion, and fragmented infrastructure. These processes also sustain soil fertility, aquatic biodiversity, and cultural practices deeply rooted in river life. The analysis reframes this dual condition as an opportunity for resilience and stability.

Half the site is an ecological preservation zone retaining floodplains and vegetation, allowing seasonal water fluctuation. A floodpark with riprap revetment stabilizes the river edge while enabling controlled monsoon flooding, reducing erosion. In dry seasons it becomes a public space, strengthening community river interaction.

The program supports livelihoods through fish and farmer markets and an ice plant, strengthening production and distribution. Supporting uses include composting areas, vendor spaces, eateries, and resting zones, creating income and social exchange. Cultural practices such as festivals, storytelling, weaving, and fish processing are integrated with basic infrastructure, ensuring accessibility and environmental responsibility.

Design Process

The architectural approach is rooted in local construction traditions, particularly the logic of Kather Bari. A modular system is adopted to ensure flexibility and adaptability in response to changing river conditions. Structures use mortise and tenon joinery, avoiding metal fasteners, allowing easy assembly and disassembly. A Wagoya roof truss system enables the relocation of buildings if the river shifts over time.

Materials such as treated timber, jute, and composite tin sheets are selected for their local availability, lightweight properties, and durability in monsoon climates. The use of jute composite introduces a sustainable material innovation grounded in regional resources.

Climatic responsiveness is integrated through adjustable louvered openings for cross ventilation and glare control, along with extended roof overhangs for protection from sun and rain. A double-loaded verandah system works as a transitional buffer that reduces heat gain and encourages shaded social interaction.

Spatial organization follows traditional rural settlement patterns. Built forms are arranged through a sequence of enclosed, semi-open, and open-to-sky spaces. Tree canopies create shade and microclimates, while central courtyards support ventilation and social connectivity. Each structure maintains a direct relationship with the river, reinforcing community identity and ensuring gradual transitions between private, semi-public, and public spaces.

Final Outcome

The project follows a design thinking framework inspired by David Kelley. The process begins with understanding the daily lives of fishermen, farmers, and local vendors. It then identifies key challenges such as erosion, flooding, and economic instability before generating adaptive strategies that integrate ecological resilience with livelihood support.

Although full-scale prototyping is beyond the scope of the academic project, flexibility is embedded within the design. Modular structures and adaptable spaces enable users to modify and evolve the environment over time, making the community an active participant in the design process.

The project redefines the riverfront as a living and evolving system rather than a static boundary. It integrates ecological processes with economic activities and cultural practices to create a balanced and resilient environment.

Instead of offering a fixed solution, the proposal establishes a flexible framework that can adapt to environmental changes and community needs over time. It acknowledges uncertainty as a design opportunity and positions adaptability as a central principle.

This is not a final answer but an adaptive solution for the living process of the river by the people.

Conclusion: Ultimately, the project reimagines the riverfront as a living and adaptive system where ecology, livelihood, and culture coexist through a resilient framework that embraces environmental change, strengthens community identity, and supports long-term sustainability.
