Each monsoon, floods disrupt thousands of families in Bihar, but one innovative floating house designed by engineer Prashant Kumar defies the rising waters, combining sustainability with resilience at an affordable cost.
- House floats as floodwaters rise, preventing damage
- Constructed from locally sourced and recycled materials
- Built for just Rs 6 lakh with plans to reduce costs further
What happened
Every year, monsoon floods threaten homes and communities along the Ganga in Bihar, disrupting lives and cutting off neighborhoods due to rising waters. Witnessing this recurring devastation, engineer and sustainable living advocate Prashant Kumar envisioned a solution that embraces nature rather than fights it. He designed a three-room floating house that rises with the floodwaters, ensuring safety and comfort through seasonal changes.
The house was built using materials sourced from within a 10-kilometre radius to minimize environmental impact. With features like eco-friendly bricks made from cow dung, lime, jaggery, and rice, recycled pipes, solar panels, and a dry composting toilet system, the structure is both environmentally responsible and resilient. All this was achieved at a surprisingly low cost of Rs 6 lakh.
Why it feels good
This innovative home offers more than flood protection—it provides a model for sustainable living in vulnerable areas. By working in harmony with nature, it reduces the carbon footprint and promotes resourcefulness through use of local and recycled materials. The presence of green lawns and solar energy further contributes to a healthy environment and lower living costs for residents.
For communities repeatedly affected by uncertain and extreme weather, the floating house symbolizes hope and resilience. It shows how practical innovation can meet urgent climate challenges, ensuring safety and comfort while preserving the environment. Prashant Kumar’s work invites us to rethink how homes can adapt thoughtfully to changing conditions.
What to enjoy or watch next
Prashant Kumar is taking his vision further by working to reduce the cost of building these floating homes to around Rs 1.5 lakh, aiming to make them accessible to more vulnerable families. His long-term plan is to develop an entire floating village that can withstand floods, remaining selfsufficient and sustainable in the face of climate change.
This project sets an inspiring precedent for flood-prone regions worldwide, blending affordability with climate resilience and sustainability. As climate events become more frequent, these floating communities might become a blueprint for future living that protects both people and the planet.
