AmphiNest: Kerala floods inspire amphibious homes rising with water
Two Indian innovators developed AmphiNest, an amphibious house that rises with floodwaters to stay above water. After a 200 sq ft prototype funded privately, the project received government support for two additional homes, aiming to flood resilience in Kerala.
Key takeaways
- Two innovators developed a housing concept that rises with floodwaters to stay dry during floods.
- A 200 sq ft prototype was built with personal savings and features a buoyant foundation and guide pillars.
- The first working prototype was completed in 2021, and Kerala government support funded two additional homes.
What Happened
In response to the destruction caused by Kerala’s 2018 floods, Nanma Gireesh and Ben K George launched NestAbide to create housing that adapts to rising water. Their concept, called AmphiNest, sits on a conventional ground base but lifts as flood levels rise, aided by a Concrete Buoyant Foundation and four Guide Pillars that prevent drift. A 200 sq ft prototype was built with about Rs 3 lakh of the founders’ own savings. During the prototype phase, the structure reportedly rose in height as floodwaters rose and remained in place and secure. After completing the first working prototype in 2021, NestAbide expanded to two more amphibious homes with government support from Kerala.
The technology is presented as not limited to new builds; NestAbide claims existing homes can be made flood-resilient using the same approach.
Why It Matters
The project addresses a recurring hazard in flood-prone areas by altering how a house interacts with floodwater, potentially reducing damage and displacement. The involvement of the Kerala government in extending the program suggests a pathway for broader adoption if the design proves scalable and cost-effective.
Background
The concept emerged after severe floods in Kerala in 2018, which prompted the developers to explore homes that could survive inundation by rising with water rather than being submerged. They pursued a practical prototype funded through personal savings and subsequently secured public-sector support for additional homes.
Key Facts
- Inventors: Nanma Gireesh and Ben K George
- Project name: AmphiNest, developed by NestAbide
- Prototype size: 200 square feet
- Initial private investment: approximately Rs 3 lakh
- Key components: Concrete Buoyant Foundation and four Guide Pillars
- Prototype outcome: rose with floodwaters during the prototype phase
- Milestone: first working prototype completed in 2021
- Government role: support from Kerala government for two additional amphibious homes
- Application scope: potential to adapt existing homes to be flood-resilient using the same technology
What Happens Next
The project plans to continue building amphibious homes, with two further units supported by the Kerala government. There is an explicit aim to expand the technology beyond new constructions to retrofit existing houses so they can rise with floodwaters in a flood-prone region.
