In the devastating floods of 2018 in Kerala, India over 400 individuals misplaced their lives, and 1000’s of homes had been severely broken throughout the state. The calamity led to a number of scorching discussions on bringing in applied sciences or designs that might face up to floods and different pure calamities.
It was across the similar time that Nanma Gireesh from Thiruvananthapuram was engaged on her Grasp’s thesis on ‘amphibious homes’. The flood and the post-flood discussions on flood resistance motivated Nanma and her good friend and classmate Ben Ok George to provide you with an initiative to resolve the most-discussed conundrum.
Thus in 2018, the 2 pals launched their startup, NestAbide, specializing in flood-resistant applied sciences and amphibious development.
Their startup is an interdisciplinary agency engaged on applied sciences which might be used earlier than, throughout and post-flood eventualities. Additionally, it’s the solely agency in India primarily specializing in amphibious housing, resilient and adaptation applied sciences for individuals.
Later in September 2021, they constructed, Amphi Nest, India’s first working prototype of amphibious constructing know-how with a concrete buoyant basis.
Amphi Nest is India’s first working prototype of an amphibious constructing.
What’s amphibious dwelling?
Nanma, who was engaged on her thesis even earlier than the floods, acquired broad appreciation when she introduced her thesis in 2018, post-floods.
“The floods made individuals search for development applied sciences that may fight such pure calamities and it was a scorching dialogue at that time. It was the rationale why I acquired a lot appreciation whereas presenting my thesis,” Nanma tells The Higher India.
“Bringing in applied sciences like amphibious housing is so related in states like Kerala the place pure calamities like floods are actually a yearly phenomenon,” she provides.
Nanma and Ben met throughout their post-graduation in translational engineering from Barton Hill Authorities Engineering Faculty, Thiruvananthapuram, the capital Kerala in India. “We each had been classmates and shared the identical imaginative and prescient of working for a trigger collectively. That’s how we teamed up,” says the 28-year-old.
“It was quite a mission to advertise amphibious dwelling by adapting to reside with the water as an alternative of combating in opposition to it,” says Ben.
The startup was launched in October 2018, unofficially with none revenue or capital funding. They employed a small group and continued their analysis on amphibious homes.
“After post-graduation, we each labored in our school and balanced it with the analysis concurrently. We used our salaries to pay our two group members who had been employed for our analysis. It went on for over a 12 months till we left our jobs in 2019. Quickly after, in October 2019, we formally registered our startup,” he says, including that they continued their analysis work.
When the pandemic hit in 2020, the startup was transformed full-time. “We began doing tasks on flood modelling of rivers to establish when the flood extends when dams open or river floods. This was finished in partnership with a personal firm for Kerala Water Authority,” says Nanma.
Additionally they labored on a global challenge — the Amphibious and Floating constructing analysis challenge that was funded by the Authorities of Canada by the Nationwide Analysis Council of Canada and in affiliation with the College of Waterloo, Ontario. “We had been fortunate to have been a part of the challenge the place we go to work beneath the management of Dr Elizabeth C English, Affiliate Professor, College of Waterloo and Head of Buoyant Basis Undertaking,” she says with a smile.
“Concurrently we had been transferring ahead with our startup’s analysis,” provides Nanma.
Later in 2021, the startup constructed a working prototype of an amphibious constructing at Kuravilangad within the Kottayam district of Kerala. “Amphi Nest was an effort to indicate to the plenty how the amphibious constructing stays on land like all typical house and solely floats when the floodwaters arrive. It was inaugurated by Shri P Prasad, Kerala’s Minister for Agriculture,” says Ben.
“We used our funds to construct it. The prototype pavilion of 200 sq ft together with the house contained in the concrete hole field prices round Rs 3 lakh,” says Nanma including that the prototype was featured on BBC’s World Podcast, ‘The Local weather Query’.
A future-proof know-how
Whereas pursuing her post-graduation, Nanma bought a chance to do an internship on the Delft College of Expertise (TU Delft) within the Netherlands.
“That’s once I first bought to see the working of amphibious buildings at Maasbommel within the Netherlands. There have been round 32 homes that appear like abnormal homes that relaxation on the bottom. However when the floodwaters hit, the buoyant basis of the home lifts it,” remembers Nanma.

Amphibious homes are fabricated from sturdy concrete but light-weight buoyant foundations which might be able to briefly floating throughout floods. These stand up by steerage posts or pillar parts which assist them to remain in the identical place with out letting the home float away. Later when the water recedes the constructing will return to the bottom.
“This know-how is best than statically elevated buildings in flood-prone areas. The buoyant basis of the constructing permits the home to drift. They’re made as both a concrete hole field or as a mixture of concrete with EPS (Expandable PolyStyrene) blocks,” she says, including that the strategy is set primarily based on web site circumstances.
Although the know-how is just not as widespread as floating homes, there are a number of amphibious homes in nations just like the Netherlands and UK. “These fashions of homes, that may be constructed as much as three tales, are inexpensive when in comparison with regular concrete homes. In contrast to the standard manner, there’s much less utilization of cement as we use prefabricated panels to construct the home,” she elaborates.
“For an amphibious home of 600 sqft fabricated from panels and prefabricated construction and an additional 600 sq ft contained in the concrete, hole field basis will price round Rs 15 lakh. However the fee might fluctuate from Rs 1,500/sqft to Rs 2,700/sqft, relying on the positioning circumstances and the consumer’s particular wants,” she explains.
Hari Mohan from Kottayam, a journalist and a consumer of NestAbide says, “I’ve been planning to construct a brand new home close to the banks of Meenachil river, which is of course a flood-prone space. When it floods within the space, the water may even rise to a top of 6 ft. So, once I determined to construct a brand new home, I needed to search for an answer. That’s once I heard about NestAbide and their amphibious housing initiatives.”

“After discussing it with Nanma and Ben, I made a decision to construct an amphibious home which aligns with my necessities and is extra inexpensive than a standard home. It is going to be two-storeyed with one flooring beneath the bottom contained in the pillars which might rise when there’s a flooding scenario. The planning is all finished and we’re ready to begin the development by September after the rains,” he elaborates.
Aside from amphibious housing, NestAbide can be an architectural and structural design consultancy agency with interdisciplinary engineers, architects, science graduates, and so forth. With 10 full-time workers and 33 on-call consultants the agency additionally focuses on different flood-resilient applied sciences.
Nanma and Ben, are presently pursuing their PhD on the Delft College of Expertise beneath the supervision of prof Dr Chris Zevenbergen at TU Delft and UNESCO IHE, Delft. Lately, they had been featured within the Forbes 30 Beneath 30 Asia Listing 2022 for his or her initiative.
“At the moment, we’re engaged on an amphibious housing challenge for individuals dwelling in flood-prone areas of Kuttanad and Munroe Island, funded by KDISC (Kerala Improvement Innovation and Strategic Council),” says Ben.
“The houses are both totally or partially funded by the Authorities by KDISC, for chosen beneficiaries from each areas, for which the purposes are open now. The group is guided by our mentors and an skilled committee shaped beneath KDISC together with famend architects, marine engineers, authorities engineers and structural engineers,” he concludes.
