About the project
Organization
Kerala's diverse terrain and high construction demands have led to the overuse of highland resources, causing severe environmental imbalances, particularly evident during the 2018 floods. To address this, the initiative promotes sustainable construction using locally available earthen materials and prefabricated steel, reducing reliance on highland stone products. The URVIKOSA research center was established to advance knowledge-sharing on alternative construction methods, receiving national recognition for its sustainability efforts. Two key projects exemplify this approach: the Post-Flood Rapid Housing Project, which built resilient homes in just 14 days, and the Amara Ayurvedic Retreat, which transformed an abandoned quarry into an eco-friendly retreat.
Impact
The initiative enhances skill acquisition by training engineers and laborers in forgotten sustainable techniques. It boosts the regional economy by relying on locally sourced materials and labor. Live models, such as URVIKOSA’s sustainable buildings in Trivandrum, serve as educational hubs. Waste management is improved, as earth-based structures generate minimal debris, and steel can be recycled. Carbon footprint is significantly reduced through minimal cement use, local sourcing, and avoidance of heavy machinery. Water efficiency is achieved via sustainable construction techniques like rammed earth, which consumes less water. Research on earthen solutions for high-rise buildings was completed, demonstrating their potential to reduce Urban temperatures.
Community Engagement
After the 2018 floods, NGOs engaged with district administration, local, and state governments to propose rapid housing solutions. In Kuttanad, an amphibious house design was introduced to tackle waterlogging, gaining interest from 20 families but hindered by funding constraints. The initiative actively collaborates with local governance bodies, affected families, and volunteers to promote sustainable construction.
Policy Influence
Discussions with government officials aimed to amend Kerala’s building regulations to recognize earthen construction and stone free rapid housing solutions. Rapid housing solutions were accepted and implemented for several rehabilitation housing projects including LIFE Mission projects. The initiative continues to advocate for regulatory support for sustainable construction.
