Renu Krishnadas and Rekha Utham pooled resources to build a climate-responsive house on their mother’s ancestral land, where terracotta roofs and laterite walls invite breezes that keep the home comfortable in Kerala's humid heat—without relying on air conditioning.
- Home designed for natural ventilation and cooling
- Built on ancestral land with laterite walls and clay roofs
- No air conditioning needed despite Kerala’s humidity
What happened
Sisters Renu Krishnadas and Rekha Utham decided to build a new home on their family’s 70-cent ancestral plot near Kannur, Kerala. Both residing abroad—Renu in Dubai and Rekha in Bahrain—they wanted a residence that would celebrate the land's natural environment and embrace its traditional features. They hired architect Amrutha Kishor, who specializes in climate-responsive design, to create a home that works with the local weather rather than against it.
Instead of the usual approach of designing a structure first and then adding artificial cooling, the architect focused on harnessing natural wind patterns and using materials like laterite stone and terracotta tiles. Key features include high ceilings for heat to rise, perforated lattice walls for airflow, and strategic openings that allow the breeze from nearby paddy fields to circulate continuously indoors, reducing the need for air conditioning.
Why it feels good
The Kadangotu House embodies sustainable living that harmonizes modern comfort with nature. Residents experience a constant flow of fresh air, even as Kerala’s humidity climbs above 80 percent, making the indoors pleasantly cool without mechanical systems. This approach not only cuts down electricity use but also captures the essence of the region’s monsoon climate and traditional Kerala architecture.
The family initially had doubts about certain design choices like the clay perforated 'jali' walls, which many thought might not be durable or practical. However, these elements proved essential for cross-ventilation and adding natural charm. After a 21-day stay, Renu confirmed that the house remained cool and comfortable without switching on air conditioning, relying only on fans to enhance the gentle breeze.
What to enjoy or watch next
Kadangotu House offers an inspiring example for homeowners and architects interested in climate-conscious design, especially in tropical environments. Its success encourages exploring traditional materials and site-specific airflow strategies to reduce energy use while enhancing lifestyle quality. Those curious about sustainable homes might follow similar projects that blend ancestral wisdom with contemporary architecture.
For anyone fascinated by Kerala’s cultural and environmental richness, this project highlights how modern needs can coexist with nature’s rhythms. Watching for new developments in natural cooling techniques, and adaptations for hot, humid climates, could provide further insights into low-impact living solutions that cherish local heritage.
