Kerala Sisters Build Climate-Responsive Home on Ancestral Land
Two sisters built a house together on land that came from their mother’s family.
They wanted the home to stay comfortable without always using air conditioning.
An architect studied the direction of the wind before designing the rooms.
Openings, high ceilings and clay lattice walls help air move through the house.
Laterite walls slow down heat, while the layered tile roof helps protect the rooms from sun and rain.
The sisters kept many trees that their grandmother had planted.
The house was finished in December 2024.
They hope their children and grandchildren will keep returning to the family land.
Sisters Renu Krishnadas and Rekha Utham built Kadangotu House on a 70-cent ancestral plot near Kannur.
Architect Amrutha Kishor designed the home around airflow, high ceilings, laterite walls and clay-tile roofing.
Renu says she stayed for 21 days without switching on the air conditioner, using only fans when needed.
The sisters preserved existing trees, used local materials and hired local workers during construction.
Completed in December 2024, the home hosted a Theyyam performance that brought together family and villagers.
