Sonam Wangchuk's Sustainable Ladakh House
Sonam Wangchuk, a famous climate activist and engineer, has built a special house in Ladakh, a cold and dry place in India.
This house is very eco-friendly and uses old building methods like mud and rammed-earth walls.
These walls help keep the house warm in the winter and cool in the summer without using much energy.
The house also has a smart heating system that uses the sun's heat to keep the house warm at night.
Instead of regular toilets, the house has special toilets that turn waste into compost, which can be used for gardening.
The inside of the house is modern and comfortable, with nice furniture and a big dining area for the family to eat together.
There is also a greenhouse and an apple orchard outside the house.
This house shows how we can live in a way that is good for the environment and uses less water and energy.
Sonam Wangchuk's house in Ladakh is built using mud and rammed-earth techniques for natural insulation.
The house uses a passive solar heating system to maintain indoor temperatures without conventional heaters.
The sanitation system is zero-waste, using composting toilets to conserve water and reduce reliance on centralised sewage.
The interiors are modern and comfortable, blending traditional building methods with contemporary design.
The property includes a greenhouse and an apple orchard, extending sustainability to food production.
