Sathya Prakash Varanashi crafted the ‘Varanashi House’ in Bengaluru as an eco-friendly retreat for his wife Ishala and daughters Gauri and Siri. Designed to stay naturally cool without air conditioning, the home merges thoughtful architecture with sustainability.

Instead of cement walls that trap heat, Varanashi used hollow clay blocks to regulate indoor temperatures. Large sliding doors connect the interiors to the garden, while strategically placed vents allow hot air to escape. “The design promotes cross ventilation, displacement ventilation, and a body-level breeze,” he explains.

French windows ensure continuous airflow, while recycled pine wood and thick granite stone add a rustic charm. As a result, the house remains two to three degrees cooler in summer, proving that sustainable design enhances comfort.

Water plays a crucial role in the home’s climate control. A fish pond, cascading water streams, and an open well help recharge groundwater while keeping the surroundings cool. A rooftop garden above the car porch adds beauty, and a 15,000-litre rainwater tank beneath it ensures water conservation.

Inside, natural materials define the space—red oxide flooring, pine wood interiors, and a chimney-like structure that eliminates the need for artificial cooling. “A house becomes a home when it truly reflects the way a family lives,” says Varanashi. Even after 21 years, this low-maintenance home remains a testament to sustainable and harmonious living.
