Iki Builds Designs Sustainable Home in India Using Local Stone and Earth Materials

A geological palette of rammed earth, local stone and terracotta tiles reflects the rugged, rocky character of the nearby Deccan Plateau at this home in South India, designed by local architecture studio Iki Builds.

Named Aurva Illam – a combination of the Sanskrit word Aurva, meaning 'of the earth' and the Tamil word Illam, meaning 'home' – the dwelling is located on the outskirts of Chennai.

The house is designed as a series of cascading vaulted roofs that follow the natural slope of the site, creating a terraced effect that blends with the landscape.

Local materials were chosen not just for their aesthetic qualities but also for their thermal properties, helping to regulate indoor temperatures naturally.

The design prioritizes natural ventilation and passive cooling strategies, reducing the need for mechanical air conditioning in the hot climate.
