Designed as a duplex for a family of three, Sangwan House sits quaintly at a corner plot of 1134 SqFt in Delhi's Karala Village, translating the client’s vision of having a small house but plenty of open space and green. It’s one of Habitat Design Collective’s (HDeCO) low-cost residential projects and has been designed and completed in INR 30 Lac. 

Sangwan house has been constructed using passive building techniques like rat-trap bond walls, which passively insulates the building, increasing the time-lag and reducing material consumption. Further, to reduce heat gain from the terrace, the top slab has been made deeper by using inverted beams and cow-dung-cake filling and with reflective China mosaic finish. The sky-lit courtyard, a quintessential Indian architectural typology, brings in daylight in the deeper interior spaces and also facilitates cross-ventilation.
