Dalmia Bharat Group has made an initial investment of Rs 50 crore in PRITHU, a startup company in the realty sector. Over the next five years, Prithu is targeting an annual turnover of over Rs 500 crore. The initial investment gives Dalmia a 74 per cent stake, and the balance will be held by Nitin Bansal, Managing Director, PRITHU. PRITHU-built homes are designed for sustainable living, and will seek to be GRIHA (Green Rating for Integrated Habitat Assessment) certified. They include built-in safety and security features, and will cost between Rs 2,300 to Rs 6,000 per sq ft, covering all design, construction and approvals costs. Better design, appropriate materials and certified construction quality ensure greater energy-efficiency and lower maintenance costs. PRITHU also promises timely delivery and one year of free maintenance post handover.
