The size of the country's real estate industry is expected to reach $1 trillion by 2030 from $200 billion in 2021, according to a joint report prepared by NAREDCO and EY. The report was released on Friday at NAREDCO Finance Conclave held here. The sector is likely to contribute 18-20 per cent to India's GDP by 2030, NAREDCO said in a statement. As per the report, there is a favourable demand-supply gap which will propel the growth of this sector.
