The prices of up-market residential localities in big metros have witnessed a 20-25% rise in the last four months. Markets such as Greater Kailash I & II, Jorbagh, Golf Links, Amrita Shergil Marg, Sunder Nagar, Vasant Vihar and Shanti Niketan in Delhi, Napean Sea Road, Peddar Road, Breach Candy, Malabar Hills in Mumbai and Richmond Town, Lavelle Road, Cunningham Road in Bangalore have a witnessed a spurt in prices. In Mumbai, the prices in posh areas such as Altamount Road, Napean Sea Road, Nariman Point and Churchgate have gone up by 20-25%. But South Delhi is leading, the market quoted prices as high as Rs 5 lakh to Rs 10 lakh per sq yard. Mr.Vikram Sabharwal, MD of SABH Infrastructure, said, "The prime localities in South Delhi are commanding a huge premium as there is virtually no land available in these posh areas. There is hardly any construction activity taking place. The only activity seen is in large villas being converted into luxury apartments. This has further jacked up demand and the corresponding prices."
