The rating agency, in its report titled "2012 Outlook: Indian Real Estate Sector", has hinted at a lower growth in the retail commercial space.

"Though over supply of commercial space continues in some markets, the demand for office space (in 2012) is likely to be maintained at 2011 levels due to the anticipated growth in IT/ITeS, which accounts for a substantial demand for office space in India," said the report released here today.

According to a survey by apex infotech outsourcing industry body Nasscom, IT/ITeS sector grew by 21 per cent in FY11 and this growth momentum will continue to 2012.

"Similarly, the expectation of higher employment growth in the sector in Tier II cities will boost demand for commercial and residential space in these cities," the Fitch report said.

However, the demand for new retail space from the organised retail sector is likely to be low as many players, who have grown substantially in the recent past, have sought to consolidate their positions, it said.

The rating agency has forecast a negative outlook for the Indian real estate sector in 2012 due to weak overall demand and higher construction costs, which are likely to continue to squeeze margins.
