Industries Minister S. Keerthana said the plan will focus on the Pallavaram‑Thoraipakkam Radial Road, Mount‑Poonamallee High Road and Rajiv Gandhi Salai (OMR), designating them as integrated zones with coordinated planning, higher FSI and shared amenities to lure the next generation of GCCs to the city.
According to Jacob, a senior government official, the three corridors were chosen for their existing IT ecosystems and connectivity – the Pallavaram‑Thoraipakkam stretch links directly to Chennai International Airport, Mount‑Poonamallee is set to benefit from the upcoming Poonamallee Metro line, and OMR remains the state’s premier IT hub with a concentration of banking, automotive and professional‑services centres.
Jerry Kingsley, head of research for JLL Chennai, explained that the FSI boost will let existing GCC campuses expand vertically without needing additional land, creating more Grade‑A office space and higher development returns for developers, property owners and investors.
The GCC footprint in Tamil Nadu is already sizable: the state hosts more than 465 GCCs – about 10‑15 % of India’s total – with 405 located in Chennai. GCCs accounted for roughly 55 % of the city’s office leasing in the first half of 2026, up from 49 % in 2025, according to Anarock’s Kanchana Krishnan.
At the Vettri Tamil Nadu Investment Conclave the government sealed MoUs with several multinational firms: Bosch Global Software Technologies will set up an automotive‑software centre; Chubb will expand its insurance‑operations hub; Nordex will launch a product‑engineering GCC; and Ernst & Young (EY) signed a ₹1,000‑crore agreement for a new centre. Other first‑time India entrants such as Japan’s SMBC, HD Supply and Luxembourg’s SES also announced GCC projects in Chennai.
Industry observers say the new centres will drive demand for Grade‑A office space ranging from 30,000 sq ft to several lakh square feet. Chennai’s current rents of ₹76‑₹78 per sq ft still undercut Bengaluru and Hyderabad, giving the city a cost advantage. The influx of skilled professionals is also expected to lift residential values, which have risen about 44 % from ₹4,935 per sq ft in 2020 to ₹7,100 in 2025, with the south‑Chennai belt accounting for the majority of new launches and sales.
Stakeholders caution that the corridor plan must be matched by faster delivery of supporting infrastructure – notably the completion of metro extensions, road upgrades, drainage and public‑transport links – to fully realise the real‑estate multiplier effect seen during the earlier IT boom.
