TIDEL Park, Chennai, Technology park in Tharamani, Chennai, India

TIDEL Park is a 13-storey information technology building on Rajiv Gandhi Salai in Taramani, Chennai. Its pale grey tiled and concrete exterior carries a tall central curtain wall of blue reflective glass, with a white X set in a square panel low on the left; white blocks with rows of smaller windows step back to the right. A red "TIDEL" sign stands on the roof above the glass section. Inside, eight sections flank central atria, with 19 elevators and 2 escalators.

The building opened in 2000 as one of the first major IT centers outside the city core of Chennai. Its completion helped transform the Tharamani neighborhood into a technology corridor that later attracted similar projects.

The name TIDEL is a portmanteau of TIDCO and ELCOT, the two Tamil Nadu government agencies that developed the park. The ground floor and first floor hold restaurants, banks, shops, health clubs and a 16,000 sq ft food court, where employees from the building's offices gather during breaks.

Tharamani metro station lies within walking distance and provides direct access to the rest of Chennai. Visitors can enter the ground floor area but need prior clearance or an appointment to access office floors.

The building uses rooftop rainwater harvesting systems to supplement water supply during monsoon season. These collection tanks feed into sanitation and cooling systems during the heavy rainfall months.
