Neighbourhood
About Egattur
Egattur is a residential locality on Old Mahabalipuram Road in south Chennai. It lies between Navalur to the north and Kelambakkam to the south.
The locality grew around the technology campuses at Siruseri and Sholinganallur. Much of the demand here comes from people who work within a few kilometres of home.
SIPCOT / Siruseri IT Park is about 2 km away. The TCS Siruseri campus is about 3 km away, with Pacifica Tech Park and ETA Technopark at about 3.5 km and 4 km.

Hiranandani Upscale School is about 2 km away. SSN College of Engineering, Hindustan University and Sathyabama University lie within 12 km. Supreme Speciality Hospitals and Chettinad Health City are about 4 km and 5 km away.
Egattur Connectivity

Metro Connectivity on OMR
The proposed Madhavaram–SIPCOT corridor of Chennai Metro Phase 2 is planned along OMR. It would add future metro connectivity to the locality.
City Context
Chennai and the OMR Corridor
Chennai is the capital of Tamil Nadu and one of India’s principal cities. Its economy rests on IT and IT-enabled services, automotive manufacturing, healthcare, education and port-linked trade.
Over the past two decades, residential growth has moved south and west from the traditional core. Old Mahabalipuram Road, also called the IT Expressway, is the clearest example.
The corridor runs south from Madhya Kailash towards Siruseri and Kelambakkam. It carries a dense mix of technology campuses, business parks and SEZs. SIPCOT / Siruseri IT Park, the TCS Siruseri campus, ETA Technopark and Pacifica Tech Park all sit within this belt.
That job base drives demand for high-rise apartments on OMR. Sholinganallur, Navalur, Egattur, Siruseri and Kelambakkam have each developed their own schools, clinics and shops as a result.
Education and healthcare are well represented, with engineering colleges, universities and multi-speciality hospitals in the catchment. The East Coast Road runs parallel to the east and adds coastal access.
Planned Metro
The proposed Madhavaram–SIPCOT corridor of Chennai Metro Phase 2 is planned to serve this stretch. It would complement the road network already in place.
