Poonamallee

Major roads, flyovers, metro rail, and ring roads instantly enhance connectivity and reduce travel time. Areas near upcoming expressways or metro stations often see price appreciation before the project is even completed.

A pivotal node in Metro Phase II (Corridor IV), Poonamallee is getting better connected via the Porur–Poonamallee elevated metro, with commercial operations expected around late 2025 
The area is eyed for a double-decker elevated road-cum-metro structure along NH 4, improving logistics and metro accessibility toward the Greenfield airport.

It's on the path of the upcoming Greenfield Airport (Parandur), marketed as a major connectivity and real estate catalyst.

Urban infrastructure and amenities are expanding — ongoing residential projects, schools, hospitals, and future malls (like in nearby Mangadu) are shaping its suburban skyline.

Pedestrian amenities are being upgraded — e.g., construction of a modern foot overbridge near the Ampa Skywalk junction
Example: Poonamallee’s real estate boom accelerated after the announcement of Metro Phase II and the double-decker flyover.
