The verdict

Where you should look first

One line on the same metro route as Besant Nagar, flood-safer and on budget.

🥇 Winner

OMR — Sholinganallur / Navalur WEST

The only area whose metro line actually reaches your Besant Nagar side (Corridor 3 → Adyar / Thiruvanmiyur, 2026–28). A plot costs ₹50–70 L, leaving ₹2.3 Cr+ to build — with a 30–40 min drive already today.

  • ✅ Metro: same line as office
  • ✅ Flood-safe west-of-OMR pockets
  • ✅ 30–40 min drive today
🥈 Runner-up

Kelambakkam (west of OMR)

Cheapest metro-linked plot (₹50–60 L), single-seat ride to Besant Nagar once Corridor 3 reaches SIPCOT. Trade-off: a longer car commute today and stricter pocket selection near the marsh.

  • ✅ Cheapest metro plot on the line
  • ⚠️ Longer drive until metro opens
  • ⚠️ Must pick west-of-OMR high ground
