The residential real estate market along GST Road (Grand Southern Trunk Road / NH-45) has witnessed a remarkable transformation over the last two decades. Once considered a peripheral stretch outside the core city, GST Road is today one of the fastest-emerging residential investment corridors near Chennai, driven by infrastructure growth, connectivity, and affordability.

GST Road Real Estate Market – Past Scenario

Early Development Phase (Before 2010)
In the early years, GST Road was primarily known for:

• Industrial units and warehouses
• Large vacant land parcels
• Sparse residential settlements

Residential demand was limited due to:

• Distance from central Chennai
• Limited social infrastructure
• Low urban density

During this phase, property prices were highly affordable, making the corridor suitable mainly for land banking and long-term investors.

Growth Phase (2010–2018)
Between 2010 and 2018, GST Road began to gain attention as:

• City limits expanded southward
• Airport accessibility improved
• Suburban rail connectivity strengthened

Residential prices during this period:

• Apartments and plots ranged approximately between Rs 1,200 – Rs 2,000 per sq.ft
• Demand was steady but not aggressive
• End-users were still limited compared to other corridors

Overall, appreciation was gradual and organic rather than speculative.
