You can find a number of well-known nationalised banks, private banks, and ATMs within a 1-kilometre radius because the area is well-developed. There are numerous healthcare facilities within 1 km, well-equipped with contemporary technology.

The area of Thirumazhisai is nice. The major road, market, schools, temples, hospital, and bus station are all easily accessible. The prestigious Panimalar Engineering College and Poonamallee Bus Depot are also close to this property.
