Casagrand Premier Builder Limited is an Indian real estate developer headquartered in Chennai, Tamil Nadu, established in 2003. Between January 2017 and March 2024, the company held approximately 24% market share in residential project launches and 20% of demand in Chennai. That scale, built over two decades out of its Thiruvanmiyur headquarters, gives Casagrand both the land-acquisition muscle and the construction track record to operate meaningfully in newer corridors — including the Kelambakkam–Vandalur Road belt, where Sonallur and Mambakkam sit.
Under the leadership of founder Arun MN, Casagrand has expanded across key micro-markets in Chennai, offering apartments and independent villas in luxury, mid-range, and affordable segments, with a particular focus on mid-range offerings. As of April 2026, the company had delivered 103 completed projects encompassing 21.79 million square feet of saleable area and had 57 ongoing projects spanning 44.10 million square feet.
Casagrand GoldenGrove is a gated villa community located at Mambakkam along the Kelambakkam–Vandalur Road. The project is spread across approximately 5.8 acres of planned land. It comprises around 116 contemporary 3 BHK independent villas designed with modern architecture, ample ventilation, and 100% Vaastu compliance.
With 116 villas set across 5.8 acres, GoldenGrove maintains an efficient building footprint where 60% of the land area is open space. The community features 116 finest 3 BHK+3T villas with 55+ lifestyle amenities across outdoor and indoor recreational facilities, anchored by a 6,000 sq ft clubhouse and a 3,000 sq ft rooftop swimming pool with a kids pool and deck area.
The project is registered with TNRERA under IDs TN/35/Building/0014/2025 dated 10-01-2025 and TN/35/Building/0106/2025 dated 04-04-2025, with 3 BHK unit areas of 1,949 sq ft. The project was launched in March 2025, offers villas ranging from 1,390 to 2,299 sq ft, and possession is expected from December 2027.
Casagrand has made a deliberate pattern of building in rapidly developing areas with good transportation options and thriving commercial and social infrastructure. Across Chennai, its projects span OMR, ECR, Mogappair, Anna Nagar, Madhavaram, Korattur, Sholinganallur, Poonamallee, Manapakkam, Medavakkam, Pallavaram, Oragadam, and Thalambur. Mambakkam and Sonallur fit the same template — an under-served residential pocket on an established arterial road, with institutional anchors already in place.
The 18-km stretch along the Kelambakkam–Vandalur Road has seen a large number of plotted and residential developments, with adjoining localities such as Kandigai, Mambakkam, Kolapakkam, Varadarajapuram, Nallambakkam, and Melakottaiyur all active. The upcoming bus stand at Kilambakkam has further boosted land values along this highway.
The Kelambakkam–Vandalur Road (SH-121) and the Mambakkam–Medavakkam Road are the two major roads through Mambakkam, linking it to the rest of the city. The stretch also acts as a significant link between OMR and GST Road, and Vandalur Railway Station serves residents of this belt. Mambakkam is approximately 22 km from Chennai International Airport, with Urappakkam Railway Station reachable at 15 km via the Kelambakkam–Vandalur Road.
Velammal Vidhyashram and Maharishi Vidya Mandir are among the schools serving the Mambakkam locality. St. Francis De Sales Matriculation School and the IIT Madras Thaiyur Campus are also in close proximity to the Sonallur address. SBIOA International School is among the notable educational landmarks near Casagrand GoldenGrove.
Chettinad Hospital and Research Institute, Chettinad Hospital, and Supreme Speciality Hospitals are among the medical centres accessible from the Vandalur–Kelambakkam Road belt. A Health and Wellness Centre and Pudupakkam Primary Health Center are also close to the Sonallur project site.
SIPCOT IT Park is accessible at approximately 11 km, while Chennai One IT SEZ and Futura Tech Park are within 18 km of the Mambakkam locality. IIT Madras' expansion for research work at Thaiyur represents one of the significant institutional anchors on this corridor. For buyers employed along OMR — covering Siruseri, Navalur, and Sholinganallur — the Kelambakkam–Vandalur Road offers a cross-corridor route that avoids central Chennai traffic.
Flat prices in Mambakkam broadly range from Rs 4,150 to Rs 6,500 per square foot. Flat rates in Mambakkam recorded a 17.4% change in the last year, 13.7% over three years, and 9.1% over five years. Casagrand GoldenGrove, as a low-density villa product with only 116 units on 5.8 acres, occupies a distinct position above this average — the open-space ratio and independent-villa format command a premium over the apartment baseline in the same postcode.
Chennai's residential market recorded a 10% year-on-year rise in Q2 2025, with 5,861 launches and 4,911 units sold — and even as India's top seven cities saw a 20% decline in housing sales during the same quarter, Chennai posted a 24% surge in residential sales. Unlike more speculative markets, Chennai's property prices are driven largely by end-user demand, employment growth, and infrastructure development, resulting in steady, predictable appreciation rather than sharp cycles.
GoldenGrove is not an isolated bet on Mambakkam. Casagrand already operates Casagrand Cheers in nearby Pudupakkam and has projects across the broader south Chennai belt including Sholinganallur, Pallikaranai, Pallavaram, and Navalur. In May 2024, Casagrand launched a 30-acre township — Casagrand HolaChennai — in Sholinganallur on OMR, comprising 1,818 homes. This pattern of anchoring large-format projects along south Chennai's outer corridors makes Sonallur a logical westward extension of that same strategy.
In 2024, Casagrand's subsidiary Casagrand Premier received SEBI approval for an initial public offering — a development that brings additional scrutiny and financial discipline to its ongoing construction pipeline, including projects like GoldenGrove that are currently under construction and scheduled for December 2027 possession.
