Amazonia in Rajarhat, Kolkata: Upcoming Kosmic Estate Apartment Project

Status as of October 2026

As of October 2026, Amazonia is listed as upcoming. Listing sites do not agree on its stage. One portal tags the project as a new launch and shows 35% of units sold, without a date on that figure. Another portal shows it as under construction with 1,850 units and a 15-acre total area.

Taken together, the portal data points to a project that is selling and building at the same time. The date of any formal launch event is not part of the public record reviewed for this article, so no launch date is given here.

Project layout and product

The project is described as 21 petal-shaped high-rise residential towers spread across 15 acres. Listed floor counts are G+11, G+17 and G+18. The listing shows 1,521 units, while one other portal gives 1,850. The developer's listing says units have private decks.

The project is apartments only. It has no villas, plots or commercial units. A central landscape area of about 1.4 lakh sq ft and a themed podium garden of about 1.5 lakh sq ft are listed as open space.

Configurations and prices

Partner listings show the following base prices, with data dated 19 November 2024. Prices were stated before any fresh pricing round and may have changed.

A more recent portal listing shows a band of ₹63.84 lakh to ₹1.27 crore. A comparable-projects table lists the project average at ₹4,900 per sq ft. Partner listings state a 10% booking amount, with no staged payment schedule shown.

Possession timeline

Partner pages list possession for 1 December 2026, and one page says the homes will be ready for possession by December 2026. Those pages were last updated in 2023 and 2024, so the date should be checked against the developer's current schedule. Under the RERA rules, a registered project's possession date is the one to rely on.

Amenities

• Two clubhouses totalling 22,000 sq ft at ground and podium levels, with two ozonised swimming pools. The developer's listing calls these the city's first.
• A fully equipped air-conditioned gym with a cardio studio.
• A themed lifestyle podium garden, a zen garden with sit-outs, and a 3.5-acre themed garden.
• Badminton, basketball and mini golf courts, a jogging track, cycle track, tennis court and box cricket pitch.
• A mega lifestyle mall is listed as attached to the project.
• Two-level podium parking plus open parking, 24x7 CCTV and high-speed lifts.

Location and connectivity

The project sits on Rajarhat Main Road. Partner listings say the locality is about 3 km from Kolkata International Airport. Dum Dum Cantonment railway station is listed at about 3.94 km, and Dum Dum Metro station is also nearby. Central Kolkata is listed as 45 to 70 minutes away.

Nearby schools, hospitals and malls are listed within a few kilometres. These include Big Bazar Chinar Park, about 0.4 km away, and several multispeciality hospitals within 1.4 km.

Infrastructure under way

The Orange Line metro is the main transit project in the area. A trade report says the Chingrighata viaduct gap, which had delayed the line for more than six years, has now been closed. That report says a New Garia to Sector V service may open by December 2026, and that the Beleghata to IT Centre section is working toward a 31 December deadline. Once that stretch opens, the trip from New Garia to Sector V is expected to take about 30 minutes.

A proposed flyover linking the Eastern Metropolitan Bypass with Rajarhat-New Town is estimated at around ₹900 crore. It is a proposal, not a sanctioned project.

Local market context

Partner and portal data put the average asking price in Rajarhat at ₹6,200 per sq ft, and the Rajarhat Road average sale price at ₹4,950 per sq ft, with a rental yield of 3.9%. Rents range from ₹15,000 to ₹90,000 a month across studio, 1 to 4 BHK and villa types.

Nearby projects show a wide price spread. Siddha Happyville is listed at ₹60.98 lakh to ₹1.83 crore, Magnolia Merlion at ₹48.52 lakh to ₹68.74 lakh, and Loharuka Urban Vista at ₹60 lakh for 2 to 3 BHK homes.
