Casagrand Osaka is a residential apartment project by Casagrand at Bhel Nagar, Iyyappanthangal, in the Porur belt of West Chennai. It is registered with Tamil Nadu RERA under number TN/1/Building/0243/2025, dated 4 July 2025. Some marketing content refers to this project simply as “Casagrand Porur,” which appears to be a looser, non-official name for the same Osaka project rather than a separate development.
Location & Connectivity
The project is located in Iyyappanthangal, part of the wider Porur residential corridor in West Chennai, with access to Porur Junction, Chennai Bypass Road and Chennai International Airport. This area has developed around IT and business corridor connectivity toward Guindy, Vadapalani and Mount-Poonamallee Road. Actual commute times should be verified independently.
Project Specifications
The project is spread across approximately 6.8 acres and comprises 401 units across 3 towers. The unit mix includes 2, 3 and 4 BHK apartments, with sizes reported in a fairly wide range depending on the source: roughly 946 to 2,518 sq. ft. (super area) in one listing, and 1,140–1,177 sq. ft. (2 BHK), 1,426–1,975 sq. ft. (3 BHK) and 2,488–2,495 sq. ft. (4 BHK) carpet area in another. The project includes a Japanese-themed design concept with Zen gardens and a Japanese tea room among its amenities.
Pricing
Quoted starting prices vary by source: 2 BHK from approximately Rs 47–53 Lakh, 3 BHK from approximately Rs 76 Lakh, and 4 BHK reported anywhere from roughly Rs 1.08 Crore to over Rs 1.4 Crore depending on the listing. Given this spread, request the current official cost sheet by tower, floor and configuration rather than relying on any single quoted figure.
Amenities
Advertised amenities include a clubhouse, swimming pool, gym, Zen garden, Japanese tea room, mini theatre, amphitheatre, kids’ play area, sports courts, yoga deck, jogging track, party hall, co-working space, landscaped gardens and 24/7 security — more than 100 amenities in total per project listings.
RERA & Compliance
The project’s Tamil Nadu RERA registration number is TN/1/Building/0243/2025, dated 4 July 2025. This can be verified directly on the TN RERA portal for the sanctioned plan and promoter details. The project status is listed as ongoing.
A Few Honest Notes
Unit sizes and prices for this project are quoted inconsistently across sources — both the size ranges (946–2,518 sq. ft. vs the more granular per-configuration figures) and the 4 BHK price (Rs 1.08 Cr vs over Rs 1.4 Cr) don’t fully reconcile. This is common where a project is marketed under two different names (“Osaka” and “Porur”) across different listing networks, and it’s worth confirming the exact configuration, size and price directly against the RERA filing rather than any single aggregator listing.
Verdict
Casagrand Osaka has a verifiable RERA registration and a confirmed project scale (6.8 acres, 401 units, 3 towers), so there’s a real project here to evaluate. Because pricing and unit-size figures vary meaningfully across sources, and because it circulates under two different marketing names, buyers should get written, RERA-consistent specifications directly from Casagrand before treating any online listing as final.
