Casagrand Osaka — 3 & 4 BHK Apartments in Iyyappanthangal, Chennai

Casagrand Osaka is a residential apartment project by Casagrand in Iyyappanthangal, a locality in West Chennai known for its mix of established residential streets and easy access to Poonamallee High Road. Spread across 3 blocks built as basement, ground floor and 5 upper floors, the RERA-registered development (TN/1/Building/0243/2025) comprises 401 units in 3 BHK and 4 BHK configurations, designed for families looking for spacious, well-planned homes in this part of the city.

Apartment sizes at Casagrand Osaka span a genuinely wide range. The entry-level 3 BHK starts at 1,430 sq. ft. and ₹96 lakh, with larger 3 BHK options at 1,576 sq. ft. (₹1.04 Cr), 1,581 sq. ft. (₹1.07 Cr) and 1,757 sq. ft. (₹1.17 Cr) for buyers who want extra room without moving up to a 4 BHK. The 4 BHK homes run from 2,495 sq. ft. to 2,518 sq. ft., priced between ₹1.66 Cr and ₹1.67 Cr — sized for larger families or buyers who want a dedicated study or guest room built into the layout.

The project's low-rise, 3-block layout keeps the community compact rather than tower-block dense, and the amenity list is built around that everyday-living focus: a clubhouse, swimming pool, fully equipped gymnasium and indoor games room sit alongside a library and reading room and a multipurpose hall for residents' gatherings. Families with children have a dedicated play area, landscaped garden and amphitheatre for outdoor time, while a badminton court, table tennis and a yoga and meditation deck round out the recreational options. A senior citizens' corner is a specific nod to multi-generational households. On the practical side, Casagrand Osaka has 24/7 security with CCTV surveillance, covered visitor parking, power backup, rainwater harvesting, a sewage treatment plant, EV charging points and an in-community supermarket.

Iyyappanthangal itself sits in West Chennai, within reach of Poonamallee High Road and the residential and institutional belt around it — a quieter setting than Chennai's more congested inner-city localities, while still connected to the wider city. For buyers specifically comparing 3 BHK and 4 BHK apartments in West Chennai, that combination of unit variety, low-rise scale and locality access is what puts Casagrand Osaka on the shortlist.

Casagrand Osaka is currently under construction, with possession scheduled for August 2028. Its RERA registration, TN/1/Building/0243/2025, is verified — meaning the project's approvals and construction timeline can be checked directly against the state RERA portal rather than taken on the builder's word alone. Between the verified RERA status, a real spread of 3 BHK and 4 BHK sizes from 1,430 to 2,518 sq. ft., and a 401-unit community with amenities built for family living, Casagrand Osaka is a project worth evaluating closely for anyone house-hunting in Iyyappanthangal.
