Casagrand Osaka
Casagrand Osaka is a residential apartment project in Porur and Iyyapanthangal, Chennai, developed by CasaGrand. The project is under construction. It is spread across 6.8 acres and comprises 401 units in total, developed across two phases. That makes Osaka one of the larger multi-phase developments on this site by total unit count.
Casagrand Osaka offers 2, 3 and 4 BHK configurations, with a second phase adding two further 3 BHK sizes. The 2 BHK homes, at 1,012 sq ft and 1,177 sq ft, are sold out. The 3 BHK starts at 1,430 sq ft, priced from ₹96 lakh, the entry point into the project today.
A larger first-phase 3 BHK reaches 1,576 sq ft, priced from ₹1.04 crore. Phase two adds two further 3 BHK sizes, priced from ₹1.07 crore and ₹1.17 crore respectively. The 4 BHK also comes in two sizes, priced from ₹1.66 crore and ₹1.67 crore, and runs up to 2,518 sq ft. Casagrand Osaka is registered under RERA number TN/1/BUILDING/0243/2025.
The project's amenity list runs across social, recreational and wellness spaces. It includes a multi-purpose lawn, an amphitheatre and pet parks, alongside a lap pool, a kids pool and a terrace cinema. Indoor spaces add a games room, a banquet hall, a co-working space and a salon, plus a Japanese tea room and bamboo courts. A buyer should ask which of these amenities are already complete and which remain part of a later construction stage.
The smallest available 3 BHK at 1,430 sq ft works out to roughly ₹6,700 a sq ft. Because construction is ongoing, payment typically follows the pace of work on site. A buyer should read the payment schedule carefully and track it against visible progress before each instalment is due, rather than paying ahead of the work actually completed on site. Buyers using a home loan should also confirm the bank's valuation matches the agreement value before the loan is sanctioned.

Casagrand Osaka Location
Casagrand Osaka is located in Porur and Iyyapanthangal, in Chennai. This is the location this listing shows for the project, and the developer's page does not state a fuller street address or a specific landmark.
Porur and the surrounding Iyyapanthangal belt have seen sustained apartment development in Chennai over recent years. A buyer should independently confirm current travel times, road access and nearby infrastructure before booking, since these specifics fall outside this listing.
Because Casagrand Osaka is still under construction, a site visit today will show the building at its current stage of work rather than the finished product. Buyers evaluating this belt should also ask about upcoming road-widening or transit work, since these can change access over the life of the loan.

| 2 BHK | 1177 Sq.ft |

Casagrand Osaka floor plans span three bedroom counts across two phases. The 2 BHK homes are available at 1,012 sq ft and 1,177 sq ft, though both sizes are sold out with the developer.
The 3 BHK is offered at 1,430 sq ft and, with an additional toilet, at 1,576 sq ft, priced from ₹96 lakh and ₹1.04 crore respectively. A second phase adds two more 3 BHK sizes, at 1,581 sq ft and 1,757 sq ft.
The 4 BHK is the largest configuration, running from 2,495 sq ft to 2,518 sq ft. A buyer choosing between the original launch and the second phase should ask the developer which amenities and blocks differ between the two. Buyers weighing the original launch against the second phase should compare not just price but also floor, facing and distance from the amenity blocks before deciding.
Casagrand Osaka Master Plan
Casagrand Osaka is built on 6.8 acres and will comprise 401 units in total once complete. This listing does not state the number of towers or floors.
The project has been developed in phases, with a second phase adding further 3 BHK sizes beyond the original launch. A buyer should ask which phase a specific unit belongs to, since amenities and handover dates can differ between phases in a project of this scale.
Since construction is ongoing, the master plan is still being built out rather than finished. Buyers should also ask whether the two phases share the same clubhouse and outdoor amenity blocks or maintain them separately, since this affects long-term maintenance charges.
Casagrand Osaka Amenities
Casagrand Osaka carries an extensive amenity list spanning outdoor, wellness and social spaces. Outdoor features include a multi-purpose lawn, an amphitheatre, a party lawn, a grilling station and pet parks, alongside bamboo courts and zen gardens.
Wellness features include a meditation deck, a koi pond, a yoga deck, a lap pool and a kids pool. Social and indoor spaces add a terrace cinema, a Japanese tea room, an indoor games room, a banquet hall, a co-working space and a salon.
Since the project is still under construction, these amenities are not yet available for a walkthrough. A buyer should ask the developer which of these amenities are shared across both phases of the project and which are specific to a single block.
Casagrand Osaka Price & Payment
Casagrand Osaka is priced from ₹96 lakh for the 3 BHK at 1,430 sq ft, which works out to roughly ₹6,700 a sq ft. The largest 4 BHK, at 2,518 sq ft, is priced from ₹1.67 crore, and the second-phase 3 BHK units start from ₹1.07 crore.
Because the project is under construction, payment is typically linked to construction milestones rather than paid upfront.
An under-construction home like this attracts GST on the construction component, in addition to stamp duty and registration charges that apply to every purchase regardless of stage. Buyers should factor all three into the total outlay before booking. Buyers using a home loan should also confirm the bank's valuation aligns with the agreement value before the loan is sanctioned.
Casagrand Osaka Approvals & Documents
Casagrand Osaka is registered under Tamil Nadu RERA with the number TN/1/BUILDING/0243/2025. Buyers should verify this registration on the Tamil Nadu RERA portal before making any payment towards the project.
Since the project is still under construction, there is no occupancy certificate yet. Buyers should instead ask to see the approved building plan and the land title documents, and revisit the khata and tax paperwork closer to possession. It is also worth asking whether phase one and phase two of the project carry separate RERA registrations, since this listing shows only one. A lawyer's title check is also worthwhile before booking any under-construction unit.
