Top 10 Luxury Apartments in Chennai 2026: Ready and Nearly Ready

Our top 10 luxury apartments in Chennai are ten towers on the TN RERA register that are finished or due by 31 December 2026. We checked each one on 28 October 2026, and they're in Guindy, Kilpauk and Vepery, RA Puram and Mandaveli, Nungambakkam, Thiruvanmiyur and on ECR. We group them by area and list them A to Z inside each group, so the order is not a ranking.

TN RERA is the Tamil Nadu Real Estate Regulatory Authority. A building project must register with it if it has more than eight homes or more than 500 sq m of land. Its entry lists the approvals and the promised completion date.

Our luxury apartments in Chennai guide explains what luxury means here and what each area costs per sq ft. It also profiles five central towers due from 2027, so they aren't repeated below. For homes you'd book today and move into later, see our list of upcoming luxury flats in Chennai.

No one certifies a flat as luxury, so we used three filters. First, the project had to be on TN RERA's building lists, complete or due by the end of 2026. Second, it had to be in central or south Chennai, or on ECR. Third, it had to be built for the top end. That meant three-bedroom and larger homes, homes of about 2,000 sq ft and up, or deep basements and few homes a floor.

Every fact comes from two places: the project's TN RERA list entry and the developer's own project page, both read on 28 October 2026. We haven't used listing-site prices for any named project. Where a developer doesn't print a price, we say so.

Guindy has three of the ten, on Velachery Road and Five Furlong Road. Two are by Appaswamy and share the same Velachery Road door number on their RERA records.

Appaswamy Malkoha

The RERA entry describes 74 homes over 12 floors, with a gym and pool on the 13th. Appaswamy lists 36 three-bedroom homes of 2,609 to 2,765 sq ft and 38 four-bedroom homes of 3,702 to 3,921 sq ft. The land is 19.28 grounds, and the page shows a completion certificate dated 23 June 2026. It doesn't print a price, or say whether those sizes are carpet or super built-up.

Appaswamy Parkhouse Mews

Parkhouse Mews is the older, smaller-format neighbour: 95 homes over 14 floors with a pool on the terrace. Appaswamy lists 68 three-bedroom homes of 1,886 to 2,034 sq ft and 27 four-bedroom homes of 2,489 to 2,608 sq ft. Its completion certificate is dated 4 February 2025, and the page doesn't print a price.

Purva Somerset House

Puravankara's building on Five Furlong Road has 181 homes, three basement levels and 12 floors on its RERA record. The developer lists three, four and five-bedroom homes and penthouses in one tower with four wings, on about 1.92 acres. It says ready to move in and prints a starting price of ₹3.20 crore. The RERA completion date of 31 March 2023 was extended to 30 September 2024.

North of the city centre, Rainbow Foundations has two of the ten. Both are marked sold out, so you'd be buying from an owner.

Rainbow Crystal Heights

This Purasawakkam High Road project was first registered in 2022 with 56 homes. A revised plan of two towers and 126 homes was registered in May 2024. Rainbow lists three and four-bedroom homes of 2,195 to 4,400 sq ft over 18 floors. The RERA completion date moved from 31 December 2025 to 31 December 2026, while Rainbow's page gives 2025 as the year built.

Rainbow Prestige

Rainbow Prestige is a boutique building of 18 homes: a basement, a stilt floor and nine floors on Vepery High Road. Rainbow lists only three-bedroom homes, of 2,200 to 2,800 sq ft. Its page says built in 2024. The RERA entry still shows a 31 December 2026 completion date and a June 2025 progress note, so ask for the completion certificate.

RA Puram and Mandaveli sit next to Mylapore, north of the Adyar river, where our guide's research finds some of Chennai's highest asking rates. Both towers here are complete.

Appaswamy Navasuja

Navasuja, on Venkatakrishna Road in RA Puram, has 59 homes over 15 floors and double basements on its RERA record. Appaswamy lists 45 three-bedroom homes of 2,020 to 2,096 sq ft and 14 four-bedroom homes of 2,615 sq ft, on 15 grounds. A ground (2,400 sq ft) is Chennai's usual land unit. The completion certificate is dated 30 September 2024.

Casagrand Olympus

Olympus is a slim tower on South Canal Bank Road with 38 homes, a basement, a stilt floor and 19 floors. TN RERA marks it complete, with an October 2020 date. Casagrand lists three-bedroom homes of 1,851 to 2,017 sq ft of built-up area, two on each floor, on 9 grounds. Its page still shows ₹17,350 per sq ft for the 2,017 sq ft home, about ₹3.5 crore. Treat that as Casagrand's last listed rate, not a resale price.

Kalpataru One Crest

This Nungambakkam High Road tower is registered by Kara Property Ventures LLP. Its address on the record is Kalpataru's office in Mumbai. The entry describes 47 homes, four basement levels, 16 floors and a terrace pool. Kalpataru lists it among completed projects, with four-bedroom homes, five-bedroom duplexes and five-bedroom super duplexes. The RERA entry still shows March 2021 and a September 2020 progress note, so check the completion certificate.

Baashyaam The Plutus Residence

On Lattice Bridge Road in Indira Nagar, where Adyar meets Thiruvanmiyur, this tower has 152 homes over 18 floors. Its RERA record lists three basement levels, two-level mechanised parking and a pool on the 18th floor. It's marked complete, with a date of 21 August 2024. Baashyaam's website didn't load when we checked, so we haven't confirmed home sizes.

Casagrand ECR14 Signature

The Signature tower holds 26 homes inside Casagrand ECR 14, a 577-home project in Kanathur on East Coast Road. TN RERA marks the whole project complete. Casagrand lists the tower's homes at 5,037 to 5,093 sq ft, two to a floor, all sold out. The page calls them four-bedroom in one place and five-bedroom in another, so check the plan.

Four of the ten carry 2025 or 2026 dates on their certificates or RERA records. Appaswamy Malkoha's completion certificate is from June 2026, and Parkhouse Mews' from February 2025. Rainbow Crystal Heights says built in 2025, and Rainbow Prestige says 2024, while both RERA records run to the end of 2026.

A new flat sold by the builder after its completion certificate carries no GST. That makes these a different purchase from a home booked off plan, which pays 5% GST. Our under construction vs ready to move guide weighs the two. Malkoha, Parkhouse Mews and Somerset House show a ready-to-move status rather than sold out, so ask each what's left.

Only two developers print a figure. Somerset House starts at ₹3.20 crore, and the Olympus page shows ₹17,350 per sq ft. The rest are sold out or price on request, so ticket size has to come from the home's size and the area's rate.

The biggest homes are the ECR tower's 5,000 sq ft units and Malkoha's four-bedroom homes of up to 3,921 sq ft (364 sq m). Size alone doesn't set the price, though. A 2,500 sq ft home at ₹20,000 per sq ft is ₹5 crore, and the same home at ₹30,000 is ₹7.5 crore.

Most sizes above don't say what they measure. Super built-up area adds a share of lobbies, lifts and the clubhouse to your carpet area, the floor inside your walls. So ask for the carpet area on the RERA record before you compare one price with another.

1. See the completion certificate. Several RERA entries above still show old dates or progress notes. Appaswamy and Puravankara print certificate numbers on their pages, so ask every seller for the same document.
2. Read the TN RERA entry yourself. Look at extensions, the last progress note and any bank or mortgage notes. Our RERA checklist shows what each part means.
3. Trace the resale chain. Several are sold out, so you'd buy from an owner. Check each earlier sale deed and the undivided share of land (UDS), the slice of the plot that goes with the flat.
4. Budget the duty. Above ₹3 crore, a resale flat pays 7% stamp duty and a 2% registration fee, 9% in all. On a ₹4 crore flat that's ₹36 lakh, charged on the government's value for the flat if that's higher than your price.
5. Ask about upkeep. Deep basements, mechanised parking and terrace pools cost money to run. Get the monthly maintenance and the corpus fund in writing.

To run the numbers, use our stamp duty calculator and compare areas on Chennai property rates. Not every tall tower made the list: our tracked Appaswamy Altezza page on OMR shows a mix of 2BHK to 4BHK homes. Buyers abroad can start with our NRI buying guide.
