The tallest tower in Lotte Eco Smart City Thu Thiem features 60 above-ground floors and 5 basements. However, the project is not just a single tower: according to the master plan, it is a complex of 11 towers across 6 plots of land, ranging from 12 to 60 floors.
Recently, I have been receiving this question quite often from clients, especially since Lotte partnered with Phat Dat and the project resumed construction on the morning of October 23, 2026. The issue is the conflicting information online: some sources say 50 floors, others 60, and the office tower is listed as either 44 or 48 floors depending on the document.
In this article, I have compiled all the floor counts from the master plan, architectural renderings, and press releases for side-by-side comparison. Where the data matches, I will confirm it; where it differs, I will point it out clearly. After reading, you will know the exact height of each tower, the developers involved, and the estimated completion timelines.
Architectural rendering of Lotte Eco Smart City Thu Thiem indicating the number of floors for each tower, viewed from the Saigon RiverQuick Answer: The tallest tower in Lotte Eco Smart City Thu Thiem has 60 above-ground floors and 5 basements, located on plot 2-5. Lotte announced this figure at the groundbreaking ceremony on September 2, 2022, and the press continued to cite it when the project resumed on October 23, 2026. The exact height in meters has not yet been officially announced by the developer.
Regarding the 60-story figure, all sources are consistent. Lotte Chairman Shin Dong-bin explicitly mentioned the scale of 5 basements and 60 above-ground floors during his groundbreaking speech in 2022, as reported by The Korea Times. The master plan and the rendering you are viewing also indicate 60F for plot 2-5.
The inconsistency lies in the functional purpose of the 60-story tower:
The most logical interpretation is a mixed-use tower, with offices on the lower levels and a hotel or serviced apartments on the upper levels. However, this is merely my deduction and remains unconfirmed by official developer documents.
What about the 50-story figure you often see online? That information is from an earlier phase. In 2017, numerous articles described the project's highlight as a 50-story tower. From the 2022 groundbreaking onwards, the official number has been 60 above-ground floors.
Quick Answer: Lotte Eco Smart City Thu Thiem comprises 11 towers on 6 plots designated 2-1 to 2-6, covering an area of approximately 7.45–7.54 hectares. The three plots facing the square are dedicated to offices and hotels (24–60 floors). The remaining three plots are residential (12–48 floors). Each plot features a 4-story commercial podium.
Master plan of the 6 plots (2-1 to 2-6) of the Lotte Eco Smart City Thu Thiem projectThe 11-tower count matches Lotte E&C's project design description from 2022. The table below compares the two circulating visual documents: the master site plan and the architectural rendering with floor counts.
| Plot | Function | Floors (Site Plan) | Floors (Rendering) | Match? |
|---|---|---|---|---|
| 2-5 | Office / Hotel, Serviced Apts | 60 | 60 | Floor match, function mismatch |
| 2-3 | Office (2 towers) | 44 + 24 | 48 + 24 | Main tower mismatch: 44 or 48 |
| 2-1 | Hotel (Site Plan) / Office (Rendering) | 24 + 12 | 24 | Rendering omits the 12-story tower |
| 2-6 | High-rise Residential (2 towers) | 48 + 32 | 48 + 36 | Smaller tower mismatch: 32 or 36 |
| 2-4 | High-rise Residential (2 towers) | 24 + 18 | 24 + 18 | Match |
| 2-2 | Lake-side Residential (2 towers) | 18 + 12 | 18 + 12 | Match |
Quick Answer: The office and hotel blocks are located on 3 plots 2-1, 2-3, 2-5, adjacent to the Thu Thiem Central Square, consisting of 5 towers ranging from 12 to 60 floors. Plots 2-1 and 2-3 are fully developed by Phat Dat, with a total floor area of approximately 171,580 sq.m., and construction commenced on October 23, 2026.
Who is building these blocks, and when will they be completed? According to the cooperation agreement announced in 2026, Phat Dat will develop the entirety of the commercial blocks 2-1 and 2-3, along with the 4-story commercial/service podiums and basements. The estimated construction period is 36 months, from October 23, 2026, to October 23, 2029. This is a projected milestone, not a guaranteed handover date.
Quick Answer: The residential component of Lotte Eco Smart City Thu Thiem consists of 6 towers across 3 plots 2-2, 2-4, 2-6, ranging from 12 to 48 floors. The tallest residential tower is 48 floors on plot 2-6. As of October 23, 2026, the residential units have not yet been launched for sale, have no official pricing, and lack a specific construction start date.
Who is developing the residential blocks? Based on the collaboration structure announced in 2026, Phat Dat is co-developing the residential components across all three plots (2-2, 2-4, and 2-6) alongside Lotte. A summary article on Thu Vien Phap Luat estimates around 1,200 units, but I have yet to see this figure in the developer's official documents. Please consider this a reference number.
Quick Answer: Floor numbers vary across sources because the project spans nearly a decade, undergoing design revisions, capital scale changes, and the addition of Phat Dat as a partner in 2026. The most reliable figures at present are 60 above-ground floors and 5 basements. For individual tower floor counts, it is best to wait for the official documentation.
I identify three primary reasons:
Quick Answer: Lotte Eco Smart City Thu Thiem broke ground on the two commercial blocks (2-1 and 2-3) on the morning of October 23, 2026, executed by the Lotte and Phat Dat joint venture. These two blocks are scheduled for a 36-month construction period, targeting October 23, 2029. Construction schedules for the residential towers and the 60-story tower have not yet been announced.
The project has a lengthy history and nearly came to a halt at one point. The key milestones, culminating in the most recent updates, are listed below:
| Timeline | Event |
|---|---|
| Oct 23, 2026 | Construction commenced on blocks 2-1 and 2-3 (commercial, services) |
| Jul 31, 2026 | Lotte Properties HCMC completed payment of 17,569 billion VND in land use fees |
| Jun 26, 2026 | Lotte and Phat Dat signed an investment cooperation agreement; total estimated capital of around 60,000 billion VND |
| Aug-Sep 2025 | Lotte Properties HCMC submitted a notice of contract termination for the project |
| Sep 2, 2022 | Groundbreaking ceremony; announced 5 basements, 60 above-ground floors, capital of roughly 20,100 billion VND |
| Jul 2017 | HCMC and Lotte signed the project implementation contract |
In 2022, Lotte set a completion target for 2028. Following the stagnation period, that milestone is no longer applicable. The only newly documented milestone is October 23, 2029, for blocks 2-1 and 2-3.
Phat Dat has completed the transfer of a 35% stake in Lotte Properties HCMC, the legal entity executing the project. For future buyers, this is a crucial detail to note: the progress of the residential blocks will depend on both partners.
Quick Answer: With 60 above-ground floors, the tallest tower in Lotte Eco Smart City is shorter than Landmark 81 (81 floors) and the Bitexco Financial Tower (68 floors). The distinction of the Lotte project lies not in a single record-breaking height, but in its complex of 11 mixed-use towers positioned right in the core of Thu Thiem, directly facing District 1.
| Building | Above-ground Floors | Status (Oct 2026) |
|---|---|---|
| Landmark 81 (Binh Thanh Dist.) | 81 | Operational |
| Empire 88 Tower (Empire City, Thu Thiem) | 88 (planned) | Under development |
| Bitexco Financial Tower (District 1) | 68 | Operational |
| 60-story Tower, Lotte Eco Smart City | 60 | Not yet commenced individually |
The floor counts for Landmark 81 and Bitexco are widely known figures. The 88-floor metric for Empire 88 is based on the Empire City rendering and master plan, and actual progress needs verification. I have not converted Lotte's height into meters as there is no official number yet.
Regarding location, the project is situated in Functional Area 2A: bordered by the Central Square to the north, the Thu Thiem Tunnel entrance and Empire City to the south, the central lake to the east, and the Saigon River to the west. Simply put: as you exit the Thu Thiem Tunnel, you will see Lotte on one side and Empire City on the other.
Quick Answer: If you are a long-term investor and can tolerate the lack of pricing and handover schedules, Lotte Eco Smart City is worth monitoring due to its prime Thu Thiem core location. If you need a home to live in or rent out within the next 1–3 years, you should look at the completed projects right next door.
To be straightforward, here are a few things you should know before lining up to wait:
The bright side is equally clear: once this office and commercial complex becomes operational, the entire core of Thu Thiem will see an influx of working professionals. Completed apartment projects nearby, such as Empire City right across the street, will be the first to benefit from the rental demand.
Achieve Realty VN operates daily in the Thu Thiem core area: Empire City (Linden, Tilia, Cove, Narra), Metropole Thu Thiem, The River, and Zeit River.
