The Bang Na area offers excellent access to the EEC industrial zone and Chachoengsao, where many Japanese companies have factories. It also provides convenient connections to four expressways: Expressway No.7, Expressway No.9, Burapha Withi Expressway, and Chalerm Maha Nakhon Expressway. In addition, it is only about 20 minutes from Suvarnabhumi International Airport, making it an outstanding location.
This time, we are pleased to introduce AIA East Gateway!

The building is situated on Bangna-Trad Road, a strategic location for Japanese companies with factories in the EEC and Chachoengsao. AIA East Gateway is about a 5-minute walk from the MRT Yellow Line Si Iam Station, but since it is relatively far from the familiar BTS Sukhumvit Line, access from there is mainly by car.
There’s also a new community mall being built right next door, which will offer more convenience in the near future.
Let’s take a look at the route from BTS Udom Suk Station, a familiar stop for many Japanese residents, with photos.
From Exit 5 of Udom Suk Station, you can easily find a taxi.
Compared to Sukhumvit Road, traffic on Bangna Road is usually much lighter, so you’ll rarely encounter congestion.
By taxi, it’s approximately a 10-minute ride with a fare of around 65 THB.
Upon entering, you are greeted by a staffed reception counter and a security gate. Visitors are required to present their ID cards at the counter to receive an access card. The high level of security provided, as the elevators are programmed to stop only at the registered floor.
The entrance lobby makes a stunning impression with its bold and stylish design, highlighted by a massive LED display that covers an entire wall. This creates a modern and visually striking welcome for visitors.
Office floors located from the 6th-33rd floor, divided into:
With total of 16 elevators, 8 serving the low-rise zone and 8 serving the high-rise zone, providing efficient vertical transportation and minimal waiting times.
AIA East Gateway provides a variety of unit sizes, all thoughtfully designed for efficiency. In contrast to some buildings where irregular shapes or poorly positioned columns can reduce usable space, this building ensures optimal layouts without compromising comfort.
The ceiling height is approximately 3 meters, creating an open and comfortable atmosphere. Each floor has a total area of over 2,000 square meters.

Light sensors automatically switch off when spaces are unoccupied. They are also installed in restrooms, supporting the building’s energy-saving and eco-friendly concept.
Each unit is equipped with dust detectors that monitor particulate matter, carbon monoxide, and PM2.5. Should pollutant levels increase, the central air system automatically introduces fresh air, providing a healthier indoor environment—a particularly valuable feature in Bangkok, where PM2.5 pollution is frequent.
The building’s windows are triple-glazed, minimizing external noise from the busy Bangna-Trad Road, which experiences frequent heavy truck traffic, thereby providing a quiet and productive workspace.
Due to a few high-rise building nearby, the office provides wide panoramic views of Bangkok, including Suvarnabhumi Airport and Rama IX Park on clear days.
Views vary by floor and direction, so it’s recommended to check during inspections.

The restrooms are meticulously maintained and feature a luxurious, hotel-like design.
Multipurpose restrooms are equipped with showers—an especially welcome facility in Thailand’s tropical climate.
Shared pantry rooms are also available. Each floor is equipped with drinking water purifiers, so there is no need for tenants to separately contract water dispensers.
The smoking area is located outside on the ground floor.
The building hosts several coffee shops, including Amazon Coffee.
The ground floor features a market zone open Monday to Friday, with stores rotating monthly, and 7-Eleven vending machines are conveniently located in the lobby.
Being a newly completed building, occupancy is currently limited. Nevertheless, additional shops and restaurants are anticipated to establish themselves in the future, enhancing the building’s appeal and activity.
The building’s food court will open on October 1, 2024, accommodating approximately 10 vendors and providing diverse dining choices. This allows tenants to conveniently access meals indoors, even during rainy weather.
A fully equipped fitness gym with professional-grade equipment is available for tenants. It is well-frequented by local fitness enthusiasts, even during weekday afternoons.
The 5th floor offers a sky garden adorned with abundant greenery, including a selection of herbs, reflecting a Thai-inspired design.
