Located adjacent to the lush Lumphini Park, it offers unparalleled connectivity and a vibrant urban atmosphere. Featuring Grade A+ office spaces designed with a future-proof philosophy, the project boasts world-class smart systems and Platinum-level digital connectivity.
In this article, we invite you to explore the world of One Bangkok.

One Bangkok, the premier landmark in the heart of the Rama IV district, has announced the latest progress of its office zone to meet the growing demand for Grade A+ office space in Bangkok’s Central Business District (CBD).
Currently, Towers 3, 4, and 5 are officially open. These towers represent the pinnacle of Smart City Office design, featuring cutting-edge building management technology and world-class sustainability standards. Leading multinational corporations have already begun operations within these spaces.
Looking ahead, the project is set to expand further with the launch of Tower 2 in Q3 2026. Upon completion, One Bangkok will solidify its position as one of the largest and most advanced integrated business hubs in Thailand.
As a leader in digital and sustainable infrastructure, the building achieved WiredScore Platinum rating and is currently on track to achieve SmartScore alongside LEED Neighborhood Development and WELL Platinum certifications.
Situated in a prime CBD location bordering Lumphini Park, One Bangkok offers a prestigious CBD address with seamless access to Silom and Sukhumvit. The project is surrounded by key diplomatic missions, including the Japanese, Australian, and U.S. Embassies, making it a strategic hub for global business.
MRT Lumphini provides direct access to One Bangkok via a sheltered passageway from Exit 1, ensuring a seamless, rain-free commute.
Located just three stops from the MRT Sukhumvit/BTS Asoke Interchange, the project offers effortless connectivity to Sukhumvit and all major areas across Bangkok.
For added convenience, a complimentary shuttle bus runs every 15 minutes between 7:00 and 22:00, connecting One Bangkok Tower 4 (G Floor) to BTS Phloen Chit Station.
Additionally, regular electric cart services are available for seamless transit between the towers within the project.
The entrance features a sleek, futuristic design with a staffed reception and smart security gates.
A secure visitor management system requires ID registration for an access QR code, while controlled elevator access ensures transit only to authorized floors for maximum security.
The building’s elevator system features a modern design, divided into four zones to ensure efficient service:
High Zone: Serves the high 9 floors.
Middle High Zone: Serves the middle-high 9 floors.
Middle Low Zone: Serves the middle-low 9 floors.
Low Zone: Serves the low 10 floors.
The building is equipped with a total of 24 elevators (12 for the upper zones and 12 for the lower zones) to minimize wait times and accommodate a high volume of users.
The office spaces are intelligently designed to maximize efficiency, featuring highly functional layouts without obstructive columns or wasted space.
With a generous 3-meter ceiling height, the interiors offer a spacious and premium atmosphere for a superior working environment.

West-facing units offer panoramic views of Lumphini Park, while south-facing units overlook the project’s central area.
As views vary by floor and orientation, we recommend a site visit to select the perspective that best suits your preference.


The restrooms are impeccably maintained, offering a luxurious, hotel-like ambiance.
For added convenience, multipurpose restrooms are equipped with shower facilities, providing a refreshing option perfect for Thailand’s tropical climate.
Shared pantry rooms are also provided on each floor for the convenience of tenants.
The designated smoking area is located outdoors on the G floor, positioned a short distance from the main office entrance.
The B1 floor features an array of now-open retail options, including cafés, convenience stores, and diverse dining. As the remaining towers reach completion, the selection will continue to expand with even more world-class tenants.
The food court is also now open, providing a wide variety of convenient dining options for office workers and visitors
The retail experience is divided into three distinct zones: The PARADE, THE STOREYS, and POST 1928. This is complemented by a premium 4,600 sq.m. Mitsukoshi Isetan Holdings supermarket.
Additionally, a world-class Convention Center is currently under development to host major international events and business activities.
One Bangkok features five luxury hotels, headlined by world-class brands such as The Ritz-Carlton and Andaz. To complete this ‘integrated district’ experience, three premium residential towers offer sophisticated urban living for business leaders and residents who seek a seamless balance of work, life, and leisure in the heart of the CBD
That’s conclude our introduction to One Bangkok.
With its seamless integration of smart office spaces and a world-class lifestyle, One Bangkok is more than just a workplace—it is a landmark of the future, designed to elevate both professional excellence and quality of life
