One City Centre is Thailand’s tallest newly built Grade A office building, located across from Central Embassy and right next to the head office building of Bank of Ayudhya. It is directly connected to BTS Phloen Chit Station via a skywalk, allowing seamless access regardless of weather conditions. The project is a joint development between Mitsubishi Estate Group and major developer Raimon Land Public Company Limited. The office floors feature a rare column-free design, ensuring world-class quality and maximizing space efficiency.

One City Centre is strategically located across from Central Embassy, with the BTS line. The building benefits from its prestigious surroundings, offering views of the lush greenery from the Embassy of the United States of America.
The area is known for its quiet, high-end environment, featuring several embassies and luxury hotels, including the Hotel Okura, Park Hyatt, and Rosewood, making it a highly attractive address for international, particularly Japanese, business travelers.
Inside, tenants will find ultimate convenience with on-site amenities such as various restaurants, a food court, and a supermarket for daily needs.
With direct connection from BTS Phloen Chit Station Exit 5 via skywalk, you can access the building without worrying about the weather. The same skywalk also connects to Central Embassy and Central Chidlom, providing outstanding convenience.


One City Centre is recognized as the first multi-tenant building in Southeast Asia to earn both LEED Gold and Fitwel 2-Star certifications. These certifications reflect its strong emphasis on environmental sustainability and occupant health, aligning with the growing demand for workplaces designed to meet the needs of the post-COVID era.
*LEED (Leadership in Energy and Environmental Design)
LEED is an international standard by the U.S. Green Building Council that evaluates a building’s environmental performance. Global companies like Google, Microsoft, and Goldman Sachs prefer LEED-certified offices, and Japanese corporations increasingly adopt them for corporate branding.
*Fitwel
Fitwel, established in 2017 by the U.S. Centers for Disease Control and Prevention (CDC) and U.S. General Services Administration (GSA), evaluates how buildings support human health and well-being across 12 key criteria, helping create healthier work environments and promote occupant wellness.
The building offers flexible office spaces, with each floor spanning 1,300 sq.m. Rental units can be tailored to tenants’ needs, ranging from a compact 125 sq.m. to multi-floor large-scale spaces.
A key feature is the “column-free design”—a rarity in Thailand—which maximizes space efficiency and layout flexibility. The high ceilings, reaching 3 meters (with panels) or an impressive 4.5 meters (exposed), combined with floor-to-ceiling glass windows, provide an exceptional sense of openness and abundant natural light.
The common areas are equipped with advanced, health-focused systems, positioning the building as a pioneer for the New Normal era. These features include Hitachi’s contactless visitor management and smart lighting (which automatically adjusts illumination), alongside Mitsubishi Electric’s touchless elevators, ensuring smooth, safe, and efficient movement throughout the building.

Advanced security includes facial recognition and QR code entry, ensuring both safety and convenience.

As Thailand’s tallest office building, One City Centre offers spectacular, unobstructed panoramic views from its upper floors.
To the south, enjoy views of the expansive greenery of the Embassy of the United States of America, with higher floors offering vistas that stretch to Lumpini Park.
To the north, the building is strategically set back over 100 meters from Sukhumvit Road, creating a spacious atmosphere enhanced by a dedicated public green park at the front.

To fully support the modern hybrid work model, the building provides both coworking spaces and dedicated shared meeting rooms available for rental on demand. This flexibility allows companies to minimize their dedicated in-house meeting area, resulting in highly cost-efficient and adaptable office usage.
Beyond the convenience of restaurants and cafés on the 1st and 2nd floors, One City Centre offers elevated lifestyle experiences.


Beyond the expansive open lobby, the building reinforces its Grade A prestige through refined details: elevator halls and shared corridors on every floor are meticulously finished with premium tile. The development and management incorporate the extensive expertise of the Mitsubishi Estate Group, ensuring this is a flagship property built to world-class standards.

A separate elevator is also available for people with disabilities.


The building provides numerous conveniences, including popular Japanese restaurants serving soba, ramen, and sushi, which are highly valued by Japanese tenants. Additionally, a Lawson convenience store is located inside for all quick shopping needs.


The trending café Arabica Coffee has also opened here.
Arabica Coffee is a “Made in Japan” brand from Kyoto that has expanded globally, with its first Thai branch opening at Iconsiam.

A food court is located on the 1st floor, offering a variety of affordable meal options. This area typically bustles with office workers during the busy lunchtime period.
