T-One Building — The Newest and Only Grade A Office Tower in Thonglor, Built Around the “Work Hard, Play Harder” Concept

  
When people think of Thonglor, many immediately picture one of Bangkok’s most vibrant lifestyle districts—filled with trendy venues, luxury residences, award-winning restaurants, stylish cafés, and a neighborhood that remains lively from day to night. From an office market perspective, Thonglor has also developed its own unique identity and continues to grow in popularity among businesses seeking a more premium and lifestyle-driven workplace environment. This can be clearly seen in the consistently strong occupancy rates of office buildings throughout the area, including Major Tower, Home Place Building, and even Bangkok Business Center—all of which continue to attract strong tenant demand.

One of the reasons Thonglor continues to attract businesses is that its image feels professional, yet not overly rigid or overly corporate.As a result, companies that intentionally choose this location often come from industries that value creativity, innovation, and independent thinking—such as fashion brands, advertising agencies, food and beverage businesses, startups, creative studios, and coworking operators. That said, it is no longer unusual to see highly corporate and traditionally formal businesses embracing the Phrom Phong–Thonglor corridor as well. This is clearly reflected by the exceptionally high occupancy rates in landmark office buildings such as Bhiraj @ EmQuartier and Emporium Tower, both of which have remained close to fully occupied.

In 2018, Thonglor welcomed a new landmark—its first and only Grade A office tower.

T-One Building is a 34-story Grade A office tower offering approximately 22,500 square meters of leasable office space. The building is strategically located on Sukhumvit Road, at the entrance of Sukhumvit Soi 40, which also provides convenient connectivity to Rama IV Road. The surrounding neighborhood is filled with premium lifestyle destinations, including Major Cineplex Ekkamai, Emporium, and EmQuartier—all located just one BTS station away—while Bangkok Marriott Hotel Sukhumvit is situated directly across from the building, further enhancing the convenience and prestige of the location.

As for the building itself, T-One Building offers the full range of facilities and conveniences expected from a modern Grade A office tower, including:

• Direct connectivity to BTS Thong Lo Station via a dedicated Skywalk that connects the station directly to the building’s second floor.

  The walking distance from the station is approximately 300 meters, or roughly 3 minutes on foot, providing exceptional commuting convenience for both employees and visitors.

• A highly distinctive architectural design that breaks away from the monotony of conventional box-shaped office towers, while still maintaining highly efficient and practical floor layouts for modern business operations.

• Dedicated coworking space designed to support modern businesses, startups, entrepreneurs, and freelancers looking for a collaborative environment where ideas, networking, and creativity can naturally come together.

• Automated Car Parking System with capacity for approximately 368 vehicles, making T-One one of the early office buildings in Bangkok to adopt this advanced parking technology at scale.

• Premium building specifications throughout, including:

  • 3-meter floor-to-ceiling height
  • Central Chilled Water Air-Conditioning System
  • 24-hour chilled water supply, ideal for tenants operating server rooms or mission-critical IT infrastructure
  • Other Grade A technical specifications designed for modern corporate occupiers

• Pre-planned internal staircase provisions for larger tenants who wish to connect multiple leased floors with private staircases (subject to additional fit-out costs and landlord approval).

• Retail spaces located on Levels 1 and 2, along with a potential rooftop restaurant concept (subject to final confirmation by the building owner).
