Overview
HQ Thonglor is a luxury high-rise condominium that embodies the concept of "Jewel of Thonglor." Completed in 2014 by Sansiri, this 36-storey tower is recognized for its sleek architectural profile and high-spec marble finishes. With only 197 units, it offers a high degree of privacy and exclusivity in one of Bangkok's most vibrant and densely populated lifestyle districts.
The project is famous for its central location on the "even" side of Thonglor, sitting directly between Soi 4 and Soi 6. This placement puts residents within a 2-minute walk of major landmarks like Eight Thonglor and Marketplace Thonglor. In 2026, HQ Thonglor remains a flagship asset for Sansiri, known for its timeless design, 2.7-meter ceiling heights, and a well-curated facility deck on the 10th floor that offers a peaceful escape from the bustling street below.
Developer
Sansiri Public Company Limited is one of Thailand's most prominent luxury developers.

The building is professionally managed by Plus Property (a Sansiri subsidiary), with a current common area fee (CAM) of 55 THB/sqm, ensuring the lobby and facilities maintain their high-end appeal.
