Overview
Condo One X Sukhumvit 26 is a well-established high-rise condominium situated in the heart of the Phrom Phong district. Completed in 2008 by Plus Property (part of the Sansiri group), this 28-story building has aged gracefully, maintaining its reputation as a reliable and value-oriented residential choice in a high-demand neighborhood.
The project is designed with an emphasis on space efficiency and ventilation. It features large windows that reach toward the ceiling, allowing for significant natural light—a design trait that makes even the smaller studio units feel airy. While it is an older development, its prime location on Soi 26—a leafy, upscale residential street—keeps it highly competitive for both rental and resale markets, especially among Japanese expatriates who favor the Phrom Phong area.
Developer
Plus Property Partner, the development arm of the renowned Sansiri PCL, is the developer behind this project. Plus Property is widely known for its expertise in property management and building services, which is reflected in the solid upkeep of Condo One X. The building's juristic team is often praised for maintaining the facilities and security to a modern standard, with common area fees typically hovering around 40 THB/sqm.
Location & Transit

|---|---|---|---|
| BTS Phrom Phong | Sukhumvit | 700m | Walk (9 min) |

Commute Logistics:
- Walking Distance: The condo is roughly a 10-minute walk from BTS Phrom Phong, which provides direct access to the Sukhumvit artery.
- Rama IV Access: Soi Sukhumvit 26 is one of the few streets that directly connects Sukhumvit Road to Rama IV Road, offering drivers a strategic advantage for reaching the Silom/Sathorn CBD.
- Local Amenities: The building sits in a "quieter" pocket of Soi 26 but is only minutes away from the vibrant Emporium/EmQuartier shopping hub and numerous high-end Japanese restaurants.
