Overview
Baan Siri Silom is a high-rise boutique condominium that epitomizes the "Sansiri Heritage" of the mid-2000s. Completed in 2006, it remains one of the most respected residential addresses on Si Wiang Road, a quiet, leafy street that connects the bustling Silom and Sathorn districts.
Unlike the mega-towers of modern Bangkok, Baan Siri Silom offers an intimate living environment with only 137 units. Its architecture is a blend of Asian-modern aesthetics and functional urban design. Because of its location in a residential pocket near top-tier schools like Bangkok Christian College, it is a perennial favorite for families and expats who want CBD proximity without the direct noise of the main road.
Developer
Sansiri Public Company Limited is one of Thailand's most prominent developers, known for high construction standards and long-term property management. Baan Siri Silom was part of their early "Baan Siri" series, which focused on boutique, high-end living. Even in 2026, the building is noted for its excellent maintenance and structural integrity.

Pros
- Exclusivity — Only 137 units ensures a quiet, private atmosphere.

- Unit Size — Excellent value for square footage; 1-bedroom units here are the size of modern 2-bedroom units.
- Management — Plus Property (Sansiri's management arm) has kept the building in top condition for two decades.
Cons
- Building Age — Completed in 2006; while well-maintained, the lobby and exterior design reflect a mid-2000s style rather than 2026 ultra-modernism.
- No Pet Policy — Unlike some newer Sansiri projects, this building strictly prohibits pets.
- Price Per Sqm — While cheaper than brand-new neighbors like Tait 12, the entry price is still high due to the large unit sizes.
Best For
- Parents of BCC Students — The proximity to Bangkok Christian College is the primary driver for local buyers.
- Long-stay Expats — Who work in the Sathorn financial district but prefer a quiet residential street.
- Value-Luxury Seekers — Who want a "Sansiri standard" building without paying the "brand new" price premium.
The Bottom Line
In 2026, Baan Siri Silom remains a "Blue Chip" investment in the Bang Rak district. It offers a sense of stability and community that is often lost in larger, newer projects. For those who prioritize space, school proximity, and a quiet neighborhood vibe, Baan Siri Silom is a top-tier choice that holds its value year after year.
