Overview
98 Wireless is widely considered the flagship of Thai luxury real estate. Developed by Sansiri PCL and completed in 2017, it sits on one of the very last freehold plots on the prestigious Wireless Road.
With only 77 units across 25 floors, it offers an exclusivity that few other projects can match. The building is designed in a Beaux-Arts style, distinct from the modern glass towers of Bangkok, and features common areas exclusively styled by Ralph Lauren Home. It is often cited as the most expensive condominium in Thailand by price per square meter.
Developer
Sansiri Public Company Limited is a top-tier Thai developer known for lifestyle-driven projects. 98 Wireless was their "magnum opus," created to set a new benchmark for quality (using imported limestone from Portugal and marble from Italy) and service (partnering with Quintessentially).

Pros
- True Freehold — A rarity on Wireless Road, where most land is Crown Property leasehold.
- Ultra-Exclusivity — Only 77 units ensure extreme privacy.
- Timeless Design — The Beaux-Arts architecture and Ralph Lauren interiors will age better than "trendy" modern designs.
- Service Level — The combination of Butler, Valet, and Concierge services is hotel-standard.
- Pet Friendly — One of the few Super Luxury buildings that officially permits pets (small size).
Cons
- Price — It is arguably the most expensive condo in Bangkok; rental yields are generally lower (approx 2-3%) because the asset price is so high.
- Traffic — Wireless Road can become gridlocked during rush hour, though being close to the BTS helps.
- No Small Units — The smallest unit is ~120 sqm; there are no "entry-level" options.
Best For
- Ultra-High-Net-Worth Individuals (UHNWI) — Collectors of "trophy assets."
- Diplomats & CEOs — Who require high security, privacy, and proximity to embassies/offices.
- Pet Lovers with Budget — Who want luxury living without compromising on their furry companions.
The Bottom Line
98 Wireless is not just a condo; it is a statement of wealth and taste. It is the "One Hyde Park" of Bangkok. If budget is no object and you seek a freehold asset that competes on a global stage for quality and prestige, this is the only address that matters in 2026.
