189 Wireless Road. Lumphini Park across the road.
At the Wireless and Rama IV junction. Inside the One Bangkok masterplan. Adjacent to EI8HTEEN SEVEN.
About the boulevard
The address is 189 Wireless Road, at the intersection with Rama IV, inside the One Bangkok masterplan. Wireless Road is Bangkok's diplomatic mile, taking its name from the radio station that once broadcast from here in the early twentieth century. Today it carries the embassies of the United States, the United Kingdom, the Netherlands, Switzerland, Indonesia, and Vietnam, alongside Bangkok's most institutional residential addresses, shaded by mature rain trees.
ONE89 sits at the southern entrance to the boulevard, adjacent to EI8HTEEN SEVEN. Lumphini Park is directly across Wireless Road to the west: 142 acres, Bangkok's primary green anchor, with views from the upper floors across the lake and canopy toward the Sukhumvit skyline. The Green Corridor skywalk connects Lumphini directly to Benjakitti Park.
On the Lumphini park-axis.
Six streets, four sub-markets, and one 142-acre park they all answer to.
- The parkLumphini Park is 142 acres in the middle of the city, and the corridor is named for it: the six streets around it are priced by how directly they face it.
- The streetsWireless, Langsuan, Ratchadamri, Sarasin, Chidlom and Ploenchit, and Upper Sathorn. Each trades differently, and the corridor guide takes them one at a time.
- What tradesThe densest cluster of freehold branded residences in Bangkok sits on this axis, on land where most sites are held on long lease.
Lumphini park-axisExplore the Lumphini guide Leasehold on institutional land.
Most of central Bangkok's ultra-prime land is held by institutional landowners and offered on long-term lease. ONE89 Wireless sits inside that structure within One Bangkok. For many buyers here, that is not a step down from freehold, but a different, and often better-priced, way into the same address.
Past a few years, total rent paid overtakes what the lease cost.

Common questions.
What is ONE89 Wireless?
ONE89 Wireless is the flagship residential component of the One Bangkok masterplan, located at 189 Wireless Road at the intersection with Rama IV. It is a single residential tower with approximately 90 leasehold residences, the lowest residence count in the masterplan. ONE89 completed in 2025 and absorbed its launch inventory at that time. Today the building is available only through the resale and rental market. Architecture is understood to be by SOM (Skidmore, Owings & Merrill), to be confirmed. Developed through the TCC Assets and Frasers Property joint venture that delivers the broader One Bangkok masterplan. Embark Estate is the appointed sales and rental agency.
How does it compare to EI8HTEEN SEVEN?
The two buildings are adjacent inside One Bangkok and share the same corridor lifestyle; the differences are interior and structural rather than locational. ONE89 carries approximately 90 residences; EI8HTEEN SEVEN carries approximately 291. The choice is largely between residence density and the implied service ratio. ONE89 is positioned as the flagship residential address with the lowest residence count and the most concentrated service, available today only through resale and rental. EI8HTEEN SEVEN is a larger, more recently launched tower with current off-plan availability. Both are leasehold within the One Bangkok structure. Embark represents both buildings and walks each buyer through the comparison against their specific holding intent, family situation, and budget.
Is it freehold or leasehold?
Leasehold, on the institutional land structure that governs the One Bangkok masterplan. For foreign buyers, leasehold residences are accessible without the 49% foreign-quota constraint that applies to freehold Thai condominium units; for some foreign buyers this simplifies the legal pathway. For buyers comparing leasehold tenure to freehold alternatives on the corridor, Upper House Residences Bangkok and 98 Wireless are the principal freehold options.
Can foreign buyers purchase?
Yes. Leasehold residences in Thailand are available to foreign buyers without the 49% foreign-quota constraint that applies to freehold condominium ownership. The lease structure is registered with the Land Office and the rights pass through standard succession provisions for the lease term. Embark walks foreign buyers through the legal pathway at inquiry, in coordination with the buyer's own legal counsel.
How do I buy if the building is sold out?
The building is sold out, so there is no developer sales channel. Today the inventory comes from owners reselling or letting their residences through the resale and rental market. Embark Estate is the appointed sales and rental agency, currently with several listings in each category. The relevant question for buyers is which agent holds the specific listing that fits the brief.
Is it an operator-branded residence?
No. ONE89 is the flagship residence inside the One Bangkok masterplan, with independent residence management trained to hotel-grade service standards and a concierge presence. The building does not carry an operator brand licence. For buyers seeking an operator-branded residence inside the same masterplan or elsewhere on the corridor, alternative options exist; Embark walks each buyer through the trade-offs at inquiry.
