About the tower

ONE89 is the flagship residential tower inside One Bangkok, at the southern entrance to Wireless Road, adjacent to EI8HTEEN SEVEN. With approximately 90 residences, it carries the lowest residence count in the masterplan and the most concentrated service ratio. Larger residences face Lumphini Park directly.

Residence management is independent, trained to hotel-grade service standards, with a concierge presence. The building completed in 2025 and absorbed its launch inventory; today it trades through the resale and rental market, where Embark is the appointed sales and rental agency.

Architecture is understood to be by SOM (Skidmore, Owings & Merrill); the interior designer and full design credits are confirmed once verified against developer materials.

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.

The neighbourhood

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.

05 · The tenure question

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.

What it costs to live here: holding the lease versus renting the same home (illustrative)

Past a few years, total rent paid overtakes what the lease cost.

Leasehold paid mostly up front, then largely service chargeRenting climbs every year, with nothing held at the end
Move-inYears held →
Lease term horizonBeyond most holds
The functional ownership horizon typically exceeds most buyers' holding periods. Specific term and commencement are confirmed against the lease documents at inquiry.
Entry pricingBelow freehold
Leasehold on this land typically prices below an equivalent freehold per square metre. The same One Bangkok address and service standard, at a lower cost to enter.
Resale marketScarce inventory
Leasehold resale on institutional land in central Bangkok has a stable buyer base, and ONE89's low residence count makes available inventory scarce.
Capital patternHolds early on
Leasehold capital values follow a predictable curve. The first decades hold value most reliably; shorter holds see less compression than multi-generational positions.
Foreign-buyer eligibilityNo 49% cap
Leasehold residences are accessible to foreign buyers without the 49% foreign-quota constraint that applies to freehold Thai condominium units.
Freehold alternativesIf you need title
Buyers prioritising freehold should consider Upper House Residences Bangkok or 98 Wireless, both on Wireless Road.

Disclaimer: Not investment advice, and not a forecast. Resale values and the lines shown above are illustrative and not guaranteed; they depend on market conditions, the specific residence, holding period, and timing. Tenure decisions also turn on capital structure, family situation, foreign-buyer status, and tax. Government fees and lease terms should be confirmed against the project's legal documents. Our advisory walks through each buyer's situation, alongside the buyer's own legal counsel, in the first conversation.

Common questions

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.
