ONE89 Wireless. The flagship residence.

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 one of the appointed sales and rental agencies.

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.

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.

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.

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 one of the appointed sales and rental agencies, currently with several listings in each category. The relevant question for buyers is which agent holds the specific listing that fits the brief.

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.
