Project Concept

One89 Wireless is shaped by a “quiet inner-city” design idea that fits Wireless Road-Lumphini, an area defined by embassies, premium offices, and a calmer urban rhythm. The project therefore prioritizes privacy, a composed atmosphere, and understated elegance rather than showy styling.

Architecturally, it adopts a contemporary language with crisp lines and a slender massing strategy to open up city views and reduce visual heaviness. A neutral material palette-glass, grey tones, and earthy shades-helps the building feel timeless and easier to maintain as tastes change over time.

Planning emphasizes natural light and ventilation. Openings and shared spaces are positioned to catch daylight and prevailing breezes, while the arrival sequence is designed as a transition from the main road into a more residential mood. Lobby layers and landscape elements act as visual and acoustic buffers, supporting a sense of retreat in the middle of the city.

Interiors focus on practical living: efficient layouts, furniture-friendly proportions, and storage that suits everyday urban routines. From an investor’s perspective, the strength lies in its non-trendy, durable design direction, which typically appeals to long-stay tenants working around Ploenchit-Wireless and supports resale liquidity in a prime CBD pocket.

Project Highlights

One89 Wireless stands out for its premium Lumphini-Wireless Road address, a refined residential pocket surrounded by embassies and Grade-A offices. The area feels calmer than main roads, yet remains tightly connected to the Ploenchit-Chidlom CBD, making it attractive for both end-users and rental-focused investors targeting executives and expatriates.

  • Prime Wireless-Lumphini location near Lumphini Park and the Ploenchit-Chidlom business corridor, supporting steady leasing demand from high-income tenants.
  • Rail transit access with BTS Phloen Chit about 1.0 km away and BTS Chit Lom about 1.4 km, enabling convenient commuting to Siam, Asoke, and key office zones.
  • Expressway connectivity close to the Chaloem Maha Nakhon Expressway, Phloen Chit toll gate about 2.0 km, helping reduce drive time toward Rama 4, Sukhumvit, and the city’s eastern districts.
  • Lifestyle ecosystem near Central Embassy, Central Chidlom, and One Bangkok, covering dining, shopping, and business meetups.
  • Differentiation a more private Wireless Road setting while still within the CBD radius, supporting long-term value resilience compared with condos directly on the main transit frontage.

Description

One89 Wireless is a luxury high-rise condominium located at 189 Lumphini, Pathum Wan, Bangkok 10330, on Wireless Road in one of Bangkok’s most prestigious residential areas. The project is approximately 1.1 km from BTS Phloen Chit Station and around 1.2 km from BTS Nana Station, offering convenient access to the CBD while maintaining a high level of privacy.

Developed by Sansiri Public Company Limited, the project consists of 1 residential tower with 48 floors and approximately 118 residential units, with a high parking ratio for residents. The project was completed around 2024.

Security features include 24-hour security guards, CCTV, key card access, and controlled entry systems. Project management follows luxury residential standards under Sansiri’s professional management platform.

Price Trend

One89 Wireless sits in the Wireless-Lumphini pocket, supported by real rental demand from office workers and expats. It is about 900 m to BTS Phloen Chit and about 1.1 km to BTS Chit Lom. In 2026, pricing remains resilient versus nearby prime-area peers such as Noble Ploenchit, reflecting the CBD address and steady leasing depth.

  • Resale price per unit: 1-bed 45 sq.m. averages THB 12.6M
  • Price per sq.m.: around THB 280,000 (commonly THB 260,000-310,000 depending on floor and view)
  • Average rent: 45 sq.m. averages THB 48,000 per month (range THB 42,000-55,000)

2026 Rental Yield: simplified calculation THB 48,000 x 12 = THB 576,000 per year. Divide by THB 12,600,000 purchase price = 4.57% p.a. (before common fees, taxes, and vacancy). This fits investors seeking mid-level cashflow in a core CBD location.

Capital Gain view: using an indicative 2024 base near THB 260,000 per sq.m. rising to THB 280,000 in 2026 implies about 7.7% growth, or roughly 3-4% per year. Upside is driven by sustained tenant demand, while price acceleration is typically capped by broader market cycles and new supply around Phloen Chit.
