Siamese Thirty Nine Sukhumvit 39

Siamese Thirty Nine Sukhumvit 39 is a high-rise condominium located on Sukhumvit 39, Khlong Tan Nuea, Watthana, Bangkok 10110. Positioned in the Phrom Phong area, the project offers convenient access to Sukhumvit Road, Phetchaburi Road, and Thonglor. It is approximately 1.3 kilometers from BTS Phrom Phong, making it suitable for both residence and investment in one of Bangkok's strong rental demand zones.

The project was developed by Siamese Asset Public Company Limited. It comprises 1 residential building with 7 floors and around 87 units. Parking is provided according to the project allocation. The development was completed around 2013. Unit types include 1-bedroom, 2-bedroom, and penthouse layouts, with relatively spacious living areas compared with many inner Sukhumvit condominiums.

Facilities include a swimming pool, fitness center, garden, passenger elevators, and common area spaces for daily use. Security features include 24-hour security guards, CCTV, and key card access control. Property management is handled through the condominium juristic person, responsible for maintaining common areas and resident services.

A key advantage of the project is its privacy, supported by a relatively low-density unit count, while remaining close to major lifestyle destinations such as EmQuartier, Emporium, Samitivej Sukhumvit Hospital, and several international schools.

Siamese Thirty Nine Sukhumvit 39 in 2026 sits in the Phrom Phong-Thonglor pocket where demand is driven by expats and CBD professionals. With nearby competitors such as Ivy Thonglor and Culture Thonglor, pricing tends to move in a “steady” pattern rather than sharp spikes, and liquidity depends heavily on unit size and view.

• Resale price per unit: 1-bedroom 32 sq.m. averages THB 6.4M
• Resale price per sq.m.: about THB 200,000 per sq.m. (typical range THB 185,000-220,000)
• Average rent: THB 28,000 per month for 1-bedroom 30-35 sq.m.

Rental Yield (2026): quick method (annual rent ÷ purchase price) = (28,000 x 12) ÷ 6,400,000 = 336,000 ÷ 6,400,000 = 5.25% per year (before common fees and taxes).

Capital Gain outlook: Using a conservative inner-Sukhumvit growth band of 2-4% per year, this project’s realistic upside is around 2.5-3.5% annually, supported by stable long-stay rental demand and new supply launching at higher entry prices. For resale, mid-to-high floors with open views typically protect pricing and shorten time-on-market.
