59 Heritage Sukhumvit (59 เฮอร์ริเทจ สุขุมวิท)

59 Heritage Sukhumvit is a high-rise condominium located at 18 Khlong Tan Nuea, Watthana, Bangkok 10110, in Sukhumvit 59. The project sits in a prime inner Sukhumvit neighborhood with convenient access to Thong Lo and Ekkamai. It is approximately 500 meters from BTS Thong Lo, making it suitable for both residential living and rental investment.

The project was developed by Thai Factory Development Public Company Limited and completed in 2009. It is a 27-storey condominium with 1 building and around 226 residential units. Parking is provided in a proportion appropriate for an upper-mid to luxury urban condominium. Unit types include 1-bedroom, 2-bedroom, 3-bedroom, and penthouse layouts, catering to both end-users and buyers seeking larger units in central Sukhumvit.

Facilities include a swimming pool, fitness center, sauna, garden, lobby, passenger elevators, and common areas designed for daily convenience. Security features include 24-hour security guards, CCTV, and key card access. The property is generally managed under a juristic person system responsible for common area maintenance and resident services.

A key strength of the project is its relatively private atmosphere despite being in a central location. Nearby amenities include EmQuartier, Emporium, Gateway Ekkamai, international dining options, and leading hospitals. This makes the project appealing for buyers looking for a condo near mass transit in an area with strong rental demand. A nearby project in the same zone is Ivy Thonglor.

59 Heritage Sukhumvit (Thonglor-Ekkamai area) in 2026 shows a steady resale market supported by expat and professional rental demand. With BTS Thong Lo about 450 m away, leasing liquidity remains relatively strong, although newer projects nearby keep pricing competitive.

• Resale price per unit: 1-bedroom 45 sq.m. averages THB 6.8M
• Price per sq.m.: around THB 150,000 (typical range THB 135,000-170,000 depending on condition, floor, and renovation)
• Average rent: THB 28,000 per month for a furnished 1-bedroom 45 sq.m.

Rental Yield (2026): THB 28,000 x 12 = THB 336,000 per year. Against a THB 6,800,000 purchase price, gross yield is about 4.9% p.a. (336,000 ÷ 6,800,000). Net yield will be lower after common fees, vacancy, and agent costs, so investors should underwrite conservatively.

Capital Gain outlook: As an established condo near Thonglor, upside is likely moderate rather than aggressive. With new launches often priced higher, well-maintained units can still appreciate. A reasonable base case is 2-4% p.a.; over a 3-year holding period, that implies roughly 6-12% price growth before transaction expenses.
