Circle Sukhumvit 31

Circle Sukhumvit 31 is a high-rise condominium located at 55 Sukhumvit 31, Khlong Tan Nuea, Watthana, Bangkok 10110, in the Phrom Phong - Asok area. The project offers convenient access to central Sukhumvit and is close to BTS Phrom Phong Station at about 1.7 km, BTS Asok Station at about 1.9 km, and MRT Sukhumvit Station at about 1.9 km.

The development consists of 1 residential tower with 30 floors and approximately 139 units. Parking is available for around 80 - 90 cars. Unit types include 1-bedroom, 2-bedroom, 3-bedroom, and penthouse layouts, with usable sizes starting from around 46 sq.m. This room mix supports both end-user living and rental investment in a prime residential district.

Facilities include a swimming pool, fitness center, sauna, garden, lobby, passenger lifts, and common areas designed for daily convenience. The security system includes 24-hour security staff, CCTV, and key card access control.

The project was completed around 2014, developed by Fragrant Property, and managed under a condominium juristic person structure. Its key appeal lies in its relatively private atmosphere compared with many central Bangkok condominiums, while still being close to EmQuartier, Emporium, Terminal 21, and Samitivej Sukhumvit Hospital. For a nearby project in a similar area, see Ivy Thonglor.

Circle Sukhumvit 31 sits in Sukhumvit Soi 31 (Watthana), a pocket favored by expats and office workers commuting between Asoke and Thonglor. In 2026, pricing is supported by resilient rental demand and limited new supply inside the soi. The project is about 1.1 km from BTS Phrom Phong and around 1.8 km from MRT Sukhumvit, which helps maintain liquidity in the resale market versus nearby Thonglor and Asoke condos.

• Resale price per unit (2026): 1-bedroom, 45 sq.m. averages THB 7.2M
• Average price: ~THB 160,000 per sq.m. (commonly seen range THB 145,000-175,000 per sq.m.)
• Average rent: ~THB 32,000 per month for a 45 sq.m. 1-bedroom

• Rental Yield (brief math): (32,000 x 12) minus 1 vacant month = THB 352,000 per year; Yield = 352,000 - 7,200,000 = 4.9% p.a. (before common fees and taxes)

Capital gain view: With constrained supply in Soi 31 and price benchmarks from nearby projects such as Ivy Thonglor and Culture Thonglor often trading at higher psqm, upside is realistic but gradual. Buying around THB 160,000 psqm and assuming 3-4% annual appreciation suggests a potential THB 175,000-185,000 psqm in three years, implying roughly 9-15% capital gain. Best risk-adjusted picks are well-kept units with open views and rents set close to actual market clearing levels.
