St. Louis Grand Terrace

St. Louis Grand Terrace is a high-rise condominium located in Yan Nawa, Sathon, Bangkok 10120, near the Sathorn - Naradhiwas intersection. The project is approximately 1.2 kilometers from BTS Surasak Station, offering convenient access to Sathorn, Silom, and Rama 3, making it suitable for both residential living and rental demand.

The project was completed in 2006 and developed by St. Louis Grand Terrace Co., Ltd. It consists of 1 residential building with 28 floors and around 245 units. Parking is available for residents. Unit types include 1-bedroom, 2-bedroom, and larger family-size layouts, with relatively spacious usable areas compared with many condominiums in the surrounding area.

Facilities include a swimming pool, fitness room, garden, passenger elevators, and common areas for daily living. The security system includes 24-hour security guards, key card access, and CCTV cameras.

From a market perspective, this project stands out for its larger unit sizes and established Sathon location. It is more suitable for buyers seeking a residence for actual living than for short-term speculative investment. The project is also close to Saint Louis Hospital, Assumption Commercial College, and many office buildings. For comparison with another condominium project in Bangkok, see Bangkok Feliz Krungthonburi Station.

Saint Louis Grand Terrace (Yan Nawa-Sathon) shows a steady, not overheated, market in 2026. Demand is supported by renters working in the CBD (Sathon-Silom), while nearby high-end projects such as ROMM Convent and Chidlom-area condos help set a higher price benchmark. Overall, pricing moves gradually and remains sensitive to unit condition and view.

• Resale price per unit: 1-bed 45 sq.m. averages THB 5.2M (range THB 4.8-5.6M)
• Resale price per sq.m.: avg THB 115,000 (range THB 105,000-125,000)
• Average rent: THB 22,000 per month (range THB 20,000-25,000)

Rental Yield (quick math): annual rent THB 22,000 x 12 = THB 264,000. Yield = 264,000 / 5,200,000 = 0.0508, or about 5.1% per year (before common fees and taxes). This level is attractive for investors prioritizing cashflow in a prime Sathon zone.

Capital gain outlook: using a conservative 2-4% yearly growth assumption for Sathon, the average price could edge up to roughly THB 117,000-120,000 per sq.m. over the next 12 months. Upside tends to concentrate in renovated units, higher floors, and layouts that rent quickly, while older-condition units may require pricing discounts to compete.
