The project sits in the Sathorn - Naradhiwas area, a prime business district with convenient access to the city. It is approximately 600 meters from BTS Chong Nonsi Station and about 200 meters from BRT Arkhan Songkhro Station, making it suitable for both urban living and investment.

Developed by Origin Property Public Company Limited, the project was completed in 2019. It consists of 1 residential building with 43 floors, 726 residential units, and 1 retail unit. Parking is available for approximately 344 cars, or around 47 percent of total units. The project stands out for its high-ceiling room concept and well-designed common areas that match modern city lifestyles.

Unit types include 1 Bedroom, 1 Bedroom Plus, 2 Bedrooms, and Vertiplex units, which offer high ceilings and a layout similar to a duplex style. Unit sizes range from approximately 22 - 55 square meters, depending on room type.

KnightsBridge Prime Sathorn (Thung Maha Mek-Sathorn) shows a more stable resale market in 2026 after the earlier rebound, supported by rental demand from Sathorn-Silom office workers and long-stay expatriates seeking CBD proximity. The project is about 1.6 km from BTS Chong Nonsi and around 1.7 km from MRT Lumphini, making it more suitable for tenants who commute by car or ride-hailing.

• Resale price per unit (1-bed 30-33 sq.m.): THB 4.9-5.8M
• Average resale price: THB 165,000-185,000 per sq.m. (well-kept units, open view)
• Average rent: THB 22,000-28,000 per month (1-bed), THB 16,000-19,000 per month (studio)

Rental Yield example (2026): Buy at THB 5.30M, rent at THB 25,000 per month = THB 300,000 per year. Gross yield = 300,000 ÷ 5,300,000 = 5.66% (before common fees, maintenance, and vacancy).

Capital gain outlook: Using a 2024-2025 reference range of roughly THB 155,000-170,000 per sq.m., an increase to THB 165,000-185,000 per sq.m. implies about 3-8% growth over 12-24 months. For 2026, upside is likely moderate due to strong competing supply across Sathorn-Rama 4. Investors should prioritize high-floor, better-view units and price rents tightly to market to protect occupancy.
