THE BASE Urban Rama 9

THE BASE Urban Rama 9 is a high-rise condominium located in Huai Khwang Subdistrict, Huai Khwang District, Bangkok 10310. The project sits in the Rama 9 - Ratchada area, a well-known new CBD zone with convenient access to Rama 9 Road, Ratchadaphisek Road, and Si Rat Expressway. It is approximately 1.6 kilometers from MRT Phra Ram 9 Station and around 1.7 kilometers from MRT Thailand Cultural Centre Station.

Developed by Sansiri Public Company Limited and completed in 2014, the project consists of 1 residential tower with 35 floors and about 639 units. Parking is available for approximately 40% of total units. Room types mainly include 1-bedroom and 2-bedroom layouts, with sizes starting from around 26 - 52 square meters. This makes the project suitable for both owner-occupiers and investors seeking rental demand in the Rama 9 area.

Facilities include a swimming pool, fitness room, garden, lobby, multipurpose room, and common areas designed for urban living. The security system includes 24-hour security guards, CCTV, key card access, and controlled entry points. Project management follows Sansiri standards, which are generally recognized for strong common area maintenance and long-term residential quality.

Nearby landmarks include Central Rama 9, Fortune Town, and Esplanade Ratchada, supporting both daily convenience and investment potential. For a nearby project, please see Atmoz Ratchada-Huaikwang

THE BASE Urban Rama 9 in 2026 shows a steady but not aggressive resale market. Demand is supported by office workers around Rama 9-Ratchada and renters who want a mid-range condo, while the area’s ongoing supply keeps pricing sensitive to unit condition, floor level, and furnishing quality.

• Resale price per unit (1-bedroom 26-30 sq.m.): about THB 3.10-3.60 million
• Average price per sq.m.: roughly THB 115,000-135,000 (high floors and fully furnished units tend to achieve the upper band)
• Average rent: Studio THB 12,000-14,000 per month, 1-bedroom THB 15,000-18,000 per month

Rental Yield example (simple gross yield, excluding common fees and taxes): buy a 1-bedroom 28 sq.m. at THB 3.30 million and rent at THB 16,500 per month. Annual rent = 16,500 x 12 = THB 198,000. Gross yield = 198,000 - 3,300,000 = 6.0% per year. In practice, achievable gross yields are commonly around 5.0-6.2% with stable occupancy.

Capital gain outlook: based on typical 2-4% annual growth for mid-market condos in the Ratchada-Huai Khwang zone under normal conditions, a THB 3.30 million unit could move to about THB 3.50-3.70 million over 2-3 years (around 2-12% upside). However, nearby competing projects such as Atmoz Ratchada-Huaikwang and The Excel Ladprao-Sutthisan may pressure both resale pricing and rents during high-supply periods.
