The Room Sukhumvit 40

The Room Sukhumvit 40 is a high-rise condominium located at 9 Soi Saman Chan, Phra Khanong Subdistrict, Khlong Toei District, Bangkok 10110. The project sits in the Sukhumvit inner-city zone between Ekkamai and Phra Khanong, around 850 meters from BTS Ekkamai and about 900 meters from BTS Phra Khanong, making it suitable for both residential living and rental investment.

The project was developed by Land and Houses Public Company Limited and completed in 2012. It is a residential condominium with 1 building, 8 floors, and approximately 128 units, with parking for around 70 cars. Unit types include 1-bedroom, 2-bedroom, and penthouse layouts, with usable space starting from about 42 square meters. One of its key strengths is a relatively private atmosphere with low unit density compared with many projects in central Sukhumvit.

Facilities include a swimming pool, fitness room, steam room, garden, lobby, and passenger elevators. The security system features 24-hour security guards, CCTV, and key card access. Project management is handled in an organized manner in line with premium condominium standards associated with the developer.

The surrounding area offers convenient access to Sukhumvit 40, Sukhumvit Road, and Rama 4 Road. Nearby landmarks include Gateway Ekkamai, Major Cineplex Sukhumvit, Sukhumvit Hospital, and the lifestyle hubs of Thonglor and Ekkamai.

The Room Sukhumvit 40 in 2026 remains supported by its Ekkamai-Thonglor Sukhumvit-side positioning. Demand is driven by office workers and expats who prefer a quieter residential lane while staying close to the CBD. The project is about 1.2 km from BTS Ekkamai and around 1.4 km from BTS Thong Lo, which helps keep rents resilient even as new supply enters the wider area.

• Resale price per unit: 1-bed 45 sq.m. averages THB 7.2 million
• Average price per sq.m.: ~THB 160,000 (typical range THB 145,000-175,000 depending on condition and view)
• Average rent: THB 30,000 per month for a 45 sq.m. 1-bed (often THB 28,000-35,000)

Rental Yield (quick math): 30,000 x 12 = THB 360,000 per year; Yield = 360,000 ÷ 7,200,000 = 0.05, or about 5.0% gross per year (before common fees and taxes). This is relatively attractive versus prime Thonglor projects where higher entry prices often compress yields.

Capital Gain: Using a conservative 2-4% annual appreciation from a THB 160,000 per sq.m. base implies a next-year level around THB 163,000-166,000 per sq.m. Key downside risk is competition from newer condos along Ekkamai-Thonglor that can pull tenants. The project’s advantage is Sukhumvit 40’s calmer micro-location and stable end-user demand, supporting gradual price growth rather than sharp spikes.
