NIA by Sansiri

NIA by Sansiri is a High Rise condominium located at 89 Phra Khanong Nuea, Watthana, Bangkok 10110, in the Sukhumvit 71 area near Ekkamai and Thonglor. The project is suitable for both residential living and rental investment. It was developed by Sansiri Public Company Limited and completed in 2023.

The project consists of 1 building with 19 floors and 520 residential units, with parking spaces for approximately 40% of total units. Room types include 1 Bedroom, 1 Bedroom Plus, and 2 Bedroom units. The layouts are designed for practical urban living with clearly separated functional spaces.

Facilities include a lobby, co-working space, swimming pool, fitness room, communal garden, relaxation areas, and multipurpose spaces. The security system features security personnel, CCTV, key card access, and controlled entry points.

The project is located about 1.3 km from BTS Phra Khanong Station and about 1.8 km from BTS Ekkamai Station. Nearby landmarks include W District, Gateway Ekkamai, Major Cineplex Sukhumvit, Sukhumvit Hospital, and several international schools. Property management follows Sansiri standards, known for service quality and common area maintenance. A nearby project of interest is Ivy Thonglor.

NIA by Sansiri is in Phra Khanong Nuea, Watthana, benefiting from the Ekkamai-Thonglor catchment. In practical terms, the nearest BTS Sukhumvit Line stations are BTS Phra Khanong at about 1.2 km and BTS Ekkamai at about 1.6 km. In 2026, the resale market here competes with nearby projects such as Siri at Sukhumvit and Thru Thonglor, so price growth tends to be steady rather than aggressive, while rental demand is supported by office workers and expatriates.

• Resale price per unit (2026): 1-bedroom, 30 sq.m. averages THB 4.65M
• Price per sq.m.: about THB 155,000/sq.m. (commonly seen range THB 145,000-170,000)
• Average rent: about THB 20,000/month for a 30 sq.m. 1-bedroom

Rental Yield (simple calculation): annual rent THB 20,000 x 12 = THB 240,000. Divide by purchase price THB 4,650,000 = 0.0516, or roughly 5.2% per year (before common fees, tax, and vacancy). This is relatively attractive versus prime Thonglor where yields are often lower.

Capital Gain outlook: assuming a realistic 3-5% annual appreciation for mid-to-east Sukhumvit, THB 155,000/sq.m. could edge up to around THB 160,000-165,000/sq.m. over the next 12 months. For a 30 sq.m. unit, that implies a potential gain of roughly THB 150,000-300,000. Key risk is the sizable rental supply around Phra Khanong-Ekkamai, meaning rent increases depend on unit condition, furnishing, and pricing discipline.
