Developed by Supalai Public Company Limited, the project was completed in 2018. It consists of 1 residential building with 36 floors and approximately 384 units, with around 255 parking spaces, or about 66% of total units.

Supalai Premier Si Phraya-Samyan in 2026 sits in a core CBD-education pocket near Silom-Sathorn and Samyan. This supports both resale liquidity and rental demand, although competition from other inner-city condos remains a key pricing constraint.

• Typical resale price per unit: THB 5.6-7.2M (1-bedroom, 34-45 sq.m.)
• Average selling price per sq.m.: ~THB 165,000-190,000 per sq.m.
• Average rent: THB 22,000-30,000 per month (1-bedroom) and THB 32,000-45,000 per month (2-bedroom)

Rental Yield example (gross): a 35 sq.m. 1-bedroom bought at THB 6.30M and rented at THB 25,000 per month generates THB 300,000 per year. Yield = 300,000 ÷ 6,300,000 = 4.76% p.a. (before common fees, taxes, and vacancy).

Capital gain outlook: if 2024 pricing averaged ~THB 155,000-175,000 per sq.m., moving to 2026 levels of ~THB 165,000-190,000 per sq.m. implies roughly 3-6% annual appreciation. The main upside is stable tenant demand from Silom-Sathorn office workers and Samyan-related education hubs; the main risk is oversupply and aggressive pricing from comparable projects nearby, making realistic exit pricing essential.
