Klass Siam

Klass Siam is located at 19 Kasemsan 2 Alley, Wang Mai, Pathum Wan, Bangkok 10330. This is a Low Rise condominium in the Siam area, developed by Klass Asset Co., Ltd. and completed in 2016. The project consists of 1 building, 8 floors, with approximately 79 residential units and parking spaces for around 40% of total units. It is suitable for urban residents seeking privacy in a central location.

Unit types include 1-bedroom, 2-bedroom, and penthouse layouts. The units are designed with practical living space, offering relatively generous sizes compared with many condominiums in the same neighborhood. Facilities include a swimming pool, fitness room, lobby, relaxing area, passenger lift, and parking area. The security system includes 24-hour security guards, key card access, CCTV, and controlled building entry.

The project’s key advantage is its location in Kasemsan 2, providing convenient access to Siam and Rama I Road. It is about 350 meters from BTS National Stadium and about 900 meters from BTS Siam. Nearby landmarks include MBK Center, Siam Discovery, Siam Center, Siam Paragon, Chulalongkorn University, and Police General Hospital. This makes the project attractive for both owner-occupiers and rental investors, especially office workers, students, and expatriates looking for a residence in Bangkok’s prime city center. Building management is handled under the condominium juristic person system.

Klass Siam (Kasemsan 2, Pathumwan) is a walkable CBD condo supported by rental demand from Siam- Chula and nearby office clusters. In 2026, resale pricing remains “inner-city firm”, broadly comparable to nearby projects such as Villa Rachatewi and, in some unit types, still below prime Chidlom stock like The Address Chidlom.

• Resale price per unit: 1-bedroom 33 sq.m. averages THB 6.8M
• Price per sq.m.: about THB 206,000 per sq.m. (6,800,000 - 33)
• Average rent: THB 25,000 per month for a 12-month lease

• 2026 Rental Yield: (25,000 x 12) - 6,800,000 = 4.41% p.a. (before common fees and taxes)
• Interpretation: This is typical for central Bangkok where liquidity and tenant quality often matter more than maximizing yield.

• Capital Gain: Using an estimated 2024 level near THB 195,000 per sq.m. versus 2026 at THB 206,000 per sq.m., the implied gain is about 5.6% over 2 years, or ~2.8% per year.
• Upside drivers: strong “walk-to-Siam” appeal and stable renter base (students, young professionals).
• Key risk: price growth can flatten if many owners list similar units simultaneously, increasing competition in resale.
