The Reserve Kasemsan 3

The Reserve Kasemsan 3 is a luxury low-rise condominium located at 8 Soi Kasemsan 3, Wang Mai, Pathum Wan, Bangkok 10330. The project sits in the prime Siam - Pathum Wan area, about 270 meters from BTS National Stadium and around 750 meters from BTS Siam, making it attractive for both residence and long-term investment in one of Bangkok's rare freehold inner-city neighborhoods.

The project comprises 1 building with 7 floors and only 28 residential units, offering a high level of privacy. Parking is provided at approximately 100 percent of total units. Unit types include 1-bedroom, 2-bedroom, 3-bedroom, and penthouse layouts, with usable areas starting from around 50 - 157 square meters. The design focuses on calm, private living within a quiet residential lane in the city center.

Facilities include a saltwater swimming pool, fitness room, garden, lobby, lounge, and premium common areas. Security features include 24-hour security guards, CCTV, and key card access control.

The project was completed around 2021. It was developed by Pruksa Real Estate Public Company Limited and managed under a luxury residential standard. Nearby landmarks include Siam Center, Siam Discovery, MBK Center, Chulalongkorn University, and leading hospitals. Its key strengths are limited units, strong privacy, and a central location with consistent demand from end-users and upscale tenants.

The Reserve Kasemsan 3 (Kasemsan 3 Alley, Pathum Wan) is a prime CBD condominium supported by steady demand from office workers and families tied to nearby schools. Connectivity is a key driver: it is about 550 m from BTS National Stadium, making Siam and Ratchathewi easily reachable.

• 2026 resale pricing: a typical 1-bedroom 38 sq.m. trades around THB 9.5M, or roughly THB 250,000 per sq.m.
• Observed market band: THB 230,000-280,000 per sq.m., depending on floor, view, and unit condition.
• Average rent in 2026: about THB 35,000 per month for a 1-bedroom.

Rental Yield (simple): annual rent THB 35,000 x 12 = THB 420,000. Divide by purchase price THB 9,500,000 = 4.42% per year (before common fees, taxes, and vacancy).

Capital gain outlook: using an estimated 2024 midpoint near THB 235,000 per sq.m. and a 2026 level of THB 250,000 per sq.m., the implied growth is about 6.4% over two years, or roughly 3.2% per year. Upside is supported by limited new supply close to Siam and the scarcity of quiet inner-city alleys. However, investors should factor in tenant competition from nearby high-end projects such as Villa Rachatewi and The Address Chidlom, which can cap rent growth if the market softens.
