Watermark Chaophraya River

Watermark Chaophraya River is located at 1559 Bang Lamphu Lang, Khlong San, Bangkok 10600. This is a high-rise riverside condominium developed by Major Development Public Company Limited and completed around 2012. The project consists of 2 residential towers, 28 and 52 storeys high, with approximately 486 units in total and parking for around 80% of the units.

Unit types include 2-bedroom, 3-bedroom, 4-bedroom residences and penthouses, with relatively large living areas suitable for families and buyers seeking an upscale residence by the Chao Phraya River. One of the project’s key strengths is its panoramic river view and spacious common area, offering a more private residential atmosphere.

Facilities include a riverside swimming pool, fitness center, tennis court, sauna, landscaped gardens, children’s playground, multi-purpose room, private pier, and resident lounge areas. Security features include 24-hour security guards, CCTV, key card access, and controlled building entry systems.

The project is about 2.3 kilometers from BTS Krung Thon Buri Station and is also close to ICONSIAM, Sena Fest, Taksin Hospital, and the Sathorn business district. This location is suitable for both long-term living and investment in the Chao Phraya riverside zone. The property is managed by the condominium juristic person management team.

Watermark Chaophraya River in Khlong San is a riverfront condominium where 2026 resale pricing remains relatively resilient versus other Thonburi areas. Nearby BTS-oriented projects such as Nye by Sansiri and Hive Taksin help support rental demand from office workers commuting to Sathorn-Silom, making this asset more “hold for rent” than short-term flipping.

• Resale price per unit: 1-bedroom 52 sq.m. around THB 6.5 million
• Price per sq.m.: about THB 125,000 per sq.m. (6,500,000 - 52)
• Average rent: about THB 25,000 per month for a comparable unit

Rental Yield (simple calculation): annual rent = 25,000 x 12 = THB 300,000. Yield = 300,000 - 6,500,000 = ~4.6% per year (excluding common fees, taxes, and vacancy). This level is considered competitive for a river-view condo in the secondary market.

Capital Gain outlook: using a conservative 2-3% annual growth assumption from THB 6.5 million, a reasonable 12-month value range is THB 6.63-6.70 million. Key risks are resale supply and building condition, which can impact achievable selling prices more than in newer BTS-adjacent developments.
