Siamese Ratchakru

Siamese Ratchakru is a high-rise condominium located on Phahon Yothin Road, Soi Ari 1, Phaya Thai, Bangkok 10400. The project sits in the Ratchakru area, a well-established residential zone connecting Ari and Sanam Pao. It is approximately 650 meters from BTS Ari Station and about 800 meters from BTS Sanam Pao Station, making it suitable for both urban living and rental investment.

The development consists of 1 residential building with 27 floors and around 427 units in total. Parking is available for approximately 70% of the units. Unit types include 1-bedroom, 2-bedroom, and penthouse layouts, with starting sizes of about 34 square meters, serving working professionals, couples, and investors.

Facilities include a swimming pool, fitness center, garden, sauna, lobby, and passenger elevators. The security system includes 24-hour security guards, CCTV, and key card access. The project was completed around 2013 and developed by Siamese Asset Co., Ltd. Building management is provided under standard condominium management practices.

The surrounding area offers cafes, restaurants, office buildings, Phyathai 2 Hospital, and convenient access to Victory Monument, Phahon Yothin Road, and Vibhavadi Rangsit Road. For a nearby condominium project, see Villa Rachatewi.

Siamese Ratchakru (Phaya Thai) in 2026 shows stable pricing supported by inner-city demand near transit. The project is about 900 m to BTS Ari and around 1.1 km to BTS Sanam Pao, attracting office workers from Ari-Phahonyothin and long-stay tenants.

• Resale price per unit (1-bed 30-35 sq.m.): ~THB 4.2-5.4M
• Average resale price: ~THB 145,000-165,000 per sq.m.
• Average rent: ~THB 18,000-24,000 per month (1-bed, furnished)

• Rental Yield (worked example): Buy THB 4.80M, rent THB 22,000/month, assume 5% vacancy. Net annual rent = 22,000 x 12 x 0.95 = THB 250,800. Yield = 250,800 ÷ 4,800,000 = 5.23% p.a.

Capital gain view: Compared with higher-priced central BTS corridors (benchmarking demand dynamics against nearby prime projects such as The Address Chidlom and Villa Rachatewi), upside is likely moderate rather than aggressive. A conservative 2-4% annual appreciation is plausible if the unit is well-maintained and competitively priced. At a base of THB 150,000/sq.m., a 12-month target range of ~THB 159,000-168,000/sq.m. is achievable, with performance mainly driven by unit condition, rental competition, and overall liquidity in the Ari-Phaya Thai submarket.
