Ideo Q Siam-Ratchathewi

Ideo Q Siam-Ratchathewi is located at 509 Phaya Thai Road, Thanon Phaya Thai, Ratchathewi, Bangkok 10400. This is a High Rise condominium in a prime central Bangkok location, about 390 meters from BTS Ratchathewi Station and around 650 meters from BTS Phaya Thai Station, with easy access to Airport Rail Link Phaya Thai. The location supports convenient travel to Siam,อโศก, and Suvarnabhumi Airport, making it suitable for both owner-occupiers and long-term investors.

The project was developed by Ananda Development Public Company Limited and completed in 2015. It comprises 1 residential tower with 36 floors and approximately 348 units. Parking is available for about 148 cars, or around 42%, excluding tandem parking. Unit types include studio, 1-bedroom, and 2-bedroom layouts, with sizes starting from approximately 21.00 - 65.00 sq.m. The room layouts are designed for efficient use of space, fitting urban professionals, students, and buyers seeking rental-friendly property in a high-demand area.

Facilities include a lobby, swimming pool, fitness room, library, garden, and high-floor common areas with city views. Security features include 24-hour security guards, CCTV, key card access, and floor-specific access control for added privacy. Property management follows the standard residential management approach commonly associated with Ananda projects.

A key advantage of the project is its proximity to Siam Paragon, MBK Center, Chulalongkorn University, and Phyathai 1 Hospital. From an investment perspective, the Phaya Thai-Ratchathewi area continues to benefit from strong public transport connectivity and central city demand.

Ideo Q Siam-Ratchathewi remains a core CBD-fringe condominium in 2026, supported by steady rental demand from office workers and students. The project benefits from strong connectivity: BTS Ratchathewi is about 200 m away and BTS Phaya Thai about 650 m, which typically improves leasing velocity and resale liquidity compared with outer-city condos under a stable-rate environment.

• Resale price per unit: 1-bedroom around 34 sq.m averages THB 6.8-7.4M
• Price per sq.m: roughly THB 200,000-220,000, depending on floor, view, and condition
• Average rent: THB 25,000-29,000 per month for a 34 sq.m 1-bedroom

Rental Yield (simple calculation): buy at THB 7.2M and rent at THB 27,000 per month. Annual rent = 27,000 x 12 = THB 324,000. Gross yield = 324,000 - 7,200,000 = 4.5% per year (before fees, tax, and vacancy).

Capital gain view: using an estimated 2024 base of THB 190,000-205,000 per sq.m, the move to THB 200,000-220,000 per sq.m in 2026 implies potential appreciation of about 3-6% per year. Upside is driven by proximity to Siam and multi-line rail access, while downside risk is longer selling time versus brand-new launches nearby. Units with practical layouts and competitive rents tend to outperform in both occupancy and exit price.
