The Line Ratchathewi

The Line Ratchathewi is located on Phetchaburi Road, Thanon Phetchaburi, Ratchathewi, Bangkok 10400. It is a high-rise condominium in a central city location, developed by Sansiri Public Company Limited in partnership with BTS Group. The project was completed in 2017 and consists of 1 building with 38 floors, approximately 231 residential units, and parking for around 70% of total units.

Unit types include 1-bedroom, 2-bedroom, and penthouse layouts, with sizes starting from about 27.75 - 79 square meters. The design focuses on privacy and efficient space usage, making it suitable for both owner-occupiers and investors. The project is about 220 meters from BTS Ratchathewi Station and around 650 meters from Airport Rail Link Phaya Thai Station, offering convenient access to Siam, Pratunam, and Asok.

Facilities include a lobby, saltwater swimming pool, fitness room, garden, sky common area, laundry room, and multiple passenger lifts. Security features include 24-hour security guards, CCTV, key card access, and floor-specific access control.

Property management is handled under Sansiri Property Management standards. A key strength of the project is its location in the Ratchathewi area, where rental demand remains strong from office workers, students, and expatriates. Nearby landmarks include Siam Paragon, Platinum Fashion Mall, Chulalongkorn University, and Phyathai 1 Hospital, making it a solid option for both living and long-term investment.

The Line Ratchathewi on Phetchaburi Road is positioned in a core CBD-fringe pocket, about 450 m to BTS Ratchathewi and around 900 m to BTS Phaya Thai. In 2026, resale pricing remains relatively resilient thanks to steady demand from professionals working around Siam-Phaya Thai, with rental liquidity typically stronger than outer-city condos.

• Resale price per unit (1-bed 33-35 sq.m.): ~THB 6.2-7.2M
• Average resale price per sq.m.: ~THB 190,000-215,000
• Average rent (1-bed 33-35 sq.m.): ~THB 24,000-30,000 per month

Rental Yield (2026) quick math: buy at THB 6.6M and rent at THB 27,000 per month. Annual rent = 27,000 x 12 = THB 324,000. Gross yield = 324,000 ÷ 6,600,000 = 4.9% p.a. (before common fees, tax, and vacancy).

Capital Gain view: using a 2024-2025 market band of roughly THB 180,000-200,000 per sq.m. and a 2026 band of THB 190,000-215,000 per sq.m., the implied appreciation potential averages about 2-4% per year. Upside is supported by proximity to Siam and price anchoring from nearby premium projects such as Villa Rachatewi and The Address Chidlom, while downside risk is mainly from high competing supply and rent sensitivity in slower economic cycles.
