The Icon III Thonglor

The Icon III Thonglor is a low-rise condominium located at 858 Khlong Tan Nuea, Watthana, Bangkok 10110, in Thonglor Soi 55. The project is situated in one of Bangkok's well-known residential neighborhoods, surrounded by upscale dining venues, lifestyle destinations, and premium housing. Completed in 2006, the development was created by Triviwat Co., Ltd. and is designed to offer a relatively private living environment with a limited number of units.

The project consists of 1 building, 9 floors, and approximately 161 residential units, with on-site parking available for residents. Unit types include 1-bedroom, 2-bedroom, 3-bedroom, and penthouse layouts. Room sizes are generally spacious, making the project suitable for owner-occupiers as well as investors targeting expatriate tenants in the Thonglor area.

Facilities include a swimming pool, fitness center, garden, passenger elevators, and common areas for daily use. Security features include 24-hour security guards, CCTV, and key card access. In terms of transportation, the project is about 2.6 kilometers from BTS Thong Lo Station and around 2.8 kilometers from BTS Ekkamai Station. The location is especially suitable for residents who travel by car, with convenient access to Sukhumvit Road, Phetchaburi Road, and Ekkamai. The property is managed under a condominium juristic person responsible for maintaining the building and common areas.

The Icon III Thonglor in 2026 remains a Thonglor resale condo with steady-to-slightly-rising pricing, supported by rental demand from expats and professionals along Sukhumvit. The project sits about 1.3 km from BTS Thong Lo, which helps maintain leasing velocity. Buyers, however, tend to negotiate more compared with newer launches, while nearby resale options such as Ivy Thonglor provide direct comparables.

• Resale price per unit (1-bed, 50 sq.m.): around THB 7.4 - 8.2 million
• Average selling price per sq.m.: about THB 148,000 - 165,000 per sq.m.
• Average rent: THB 30,000 - 35,000 per month (roughly THB 600 - 700 per sq.m. per month)

Rental yield quick math: buy at THB 7.8M and rent at THB 33,000 per month. Annual rent = 33,000 x 12 = THB 396,000. Gross yield = 396,000 ÷ 7,800,000 = 5.08% per year (before common fees, vacancy, and taxes).

Capital gain view: using a typical Thonglor resale growth range of 2 - 4% per year, a THB 7.8M unit may reprice to about THB 8.0 - 8.1M within 12 months, implying THB 160,000 - 310,000 in potential price appreciation. Units with renovated interiors, open views, and mid-to-high floors usually outperform the average in both liquidity and achievable pricing.
