Ashton Silom

Ashton Silom is a high-rise condominium located on Silom Road, Suriyawong, Bang Rak, Bangkok 10500, in one of Bangkok’s prime CBD locations. The project offers convenient access to both Silom, Sathorn, and Rama 4 Road, and is close to BTS Chong Nonsi Station at approximately 350 meters and BTS Surasak Station at about 550 meters. This location makes it attractive for both owner-occupiers and investors seeking rental demand in the city center.

The development consists of 1 residential tower with 48 floors and 428 units, with approximately 309 parking spaces, or around 72% of total units. Unit types include 1-bedroom, 2-bedroom, and penthouse layouts, with sizes starting from around 31 - 160 square meters. The design focuses on privacy and panoramic city views, appealing to buyers looking for an upscale condominium in the Silom area.

Facilities include a lobby, saltwater swimming pool, fitness center, steam room, lounge areas, sky garden, viewpoint spaces, and multiple passenger lifts. Security features include 24-hour security personnel, CCTV, key card access, and controlled building entry systems.

Ashton Silom was completed in 2018 and developed by Ananda Development Public Company Limited. The juristic management is operated to luxury condominium standards. The project stands out for its proximity to office buildings, BNH Hospital, Assumption College Bangrak, Silom Complex, and many well-known dining spots. It is well suited for urban professionals and investors looking for long-term rental potential. For comparison with another prime city project, see Noble Ploenchit.

Ashton Silom sits in Bangkok’s Silom-Bang Rak CBD. Transit access supports rental demand: about 550 m to BTS Chong Nonsi and about 700 m to BTS Sala Daeng. In 2026, pricing is expected to be stable to slightly positive, driven by office workers and expatriate tenants. Compared with high-grade condos around Ploenchit-Asoke, Ashton Silom typically competes on rent levels, while its edge is proximity to Silom-Sathorn employment nodes.

• Resale price per unit: 1-bed 34 sq.m. around THB 11.2M
• Price per sq.m.: average ~THB 330,000 (commonly seen range THB 300,000-370,000)
• Average rent: 1-bed 34 sq.m. about THB 45,000 per month

2026 Rental Yield: simplified calculation: 45,000 x 12 = 540,000 THB per year; 540,000 - divided by 11,200,000 = 4.8% p.a. (before common fees, taxes, and vacancy). This is relatively attractive for a prime CBD asset with a high price per sq.m.

Capital Gain outlook: using an estimated 2024-2025 resale base around THB 310,000-320,000 per sq.m., a move to ~THB 330,000 implies roughly 3-6% appreciation over 12-24 months. Upside exists but is likely moderate; unit condition, view, and consistent leasing performance are the key drivers.
