Project Concept
The Bangkok Thanon Sap is shaped by a “quiet within the city” design idea, responding to Si Phraya-Bang Rak where heritage shophouses, long-standing business streets, and contemporary creative spots coexist. The project translates the character of Thanon Sap into a residence that feels rooted in the old-city atmosphere while functioning like a modern urban home.
The architectural language focuses on clean lines, restrained colors, and solid-looking materials to blend with the surrounding commercial and office context. At the same time, it introduces openness through well-placed voids and semi-outdoor pockets, aiming to bring in daylight and ease the sense of density typical of inner Bangkok. Interior planning prioritizes real usability and efficient layouts, supporting both end-users and investors targeting rental demand from nearby working populations.
Shared spaces are arranged as a buffer from CBD intensity, with more private-feeling corners for working, reading, and casual socializing. This approach reflects current urban lifestyles where home must flex between rest and productivity. Overall, the design positions the project as a calm, practical address with a distinct identity in the Bang Rak area.
Project Highlights
The Bangkok Thanon Sap is located in Si Phraya-Bang Rak, a long-established inner-city district where offices, hotels, and riverside lifestyle converge. This address works well for end-users who want a central base and for investors targeting steady rental demand from CBD employees and expatriates around Silom-Sathorn.
- Strategic Bang Rak location close to Silom, Sathorn, and Charoen Krung, surrounded by local eateries, cafes, and art spots, making day-to-day living convenient without long commutes.
- Flexible connectivity with BTS Chong Nonsi about 1.7 km away and BTS Saphan Taksin about 1.8 km away, linking directly to major office clusters and Sathorn Pier for river transport.
- Strong surrounding demand drivers near Lerdsin Hospital and Saint Louis Hospital, plus dense office buildings in the Silom corridor, supporting long-term rental occupancy.
- A calmer micro-location on Thanon Sap, typically quieter than main roads while still offering easy access to ICONSIAM and Samyan for shopping and dining.
Description
The Bangkok Thanon Sub is a high-rise condominium located on Thanon Sub Road, Si Phraya, Bang Rak, Bangkok 10500. Positioned in a central business area, the project offers convenient access to Silom, Sathorn, and Samyan. It was developed by Land and Houses Public Company Limited and completed around 2020.
The project consists of 1 residential building with 31 floors and approximately 402 units. Parking is provided for about 67% of the total units. Unit types include 1-bedroom, 2-bedroom, and penthouse layouts, designed to suit urban living and buyers seeking long-term rental potential in the Bang Rak - Si Phraya area.
Facilities include a lobby, swimming pool, fitness center, lounge, landscaped garden, and multipurpose areas. Security features include 24-hour security personnel, CCTV, key card access, and controlled entry systems. Building management is maintained to a luxury condominium standard.
A key advantage of the project is its location near MRT Sam Yan Station, approximately 650 meters away, and BTS Sala Daeng Station, around 1.4 kilometers away. Nearby landmarks include Samyan Mitrtown, Chamchuri Square, Bangkok Christian Hospital, and the Silom business district. For comparison with another project, see Bangkok Feliz Krungthonburi Station.
Price Trend
The Bangkok Thanon Sap in Si Phraya-Bang Rak remains a CBD-adjacent condo market in 2026, supported by office demand around Silom-Sathon and the Charoen Krung hotel belt. The nearest mass transit access is BTS Chong Nonsi at about 1.6 km, followed by BTS Sala Daeng at about 1.9 km, which helps sustain rental liquidity from white-collar tenants.
- Resale price per unit: 1-bedroom 35 sq.m. averages THB 6.3M
- Average selling price per sq.m.: ~THB 180,000
- Average rent: ~THB 25,000 per month (35 sq.m.)
Rental Yield (simple): annual rent THB 25,000 x 12 = THB 300,000. Yield = 300,000 - 6,300,000 = 4.76% per year (before common fees, vacancy, and taxes). This sits in a competitive range for CBD-focused condos where tenants prioritize location and convenience.
Capital Gain view: using an indicative 2024 level near THB 170,000 per sq.m. rising to THB 180,000 per sq.m. in 2026 implies a gain of ~5.9% (about 2.9% per year on average). Upside is steady rather than explosive, as supply in the wider Silom-Sathon market remains meaningful. The project fits investors seeking balanced income plus moderate appreciation over a medium-to-long holding period.
