Grandville House 1

Grandville House 1 is located at 36 Khlong Tan, Khlong Toei, Bangkok 10110. This condominium is considered a Low Rise residential project in the Sukhumvit inner-city area, close to Thong Lo and Ekkamai, two well-known residential and lifestyle neighborhoods popular among urban professionals and expatriates. The project offers convenient access to Sukhumvit Road and Phetchaburi Road. The nearest mass transit station is BTS Thong Lo, approximately 1.8 kilometers away.

Available public sources indicate that the project was completed in 1981 and developed by Grandville House. The building appears to be around 8 storeys high. However, key details such as the exact number of buildings, total units, parking spaces, unit types, facilities, security system, and juristic management are not clearly verified in publicly available sources. Buyers and investors should confirm these details directly with the building management, juristic office, or current sellers before making a decision.

In terms of livability, Grandville House 1 suits those looking for a low-rise condominium in a relatively private residential setting within the Sukhumvit area. It also provides practical access to Thong Lo, Ekkamai, and Phrom Phong. While complete facility and security information is not publicly confirmed, projects of this type in this location typically provide basic common area services for residents.

A nearby condominium project of interest is Ivy Thonglor.

Grandville House 1 in Khlong Tan-Khlong Toei is an inner-city condo market supported by rental demand from Sukhumvit-Thonglor office workers and expatriates seeking lifestyle convenience. In 2026, pricing is more “stable with gradual upside” rather than a sharp jump, as nearby supply from newer Sukhumvit and Rama 4 developments remains competitive.

• Resale price per unit (2026): typical 1-bedroom, 45 sq.m. averages THB 6.3 million
• Price per sq.m.: about THB 140,000 per sq.m. (6.3m ÷ 45)
• Average rent: 45 sq.m. unit averages THB 28,000 per month
• Rental Yield (quick math): (28,000 x 12) ÷ 6,300,000 = 5.33% per year (before common fees, taxes, and vacancy)

Capital gain view: Comparing with nearby Sukhumvit benchmarks such as Ivy Thonglor and Siri at Sukhumvit, prices are typically supported by location but capped by new-launch competition. A realistic expectation is 2-4% annual appreciation over 2026-2028, equal to roughly +THB 120,000 to +250,000 per unit per year on a THB 6.3m base. Key drivers are unit condition, renovation quality, and consistent tenantability.
