Grand Langsuan

Grand Langsuan is a high-rise condominium located on Soi Langsuan, Lumphini, Pathum Wan, Bangkok 10330. Positioned in one of Bangkok's prime residential areas, the project is close to the Ratchadamri, Chidlom, and Ploenchit districts. It was developed by Grand Asset Hotels and Property Public Company Limited and completed around 1998. The project is regarded as one of the classic luxury condominiums in the Langsuan neighborhood, known for its privacy and large unit sizes.

The development consists of 1 residential building with 36 floors and approximately 104 units. Unit types include 2-bedroom, 3-bedroom, and large penthouse layouts. The residences offer spacious living areas compared with many newer condominiums in the same area, making the project suitable for end-users seeking larger homes in the city center as well as long-term investors. Parking is provided in a relatively high ratio for residents.

Facilities generally include a swimming pool, fitness center, lobby, passenger lifts, and common relaxation areas. Security systems include 24-hour security guards, key card access, and CCTV throughout the property.

In terms of transportation, the project is about 750 meters from BTS Chit Lom Station and around 850 meters from BTS Ratchadamri Station. Nearby landmarks include Lumpini Park, Central Chidlom, Central Embassy, and several leading hospitals. Building management is handled by the condominium juristic person responsible for maintaining the common areas and services. For a nearby project, see Ivy Thonglor.

Grand Langsuan (Lumphini, Pathum Wan) remains a prime CBD condominium in 2026, supported by end-user demand and a steady expatriate tenant base. The location connects well to the Langsuan-Ploenchit lifestyle zone, with BTS Chit Lom about 900 m away and BTS Ratchadamri about 1.1 km.

• Resale price per unit (2026): 1-bedroom, 55 sq.m. averages THB 19.8M
• Average price per sq.m.: ~THB 360,000 (commonly THB 330,000-420,000 depending on floor, view, and condition)
• Average rent: THB 78,000 per month for 55 sq.m. (about THB 1,420 per sq.m. per month)

Rental yield (quick math): (78,000 x 12) / 19,800,000 = 4.73% p.a. before common fees and taxes. This is relatively attractive versus many luxury CBD condos that often trade around 3-4% gross yields.

Capital gain view: using an indicative 2024 average of ~THB 340,000 per sq.m. rising to THB 360,000 per sq.m. in 2026 implies a +5.9% increase, or roughly 2.9% per year. Upside is driven by limited land supply in Langsuan and the area’s “residential-first” character, while the key risk is new luxury supply around Ploenchit-Chidlom competing for the same tenant pool.
