Rama Mansion Sukhumvit 12

Rama Mansion Sukhumvit 12 is located at 43-47 Sukhumvit 12, Khlong Toei, Bangkok 10110, in a convenient central Sukhumvit location. The project is close to BTS Asok, about 700 meters away, BTS Nana, about 800 meters away, and MRT Sukhumvit, around 750 meters away, making it suitable for both residential living and rental investment in the city center.

This condominium is a Low Rise residential project. Publicly available information about the development is quite limited, and verified details on the number of buildings, floors, units, and parking spaces are not clearly confirmed. Based on resale and rental listings, the project mainly offers spacious 2-bedroom and 3-bedroom units, reflecting the larger layouts commonly found in older Sukhumvit residences and appealing to long-stay residents and families.

Facilities found in market listings include a swimming pool, parking area, and passenger elevator. Basic security features such as building access control and on-site staff are also mentioned. However, the completion year, developer name, and management company could not be consistently verified from public sources, so buyers or tenants should confirm these details directly with the juristic office or ownership documents before making a decision.

The project stands out for its private setting within Sukhumvit 12 while remaining close to Terminal 21, Robinson Sukhumvit, Korean Town, and Benjakitti Park. This makes it an interesting option for those seeking a centrally located Sukhumvit condo with a more residential atmosphere. For a nearby project, see Ivy Thonglor (ไอวี่ ทองหล่อ)

Rama Mansion Sukhumvit 12 sits in early Sukhumvit, supported by office, hotel, and expat demand. From the project’s location in Sukhumvit 12, it is roughly 750 m to BTS Nana and 900 m to BTS Asok, which helps rental liquidity even in a competitive market.

• 2026 resale pricing: typical units trade around THB 4.2-6.8M (studio to 2-bed), averaging THB 120,000-145,000 per sq.m. depending on condition and renovation.
• Average rent: about THB 20,000-38,000 per month for 35-65 sq.m. units, with a commonly achievable midpoint near THB 28,000 per month.
• Rental Yield (worked example): a 45 sq.m. unit priced at THB 5.85M (THB 130,000 per sq.m.) rented at THB 28,000 per month generates THB 336,000 per year. Yield = 336,000 ÷ 5,850,000 = 5.7% p.a. (gross, before costs).

Capital gain outlook: as an older building versus new launches along Sukhumvit and Rama 4, price growth is usually steady rather than sharp. A realistic 2026-2028 expectation is 1-3% per year, with upside skewed to well-maintained, renovated units. Newer projects may compete for tenants, so investors should focus on entry price per sq.m. and “move-in ready” fit-out to protect yield.
