Project Concept
The Room Sukhumvit 21 is shaped around a “calm yet connected” design idea - a private urban residence in the heart of Asoke. The architecture favors clean lines and a refined, understated look, while interior tones lean warm and hotel-like to create a sense of comfort amid a busy business district.
Planning focuses on privacy and livability. From a clearly zoned lobby to unit positioning that welcomes daylight and city views, the layout aims to reduce direct facing and everyday disturbance between neighbors. The concept of true city comfort is reinforced through practical shared spaces - areas for relaxation and fitness that suit a work-centered lifestyle rather than purely decorative amenities.
Set in Khlong Toei Nuea, Watthana, the project’s design responds to mobility and rental demand. It is within an easy walk of MRT Sukhumvit and BTS Asok, roughly 700-900 meters, supporting daily commuting and a car-light lifestyle. From an investor’s perspective, the overall positioning fits end-users and tenants such as office professionals and expatriates who value a neat, premium feel, privacy, and dependable access to the CBD.
Project Highlights
The Room Sukhumvit 21 stands out for its inner-city Asoke-Sukhumvit location in Khlong Toei Nuea, positioned between major business nodes and everyday lifestyle spots. This makes it practical for end-users and attractive for rentals, especially among office professionals and expats who prioritize commute efficiency and a walkable neighborhood.
- Prime urban setting in Sukhumvit 21 with easy access to Asoke, Phetchaburi, and Rama 9. The surrounding area is packed with offices, eateries, and daily services, supporting stable leasing demand.
- Rail connectivity close to BTS Asok (approx. 1.0 km) and MRT Sukhumvit (approx. 1.0 km), plus Airport Rail Link Makkasan (approx. 1.6 km). Ideal for residents who frequently switch between lines or travel to the airport corridor.
- Expressway access with convenient driving routes to Si Rat Expressway, helping shorten travel time toward Rama 9-Ratchada or central Bangkok.
- Facilities focused on real use such as a swimming pool, fitness room, relaxation areas, and security systems-adding comfort and improving rentability.
- Differentiated value offering a calmer feel than main-road projects while staying within reach of the Asoke hub. This balance often supports long-term value retention compared with nearby projects in Thonglor and Rama 9.
Description
The Room Sukhumvit 21 is a High Rise condominium located on Soi Sukhumvit 21, แขวงคลองเตยเหนือ, เขตวัฒนา, Bangkok 10110, in the prime Asoke area with convenient access to both business and lifestyle destinations. The project was developed by Land and Houses Public Company Limited and completed in 2013.
The development consists of 1 building with 28 floors and approximately 213 residential units. Parking is available for around 85 percent of the total units. Unit types include 1 bedroom, 2 bedroom, and penthouse layouts, with usable space starting at about 53 square meters, suitable for both owner occupation and rental investment in the Asoke area.
Facilities include a swimming pool, fitness center, library, garden, multipurpose room, and passenger lifts. The security system features 24-hour security guards, CCTV, key card access, and controlled building entry.
A major highlight is the location near MRT Sukhumvit, approximately 250 meters away, and BTS Asok, approximately 400 meters away. The project is surrounded by Terminal 21, Interchange 21, international schools, and office buildings, making it especially appealing for urban professionals. Building management is handled through the condominium juristic person for common area maintenance and resident services.

Price Trend
The Room Sukhumvit 21 sits in Asoke (Khlong Toei Nuea, Watthana), a rental-driven CBD pocket supported by office demand and expatriates. Connectivity remains the key driver: about 650 m to BTS Asok and around 750 m to MRT Sukhumvit. In 2026, resale pricing is expected to stay firm versus nearby Thonglor and Rama 9 condos, mainly due to the core-Asoke address and stable tenant pool.
- Resale price per unit (1-bed 38-45 sq.m.): ~THB 7.2-9.2M
- Average resale price per sq.m.: ~THB 190,000-215,000
- Average rent: ~THB 32,000-42,000 per month (1-bed)
Rental Yield (gross) example: buy at THB 8.2M, rent at THB 38,000 per month - annual rent THB 456,000. Gross yield = 456,000 ÷ 8,200,000 = 5.56% p.a. (before common fees, tax, and vacancy).
Capital gain view: for 2026-2028, a conservative assumption is 2-4% p.a., supported by Asoke’s employment density and newer launches pricing above the secondary market. Upside is more visible when entry cost is below ~THB 200,000 per sq.m., especially for high-floor, open-view, move-in-ready units that can be leased quickly.
