The Room Sukhumvit 21: SC Asset Asok Condo Complete Review

If you've spent any time apartment hunting around Asok, you've probably walked past The Room Sukhumvit 21 without even realizing it. Tucked just off the main Sukhumvit Road on Soi 21, this SC Asset development sits in one of Bangkok's most convenient corridors. It's the kind of building that doesn't scream for attention but quietly delivers a solid living experience. Whether you're a young professional working in the Asok or Phrom Phong area or a couple looking for a well located condo without the mega tower chaos, this one deserves a closer look.

Location and Getting Around from Soi 21

The Room Sukhumvit 21 sits on Asoke Montri Road, which is essentially Soi 21 running north from Sukhumvit. You're roughly a 5 to 7 minute walk to both BTS Asok and MRT Sukhumvit, which gives you access to two of Bangkok's most important transit lines. That dual station access is genuinely useful, not just a marketing line. Need to get to Silom? Take the BTS. Heading to Chatuchak or Lat Phrao? Jump on the MRT.

Your daily life errands are basically handled within a short radius. Terminal 21 is right there for shopping, food courts, and a surprisingly good cinema. Robinson Sukhumvit and Times Square are also within walking distance. For groceries, there's a Tops Market nearby and a Villa Market over on Soi 33 if you prefer imported goods.

Imagine finishing work at an office on Ratchadapisek, hopping on the MRT at Phra Ram 9, and being home in under 15 minutes. That's the kind of commute this location gives you. It also helps that the soi itself isn't as congested as Sukhumvit Soi 19 or the Nana stretch, so getting a Grab or taxi out during rush hour is slightly less painful.

Building Overview and Unit Types

Developed by SC Asset, The Room Sukhumvit 21 is a 24 story residential tower that was completed around 2012. SC Asset is one of Thailand's established developers, and this project reflects their mid to upper range positioning. The building doesn't look flashy from the outside, but the lobby and common areas are kept clean and well maintained, which tells you a lot about the management.

Units come in three main configurations. Studios start around 30 sqm, one bedrooms range from about 42 to 52 sqm, and two bedrooms sit around 65 to 72 sqm. Ceiling heights are decent, and most units have good natural light thanks to full length windows. Kitchens are compact but functional, which is standard for Bangkok condos in this segment.

A friend of mine rented a one bedroom here, around 45 sqm, and found the layout surprisingly livable. The bedroom was separated enough from the living area to feel like a real apartment, not just a glorified hotel room. Bathrooms have proper rain showers, and built in wardrobes come standard in most units.

Facilities and Day to Day Living

The facilities at The Room Sukhumvit 21 are solid without being over the top. There's a rooftop swimming pool with a city view, a well equipped fitness center, a sauna, and a garden area. You won't find a co working space or a golf simulator here, but honestly, most residents just want a clean pool and a gym that actually has the machines they need. This building delivers on that.

Security includes key card access on every floor, CCTV throughout, and 24 hour security staff at the lobby. Parking is available in the basement, though spaces can be tight during peak evening hours. If you're bringing a car, confirm parking availability with the landlord before signing.

One thing residents consistently mention is how quiet the building is. Despite being on a busy soi, the units facing the inner side of the building are remarkably peaceful. If you're sensitive to noise, ask for a unit that doesn't face the main road directly. That small detail can make a huge difference in your quality of life.

Rental Prices and What to Expect

As of 2024 into 2025, rental prices at The Room Sukhumvit 21 generally fall in these ranges. Studios go for about 15,000 to 20,000 THB per month. One bedroom units typically land between 20,000 and 30,000 THB depending on floor level, furnishings, and how recently the unit has been renovated. Two bedrooms range from 30,000 to 42,000 THB.

Compared to newer developments on Sukhumvit like Ashton Asoke or Edge Sukhumvit 23, The Room Sukhumvit 21 offers noticeably lower rents for a similar location. You're trading rooftop infinity pools and Instagram friendly lobbies for a more practical, lived in building that still performs well on the basics.

For example, a couple working in the Asok area could comfortably rent a one bedroom here for around 25,000 THB, walk to work, and still have budget left over for weekend trips. That's a realistic scenario that plays out for many tenants in this building.

Who Is This Condo Best For?

The Room Sukhumvit 21 fits a specific type of renter really well. If you're a working professional, either Thai or expat, who values location and practicality over flashy amenities, this is your kind of building. It's also a good pick for couples who want a proper one or two bedroom layout without paying Thonglor prices.

It's probably not the best fit if you're looking for a brand new luxury experience or if you need extensive family friendly facilities like a kids' play area. Families with young children might find the unit sizes a bit tight and may prefer something along Sukhumvit 39 or 49 where larger units are more common.

The Room Sukhumvit 21 remains one of the more reliable mid range options on the Asok stretch. It won't wow you with flashy branding, but it will give you a comfortable home in a location that makes daily life in Bangkok genuinely easy.
