State Sukhumvit 42: Thonglor-Adjacent Mid-Range Condo Reviewed

If you have been hunting for a condo that sits close to Thonglor without the Thonglor price tag, State Sukhumvit 42 probably landed on your shortlist. This mid-rise project by Syntec sits on Sukhumvit Soi 42, which places it just across from the mouth of Thonglor on the even-numbered side of Sukhumvit Road. It is the kind of building that quietly appeals to young professionals and couples who want to be near the action but refuse to blow their entire salary on rent. I have walked through the building multiple times and talked to tenants who live there. Here is an honest breakdown of what you are actually getting.

Location: Almost Thonglor, Technically Ekkamai

State Sukhumvit 42 sits about 700 meters from BTS Ekkamai station. That is roughly a 10 minute walk, or a quick 25 baht motorcycle taxi ride from the main road. Soi 42 itself is a quieter residential street, which means you dodge the noise and foot traffic that define the main Thonglor strip on Soi 55.

But here is the real perk. Walk out the front, cross Sukhumvit, and you are basically at the entrance to Thonglor. The restaurants, cafes, and nightlife of Thonglor Soi 13 through Soi 17 are all within a short ride. Gateway Ekkamai mall is roughly five minutes away on foot, and the Eastern Bus Terminal sits right at the BTS station if you ever need a weekend trip to Pattaya or Ban Phe.

Picture this: you finish work at a Thonglor co-working space, grab dinner at a Japanese spot on Soi 55, then hop a motorcycle back to your quiet soi for under 30 baht. That is the daily rhythm of living here. You borrow Thonglor's lifestyle without paying Thonglor's rent.

Unit Sizes and Layout Quality

State Sukhumvit 42 offers mostly one-bedroom units at around 28 to 31 square meters. There are a few studio layouts closer to 24 square meters and some larger one-bedroom units that stretch to about 35. The building completed in 2019, so finishes still look relatively fresh compared to older stock in the area.

The developer used a fairly efficient layout. Kitchens are compact but functional, with a two-burner electric hob and enough counter space to prep a basic meal. Bathrooms come with rain showers, and most units face either the city or a low-rise residential pocket, which means decent natural light.

One thing I noticed is that the 28 square meter units can feel snug if you own a lot of stuff. A friend who moved in with two large suitcases and a guitar found that storage ran out fast. If you are someone who accumulates things, aim for the 31 or 35 square meter options. The price jump is usually only 2,000 to 3,000 baht per month, and the extra space makes a real difference in daily comfort.

Rent Prices and Value for Money

As of mid 2025, studios here typically list between 10,000 and 13,000 baht per month. Standard one-bedroom units go for 13,000 to 17,000 baht, and the larger one-bedrooms can hit 18,000 to 20,000 depending on floor, furnishing, and how motivated the landlord is.

For context, a comparable one-bedroom in a Thonglor building like Noble Remix or HQ Thonglor would run you 18,000 to 28,000 baht. You are saving anywhere from 5,000 to 10,000 baht monthly by choosing State Sukhumvit 42 and only adding a few minutes to your commute. Over a 12 month lease, that saving could cover a round trip flight home or a solid vacation budget.

Common charges run around 45 to 55 baht per square meter, which is standard for this class of building. Electricity is usually billed at the government rate if you sign a contract directly with the Metropolitan Electricity Authority, though some landlords mark it up to 7 or 8 baht per unit. Always ask before signing.

Facilities and Day to Day Living

The rooftop is the highlight here. There is a decent swimming pool with a city view, a small gym with cardio machines and free weights, and a rooftop garden area. The gym is not massive, so serious lifters will probably still want a Fitness First or Jetts membership nearby. But for casual workouts, it does the job.

The lobby uses keycard access, and there is 24 hour security on site. Parking exists but is limited. If you own a car, confirm a spot before signing your lease. Most residents here rely on BTS, motorcycles, or ride-hailing apps anyway.

For groceries, you have a Tops Daily at Gateway Ekkamai and several smaller convenience stores along Sukhumvit. A tenant I spoke with mentioned that food delivery apps work well at this address because riders can access the building easily from the main soi. That sounds minor, but anyone who has lived in a gated compound with complicated delivery access knows it matters.

Who Should Consider This Building

State Sukhumvit 42 fits a specific profile. You are a young professional or a couple earning a combined income of 50,000 to 80,000 baht per month. You want to live near Thonglor but you also want to save money. You do not need a massive gym or a luxury lobby. You care more about location efficiency and keeping your rent reasonable.

It is less ideal for families with children because the units top out at one bedroom and the building lacks a playground or kids' area. It also may not suit people who work on the Silom or Sathorn side of town, since the commute via BTS from Ekkamai to Chong Nonsi takes about 30 minutes during rush hour.

Think of someone like a digital marketer working remotely from Thonglor cafes who wants a clean, modern base without the premium. That is the sweet spot for this building.
