Siamese Exclusive Sukhumvit 31: Boutique Phrom Phong Condo Reviewed

If you have been hunting for a condo near Phrom Phong that does not feel like a giant anonymous tower, Siamese Exclusive Sukhumvit 31 probably landed on your shortlist already. This low-rise project sits on one of the most walkable sois in lower Sukhumvit, close enough to the BTS to be convenient but tucked far enough off the main road to actually feel peaceful. I have walked through the building multiple times and talked to tenants who live there. Here is an honest breakdown of what you are getting, what you are giving up, and whether the rent makes sense in today's market.

Location and Getting Around from Sukhumvit 31

Siamese Exclusive Sukhumvit 31 sits on Sukhumvit Soi 31, roughly a 7 to 9 minute walk from BTS Phrom Phong. That walk is mostly flat and shaded, passing a string of Japanese restaurants, coffee shops, and the entrance to Soi 31's quieter residential stretch. If you work anywhere along the Sukhumvit BTS line, say Asoke or Chong Nonsi, your door to desk commute is totally manageable.

Soi 31 itself connects through to Sukhumvit Soi 39, which means you can also cut over to BTS Phrom Phong via the Emquartier side or loop through to Thonglor without hitting Sukhumvit Road at all. Motorcycle taxis line up at the mouth of the soi, and a Grab from here to Asoke intersection rarely costs more than 50 to 70 baht.

For a real scenario, imagine you work at one of the offices in Exchange Tower at Asoke. You walk out of Siamese Exclusive, grab a motorcycle taxi to BTS Phrom Phong for 15 baht, ride one stop, and you are at your desk in under 20 minutes total. That is a commute most people would kill for in this city.

Building Design and Unit Layout

This is an 8 story building with around 160 units, making it genuinely boutique by Bangkok standards. The developer, Siamese Asset, positioned it as a mid to upper tier project with a design that leans modern and clean. Lobbies and hallways are well maintained, and the building does not have that "500 units fighting for two elevators" problem that plagues so many large towers nearby.

Units come in one bedroom and two bedroom configurations. The one bedrooms range from about 35 to 45 square meters, while two bedrooms sit around 60 to 80 square meters. Ceiling heights are standard, but the layouts make efficient use of space. Kitchens are typically open plan with a counter bar, and most units come with built in wardrobes and decent bathroom finishes.

One thing I noticed when visiting a 40 square meter one bedroom on the 6th floor: the balcony faces into a relatively open area, so you get natural light without staring directly into another building's living room. That is surprisingly rare in this part of Sukhumvit, where plot density is high and soi setbacks are narrow.

Facilities and Day to Day Living

The rooftop pool is the standout here. It is not Olympic sized, but for a building this size, it feels generous, and the views toward the Sukhumvit skyline are genuinely nice in the evening. There is a small fitness room with cardio machines and free weights. It covers the basics but will not replace a dedicated gym membership if you are serious about training.

Security uses a key card system for lobby and elevator access, and there is 24 hour reception. Parking is limited, which is common for low rise projects on these sois. If you own a car, confirm parking availability before signing a lease because spaces fill up fast.

A friend of mine who rented here for about 18 months mentioned that the building management is responsive. When his AC unit had a drainage issue, maintenance showed up the same afternoon. That kind of responsiveness matters more than fancy marble lobbies when you are living somewhere day to day.

For groceries, Villa Market on Sukhumvit 33 is a short walk, and the massive Emquartier supermarket is about 10 minutes on foot. Bumrungrad International Hospital is also just a few minutes away on Soi 3, which is a major plus for families or anyone who wants top tier medical access nearby.

Rental Prices and Value for Money

As of mid 2025, rental prices at Siamese Exclusive Sukhumvit 31 typically fall between 22,000 and 32,000 THB per month for a one bedroom unit, depending on floor, furnishing quality, and lease terms. Two bedroom units range from about 35,000 to 55,000 THB per month. According to data from DDproperty, the average rent for a one bedroom condo in the Phrom Phong area sits around 25,000 to 35,000 THB per month, which puts Siamese Exclusive right in the competitive middle of the market.

You will typically pay two months security deposit plus one month advance rent to move in. Some landlords here are flexible on furnishing upgrades if you commit to a 12 month lease, so do not be afraid to negotiate for a new mattress or a washing machine if the unit is missing one.

Here is where it gets interesting from a value perspective. You are paying similar rent to what many units in larger projects like Supalai Premier at Asoke or The Lofts Ekkamai command, but you are getting a quieter, lower density living experience. The trade off is fewer resort style amenities and a slightly longer walk to the BTS.

How It Compares to Nearby Condos

Phrom Phong and the surrounding area have no shortage of rental condos. To make your decision easier, here is how Siamese Exclusive Sukhumvit 31 stacks up against a few popular alternatives in the same neighborhood.

Building	Location	1 Bed Size (sqm)	1 Bed Rent (THB/month)	Walk to BTS	Total Units
Siamese Exclusive Sukhumvit 31	Soi 31	35 to 45	22,000 to 32,000	7 to 9 min (Phrom Phong)	~160
The Diplomat 39	Soi 39	40 to 55	30,000 to 45,000	10 min (Phrom Phong)	~320
Noble Remix	Thonglor	40 to 50	20,000 to 30,000	3 min (Thong Lo)	~500
H Sukhumvit 43	Soi 43	30 to 42	18,000 to 28,000	5 min (Phrom Phong)	~220
Quattro by Sansiri	Soi 26	55 to 65	40,000 to 60,000	5 min (Phrom Phong)	~440

Noble Remix offers a lower price point and is practically on top of BTS Thong Lo, but it is a much larger, busier building and the units are starting to show their age. Quattro by Sansiri is a clear step up in luxury and size, but you are paying nearly double the rent. Siamese Exclusive hits a sweet spot for renters who want a modern, quiet building without luxury tower pricing.

Who Should Rent Here and Who Should Not

Siamese Exclusive Sukhumvit 31 is a strong fit for single professionals or couples who work along the BTS Sukhumvit line and value a calm living environment over flashy amenities. If you are someone who comes home after a long day and just wants a clean, well designed space in a quiet building, this checks the boxes.

It is also a solid pick for remote workers. The building is quiet during the day, the wifi infrastructure in the area is strong thanks to fiber coverage from providers like AIS, and you have plenty of cafes on Soi 31 and Soi 33 to work from when you need a change of scenery.

Who might want to look elsewhere? Families with young kids who need more space will probably find the one bedrooms too tight and the two bedrooms only borderline workable. If you need a large pool, a kids play area, or a serious gym, the facilities here are too modest. And if being directly on top of a BTS station is non negotiable for your commute, buildings like Noble Remix or TELA Thonglor will suit you better.

I recently spoke with a couple who moved here from a high rise near Nana. They told me the biggest difference was simply noise. Their old building faced Sukhumvit Road directly, and even on the 20th floor, the traffic drone was constant. At Siamese Exclusive, their 5th floor unit on Soi 31 feels genuinely peaceful, especially at night. For them, that trade off was worth every baht.

Practical Tips Before You Sign a Lease

Always visit the actual unit you plan to rent, not just a show unit or photos. Conditions vary a lot between landlords in any building, and some owners at Siamese Exclusive have renovated beautifully while others have left original furnishings that are starting to look tired after several years.

Check the view from the unit. Some sides of the building face neighboring structures fairly closely, while others open up toward Soi 31's tree line. The difference in natural light and privacy is significant.

Ask about electricity and water billing. Most landlords here charge a markup on electricity, typically 7 to 8 baht per unit instead of the MEA rate of around 4 to 5 baht. Over a full year, that markup adds up, especially if you run the AC heavily during hot season from March through May.

Siamese Exclusive Sukhumvit 31 is one of those buildings that does not scream for attention but quietly delivers a comfortable, well located rental experience in one of Bangkok's most liveable neighborhoods. If the Phrom Phong area fits your lifestyle and budget, it absolutely deserves a spot on your shortlist.
