Antares Serviced Offices occupies three floors of RSU Tower on Sukhumvit Soi 31 — one of central Bangkok's most recognised business addresses — and delivers a level of personalised service that sets it apart from larger, anonymous flex-space operators. Across 350 workstations, European-style interiors fill with panoramic Bangkok skyline views and abundant natural light, creating a polished corporate environment without the stiffness. Private offices scale from 2 to 20 persons on lease terms as short as a single day, making Antares equally suited to a visiting executive needing a professional base for the week or an international company planting its first Bangkok flag. What consistently draws praise — from reviews and repeat clients alike — is the multilingual team: reception, IT, admin, and a barista on call. Uniquely, in-house lawyers and certified accountants mean legal, tax, and company-registration support sits one floor away, not one timezone away.
Sukhumvit 31, 10110, Watthana, Thailand
Antares is situated in the prestigious Phrom Phong / Sukhumvit Soi 31 corridor of central Bangkok — one of the city's most sought-after business districts. The immediate surroundings include leading international banks, luxury hotels, and some of Bangkok's major shopping destinations; RSU Tower itself houses cafés on the ground floor for a quick break without leaving the building. A short walk brings you to Phrom Phong BTS Skytrain, while Sukhumvit MRT station is also within easy reach, placing the whole city on a direct line. The area's concentration of international restaurants and business-class amenities makes it a natural landing point for overseas companies entering the Thai market. Paid parking is available in the tower for those arriving by car or motorbike.
Located in RSU Tower, 571 Sukhumvit Road, Sukhumvit Soi 31, Bangkok. The building is a short walk from Phrom Phong BTS Skytrain station and Sukhumvit MRT station. Enter through the RSU Tower lobby — Antares Serviced Offices are listed on the directory board in the lobby. Offices are spread across 3 floors (floors 9 and 10 include the business lounge). Parking is available on a pay-per-use basis. Reception is open Monday to Friday, 9:00 AM – 6:00 PM.

I had an office at Antares in the past, and it was one of the best experiences I had insofar as serviced offices are concerned. Great team with attention to details, service-minded, very hospitable, and great comfortable modern facilities, located perfectly on Sukhumvit 33. Highly recommended.

My team and I booked a day office/meeting room with them. The location and facilities are great, but it's their team that makes the real difference. They were very responsive and went out of their way to make us feel comfortable.

Very modern and elegant looking office space. Just a few minutes walk from sky-train station. Good location, and the building has some nice cafés. The office has a fancy coffee machine, that is served upon request. They also have a microwave oven, refrigerator and a sink. The offices are equipped with comfortable chairs and typical office furniture, as well as fast WiFi. I like the temperature, but some have indicated it's sometimes on the chilly side. My only pet peeve is that people are not allowed to operate the coffee machine themselves. Only staff can. However, I was told the machine is delicate, so perhaps it's better that way.
