Overview
The Base Phetchaburi-Thonglor is a sleek high-rise designed for the "Active Urbanite." Completed in 2022 by Sansiri, the 36-storey tower stands on a high-potential 2-rai plot on New Petchburi Road. The project is defined by its "Yours to Discover" concept, blending bold, modern industrial aesthetics with a high-functioning lifestyle suite.
The project is famous for its standalone 2-storey Clubhouse, which physically separates the co-working and social zones from the main residential tower to enhance privacy. In 2026, it remains a premier asset for professionals working in the nearby Petchburi-Asoke office corridor, valued for its 2.6m ceiling heights, smart home integration (Nasket), and its rooftop wellness facilities that offer a quiet escape from the busy Petchburi thoroughfare.
Developer
Sansiri Public Company Limited is one of Thailand's most prominent developers, and "The Base" represents their dynamic urban brand. The Phetchaburi-Thonglor iteration features higher-end finishes than typical Base projects, aiming at affluent young professionals. The building is professionally managed by Plus Property, with a common area fee (CAM) of ฿59 - ฿63 per sqm and a sinking fund of ฿500 per sqm.
Location & Transit
| Station | Line | Distance | Mode |
|---|---|---|---|
| Thong Lo Area | Road | 400m | Walk (5 min) |
| MRT Phetchaburi | Blue | 2.0km | Shuttle (6 min) |
| Bangkok Hospital | Medical | 700m | Walk (9 min) |
Commute Logistics:
- The Thonglor Bridge: While the address is Phetchaburi Road, residents are only 400 meters from the start of Thonglor (Sukhumvit 55), providing easy access to the district's elite dining scene without the Thonglor price tag.
- Shuttle Connection: To bridge the gap to mass transit, the building operates a frequent shuttle service to the MRT and Airport Rail Link, facilitating a 10-minute commute to the CBD or airport connection.
- Hospital Row: Its location is exceptionally strategic for medical staff and those seeking healthcare, being within walking distance of Bangkok Hospital and a short drive from Piyavate and Rama 9 Hospital.

Facilities
The Clubhouse (Floors 1-2): A separate building housing the Lobby Lounge, a Co-working Hub, and a stylish Outdoor Café. This separate structure prevents external noise and visitor traffic from entering the residential lift lobby.
Wellness Deck (Floor 6): Features a Half-Olympic Saltwater Pool with a "Sunken Seat" area and a high-spec Fitness Center featuring modern LED lighting to energize workouts.
Sky Entertainment (Floor 36): The top floor is a social hub containing the Sky Lounge, a Mini Theater, and a Game Room. This is topped by a Roof Terrace with an Organic Garden where residents can harvest fresh produce.
Pros
- Clubhouse Privacy — Residential tower is separated from social/work traffic.
- Proximity to Thonglor — Close enough to enjoy the lifestyle, but at a lower price point.
- Modern Tech — Nasket smart home system and LIV-24 security.
- Excellent Views — Unblocked skyline vistas toward Thonglor and Ekkamai.
Cons
- Distance to BTS/MRT — Not walkable (2km+); relies heavily on the shuttle.
- No Pets — Strictly prohibited, despite the green rooftop garden.
- Road Noise — Being on the main New Petchburi Road, lower floors may hear traffic.
The Bottom Line
In 2026, The Base Phetchaburi-Thonglor is the "Smart Professional's Gateway." It is the perfect choice for young executives and medical professionals who want a high-spec Sansiri home with elite social facilities at a more accessible entry price than Thonglor proper. If you prioritize building amenities and a "smart" living experience over being directly on the BTS line, this is one of the most stable and modern investments in Huai Khwang.
