When families first discover Raintree International School, one of the most common questions they ask is: which campus should we choose? Both the Sathorn and Sukhumvit locations deliver the same British EYFS curriculum, the same Reggio Emilia-inspired teaching philosophy, and the same Raintree community experience. But the two campuses are not identical, and for many families, the right choice is genuinely clear once they know what to look for.
This guide walks through everything that matters: location, neighbourhood feel, facilities, the families who tend to choose each campus, and the practical questions you should ask yourself before booking a tour.
What Both Campuses Share
Before comparing the differences, it helps to understand what is the same. Choosing between Sathorn and Sukhumvit is not a choice between two different schools. It is a choice between two expressions of the same school.
Both campuses offer:
- The British Early Years Foundation Stage (EYFS) curriculum, delivered by qualified, experienced teachers
- A Reggio Emilia-inspired environment, in which the physical space is designed as a third teacher alongside peers and adults
- Purpose-built facilities conceived in partnership with early years specialists and designed by leading Thai architects with a focus on sustainable, nature-connected learning
- Small class sizes with high teacher-to-child ratios
- Children aged 1 to 6, spanning Nursery through to Kindergarten Year 2 (Year 1 is also available at both campuses)
- The same admissions process, the same community events calendar, and the same warmth that Raintree parent testimonials consistently describe
The curriculum, philosophy, and quality of care are consistent across both locations. What differs is the environment those things are delivered in, and where each campus sits within Bangkok.
Raintree Sathorn: The Head Office Campus
Location and Neighbourhood
Raintree Sathorn is the school’s founding campus and head office, located at 126 Nanglinchi Road in the Sathorn district of Bangkok.
Sathorn is one of Bangkok’s most established diplomatic and business districts. It runs south from Silom toward the Chao Phraya River, and it is home to embassies, consulates, international law firms, and the riverside neighbourhoods of Bang Rak and Yannawa. Families living in Sathorn, Silom, Riverside, Rama 3, Narathiwas, or the inner south of Bangkok will typically find this campus significantly more convenient.
The campus sits on Nanglinchi Road, a quieter residential street off the main Sathorn arterial. The immediate environment feels genuinely green and unhurried for a school located within one of Bangkok’s most central districts.
The Facilities at Sathorn
Sathorn is the larger of the two campuses in terms of outdoor space and specialist facility variety. The building was designed by a leading Thai architect specialising in sustainable design, and it curves around clusters of raintree trees on the site to create two inner courtyards with naturally ventilated walkways. Floor-to-ceiling sliding glass doors connect classrooms to covered patios and outdoor spaces, so the boundary between inside and outside is almost seamless.
Specialist facilities at Raintree Sathorn include:
- Library with a glass reading porch, outdoor story theatre boxes, and discovery nooks designed for both structured and self-directed exploration
- Sensory Studio with an immersive circular space featuring an interactive floor projector, a backlit LED dome, and a light studio for creative, multimedia play
- Indoor Gym for active physical development in all weather conditions
- Curated Playground with an elevated walkway, a nest built directly within a raintree, a kaleidoscope, platform swings, and a curving slide
- Tree House integrated into the outdoor landscape
- Climbing Wall for physical challenge and confidence-building
- Sand Play Area featuring a preserved tree trunk section as a centrepiece
- Water Play Station, an interactive waterfall wall with cascading basins for redirection and exploration
- Organic Farm Area for early environmental education
- Exploration Studio for science and discovery-based learning
- Cooking Studio for hands-on food and life skills activities
- Well-being Room for emotional regulation and quiet support
- Green Garden with large trees, forming the natural backdrop to outdoor learning
The Sensory Studio, Tree House, Climbing Wall, and Exploration Studio are among the most distinctive facilities at the Sathorn campus and are not matched at Sukhumvit. For families who place particular value on sensory and immersive learning environments, this is worth noting.
Who Tends to Choose Sathorn
Sathorn is Raintree’s original campus, and its parent community reflects the neighbourhood it sits in: a mix of diplomatic families, finance and legal professionals, long-term Bangkok expatriates, and Thai families who live or work in the south and central parts of the city.
It also tends to attract families who are drawn to the outdoor scale and the variety of its specialist learning spaces. If your child thrives in environments with rich sensory input, imaginative outdoor structures, and natural materials, Sathorn’s physical environment is particularly well-suited to that.
Raintree Sukhumvit: The Sukhumvit Soi 26 Campus
Location and Neighbourhood
Raintree Sukhumvit is located at 54 Soi Athakravi, Sukhumvit Soi 26, Klongtoey, Bangkok 10110.
Sukhumvit Soi 26 sits between the BTS stations of Phrom Phong (Soi 24) and Asok (Soi 21), making it one of the most accessible addresses in Bangkok for families commuting by BTS. Families living in Phrom Phong, Thonglor, Ekkamai, Asok, Nana, or anywhere along the Sukhumvit corridor will find this campus significantly easier to reach, especially during school drop-off in Bangkok’s peak morning traffic.
The Sukhumvit corridor is Bangkok’s most internationally dense neighbourhood. It is home to the largest concentration of international restaurants, supermarkets, international hospitals, and expat-oriented services in the city. For newly relocated families who are still building their Bangkok life, being close to the Sukhumvit infrastructure is a genuine day-to-day convenience.
The campus occupies a green, tree-lined compound on Soi Athakravi, which is a residential side soi that runs off the main Sukhumvit 26. Despite its central location, the school environment feels calm and contained, with the same commitment to nature-connected outdoor spaces that defines the Sathorn campus.
The Facilities at Sukhumvit
Sukhumvit shares the core Raintree facility design philosophy: a sustainable building curving around raintree clusters, naturally ventilated walkways, floor-to-ceiling glass connecting classrooms to outdoor spaces, and a rich variety of indoor and outdoor learning environments.
Specialist facilities at Raintree Sukhumvit include:
- Library for reading, exploration, and quiet discovery
- Swimming Pool for water confidence and physical development from an early age
- Indoor Gym for year-round active play and movement
- Curated Playground with climbing, exploration, and imaginative play structures
- Sand Play Area for sensory and creative outdoor play
- Water Play Station for hands-on water exploration
- Organic Farm Area for environmental and life skills learning
- Tree House integrated into the campus landscape
- Community Lounge for family connection and school community events
- Cooking Studio for food education and practical life skills
- Well-being Room for emotional support and regulation
- Green Garden with large trees, forming the outdoor learning backdrop
The most distinctive feature of the Sukhumvit campus is the swimming pool, which is not available at Sathorn. For families who want their young child to develop water confidence and basic swimming ability from nursery age onwards, this is a significant practical advantage.
The Community Lounge is also notable. It signals a deliberate investment in the parent community dimension of school life, providing a welcoming space for coffee mornings, parent workshops, and the informal connections that turn a school community into something more like a village.
Who Tends to Choose Sukhumvit
Sukhumvit attracts a highly international parent mix that reflects the diversity of the surrounding neighbourhood. Testimonials from the campus include families from Korea, Singapore, India, and across Southeast Asia, alongside Thai families who live or work along the Sukhumvit corridor.
Newly relocated families are particularly well-served by the Sukhumvit campus. The BTS accessibility means that even parents who do not yet know Bangkok well can navigate drop-off and pick-up without getting stuck in the inner-city traffic that affects the Sathorn area on school mornings. The proximity to international amenities along Sukhumvit also reduces the learning curve of settling into Bangkok life.
Families who prioritise swimming as part of early childhood development, or who want the social infrastructure of a community lounge built into their school experience, tend to gravitate toward Sukhumvit.

The Questions That Will Help You Decide
If you are still unsure which campus makes more sense for your family, work through these five questions.
1. Where do you live and where do you work? This is the most important factor for most families. A 10-minute drop-off in calm morning traffic is worth more than any facility difference. Map both campuses against your home and your workplace before anything else.
2. Is swimming a priority for your child at this age? If developing water confidence from nursery age is something your family values, Sukhumvit’s pool makes that part of the regular school day rather than an extra-curricular add-on elsewhere.
3. Does your child respond strongly to sensory and immersive environments? The Sensory Studio at Sathorn is one of the most distinctive early years facilities in Bangkok. If your child is a sensory learner who responds well to light, projection, sound, and multi-modal play, it is worth seeing this space in person before deciding.
4. Are you newly relocated to Bangkok? If you are still finding your feet in the city, Sukhumvit’s BTS access and the surrounding international infrastructure can genuinely reduce daily stress during the settling-in period.
5. How important is parent community infrastructure to you? Both campuses run community events and maintain strong parent relationships. But Sukhumvit’s dedicated Community Lounge signals a particular investment in the physical space for that community to gather informally.
Can You Visit Both Before Deciding?
Yes, and Raintree actively encourages prospective families to visit both campuses before making a choice.
A campus visit takes about an hour and gives you a far more accurate picture of each environment than any written comparison can. You will walk the classrooms, meet the teaching team, and see how the outdoor spaces are used during a normal school day. Most families find that one campus feels instinctively right within the first ten minutes of a visit.

If you are not sure which to visit first, book the campus closer to your home. The commute experience, even just one journey for a school tour, will tell you something useful.
A Note on Place Availability
Both campuses are popular, and specific year groups do fill up. If you have a strong preference for one campus, it is worth contacting the admissions team as soon as you are seriously considering Raintree, rather than waiting until you have made a final decision.
If your preferred campus does not currently have a place in your child’s year group, the admissions team will advise you on realistic timelines and whether the other campus might be a practical alternative in the interim.
