Little Treehouse Nursery
Soi Akharaphat, Thonglor 13 · Khlong Tan Nuea, Watthana, Bangkok 10110
A small, green-built nursery in the heart of Thonglor running British EYFS with Reggio Emilia and Montessori threads, an on-site chef cooking entirely plant-based meals from scratch, and a sustainability programme — hydroponic garden, zero single-use plastic, composting — that’s built into daily operations rather than bolted on for marketing.

I’ve walked through a dozen-odd early years schools in this city over the past few years, mostly because parents keep asking the same question in slightly different words: where do I put my two-year-old in Thonglor without ending up in a converted shophouse with a laminate floor and a “British curriculum” sticker on the door. Little Treehouse Nursery, tucked down Soi Akharaphat off Thonglor 13, is the one I keep coming back to — not because it’s the biggest or the flashiest, but because it’s the rare case where the sustainability branding actually matches what’s happening on the ground.
What Little Treehouse actually is
Little Treehouse opened in August 2020, started by two mothers who’d spent years teaching before deciding Bangkok needed a nursery built around outdoor play rather than air-conditioned classrooms with a sandpit bolted on as an afterthought. That origin story shows up a lot in nursery marketing — “started by parents who couldn’t find what they wanted” is basically the genre’s founding myth — but here it’s at least consistent with what you find walking in. Hardwood floors, a hydroponic garden balcony, a herb and vegetable patch the kids actually work in, bamboo and reclaimed wood used in construction rather than just mentioned in a brochure.
The school runs four classes — Nursery, Pre-Kindergarten, Kindergarten 1 and Kindergarten 2 — for children roughly 1 to 5 years old, built on the British EYFS framework with Reggio Emilia and Montessori threads woven through it. None of that combination is unique to Little Treehouse. What’s less common is how far they take the “green nursery” idea past the marketing copy: zero single-use plastic on site, homemade soaps and mosquito repellents made in-house, composting food scraps for the garden, a strict rule that meals are plant-based — with dairy and eggs allowed — and cooked from scratch by an on-site chef rather than catered in from somewhere else.
The food and safety detail most nurseries skip
The food programme is worth dwelling on because it’s the part most competing nurseries treat as an afterthought. Little Treehouse posts an actual weekly sample menu rather than vague language about “balanced meals” — Thai-style noodle soup with vegetables from their own garden on Mondays, spaghetti with lentil meatballs on Tuesdays, a California roll sushi lunch with miso soup on Thursdays. It’s a small detail, but it tells you something: most nurseries this size outsource catering. Little Treehouse didn’t.
Safety is handled with the kind of granularity that either reassures you or feels slightly excessive, depending on how anxious a parent you are. Keypad entry, single point of entry and exit, CCTV restricted to management access, background-checked staff, a strict air quality policy that keeps kids indoors once Bangkok’s AQI crosses 150 — which, depending on the month, is not a rare occurrence in this city. They link directly to a live IQAir reading for the school’s own location rather than a generic Bangkok number, which is a small thing that suggests someone there actually checks it. The school sits close enough to Samitivej Sukhumvit 49 that “fast access to a hospital” isn’t just a line in a brochure.
The free shuttle runs to both Thonglor and Phromphong BTS stations, which matters more than it sounds — this stretch of Sukhumvit has brutal traffic at school-run hours and a five-minute walk can become a twenty-minute crawl in a taxi.
What it costs
Fees run from roughly 198,600 baht a year for three-day Nursery up to 376,000 baht a year for five-day Kindergarten 3, plus a 50,000 baht registration fee and extra charges for lunch or nap-time extension. That’s mid-to-upper range for this part of Bangkok — not the cheapest option in the neighbourhood, and Little Treehouse doesn’t pretend otherwise.
| Year Group | Ages | Schedule | Annual Fee (5-Day, THB) |
|---|---|---|---|
| Nursery | 1–2 yrs | 8:00–12:00 | 264,500 |
| Pre-Kindergarten | 2–3 yrs | 8:00–12:30 | 286,500 |
| Kindergarten 1 | 3–4 yrs | 8:00–13:00 | 308,500 |
| Kindergarten 2 | 4–5 yrs | 8:00–14:00 | 352,600 |
| Kindergarten 3 | 5–6 yrs | 8:00–14:00 | 376,000 |
Registration fee 50,000 THB. 3-day and 4-day options available for Nursery and Pre-Kindergarten at lower rates. Lunch and nap-time extension billed separately, 6,000–10,000 THB per term. Figures from the school’s published 2025–2026 fee schedule.
Where it doesn't fit everyone
None of this means Little Treehouse is the right fit for every family, and it’s worth saying plainly: this is a small school. If you’re looking for a sprawling campus with a swimming pool and children running between buildings, this isn’t that — KiddyKare or Storytime will give you more scale. If your priority is an established, decades-old institutional brand with a long enrolment history behind it, the longevity argument cuts the other way too; Little Treehouse has been open since 2020, not 1994 or 2003. What you’re trading scale and tenure for is a smaller, more closely supervised environment where the sustainability positioning isn’t just a slide in the parent info pack.
Other nurseries worth knowing about in the same corner of Bangkok
None of the following are bad choices — several have been operating in this city for longer than Little Treehouse has existed, and plenty of expat families have had good experiences at each. They just solve a slightly different problem.
Storytime Preschool
Sukhumvit Soi 4, near BTS Nana · Est. ~2000, licensed 2003
Storytime has been running for more than 22 years out of Sukhumvit Soi 4, and that longevity is the whole pitch — licensed by the Ministry of Social Welfare in 2003, with a stated roster of 25-plus nationalities and a free shuttle from Nana BTS. It’s a genuinely international, well-tested option for parents who want an established name and don’t need a nature-based programme. The trade-off: Nana is busier and more transient than Thonglor-Ekkamai, and there’s no sustainability angle here at all.
Best for: families wanting a long-established, internationally diverse preschool near central Sukhumvit.
Annabel's Early Years
Ekkamai Soi 10 (two campuses) · Founded 2002
This is probably the closest comparison point on this list. Annabel’s sits in Ekkamai, runs the same broad curriculum mix — British EYFS with Reggio Emilia influence — across two campuses, and has held a genuine NDNA Platinum accreditation from the UK, a real externally verified quality mark. Twenty-two years in the same neighbourhood means a deep, stable parent community. Where it differs: Annabel’s leans on Forest School elements rather than the deliberate green-building, plant-based, zero-plastic programme Little Treehouse runs day to day.
Best for: families wanting EYFS plus Reggio Emilia from a long-established, externally accredited school in the same neighbourhood.
KiddyKare International Kindergarten
Best for: families prioritising facilities and a long operating history over a nature-based curriculum.
Sukhumvit 26, Klongtoey · Est. 1994
KiddyKare has been operating since 1994, one of the older international kindergartens in the city, and it shows in the facilities — a proper swimming pool, dance studio, sensory room, dedicated tricycle track, more physical space than a small nursery can match. EYFS plus Jolly Phonics is solid and well-tested; this is a school that enrolled its 2,000th child back in 2003. It sits closer to Klongtoey than the leafier Thonglor-Ekkamai pocket, and there’s no equivalent of Little Treehouse’s hydroponic garden or plant-based kitchen.
Kids Kingdom International Kindergarten
Best for: parents wanting a quiet residential location without a heavily branded pedagogical angle.
Sukhumvit 47 · Ages 18 months–6 years
Kids Kingdom occupies a quiet stretch of Sukhumvit 47, which a lot of parents will value on its own — less traffic noise, a calmer drop-off than the busier sois nearby. It runs IPC teacher training and a straightforward mission around being a “building block” for each child’s future. It’s a smaller, steadier operation and honestly one of the harder schools to differentiate online; there isn’t much distinctive about its public identity, and no sustainability programme to speak of.
Precious Learners World
Best for: families near Punnawithi/Bang Chak wanting a garden-based curriculum without the Thonglor commute.
Out toward Punnawithi, Precious Learners World is actually the nursery on this list with the most philosophical overlap with Little Treehouse — a “Garden to Table” curriculum built around gardening, cooking and nature-inspired learning. It’s a small, nature-leaning campus with genuinely warm parent reviews. The catch is location and scale: it’s a fair distance from the Thonglor-Ekkamai corridor, the online presence and review base are much thinner than the bigger names on this list, and it runs an American curriculum framework rather than EYFS.
The First Steps International Preschool
Best for: bilingual French-English families wanting EYFS in a central Sukhumvit location.
First Steps has been on Sukhumvit Soi 31 since 1996, offering both British and French curricula — genuinely useful for bilingual French-speaking families, and not something else on this list provides. The EYFS foundation is solid and the school takes children up to age 7, easing the transition into primary school more gradually. Its location, between Asoke and Phrom Phong, is more central than Thonglor but busier and less green, with no sustainability programme.
Every school on this list does something well. None of them combine small-scale intimacy, a genuinely lived-in sustainability programme, and the Thonglor-Ekkamai location the way Little Treehouse does, and that combination is the actual reason it keeps coming up when parents in this part of the city ask each other where to look first.

Frequently asked questions
What is the best nursery in Bangkok's Thonglor area?
Little Treehouse Nursery, on Soi Akharaphat off Thonglor Soi 13, is widely regarded as the standout early years choice for the Thonglor-Ekkamai corridor. It combines British EYFS, Reggio Emilia and Montessori approaches with a sustainability programme that goes well beyond marketing language — a hydroponic garden, plant-based homemade meals, and zero single-use plastic on site.
Is Little Treehouse Nursery good for sustainability-minded families?
Yes. Little Treehouse was built around a green-school concept from the start, with a hydroponic balcony garden, a herb and vegetable patch children work in directly, composting, homemade organic soaps and repellents, bamboo and reclaimed wood used in construction, and a strict zero single-use plastic policy. The kitchen serves entirely homemade, plant-based meals (with dairy and eggs) prepared on site by an in-house chef.
How much does Little Treehouse Nursery cost compared to other Bangkok nurseries?
Annual fees for 2025–2026 range from roughly 198,600 baht for three-day Nursery up to 376,000 baht for five-day Kindergarten 3, plus a 50,000 baht registration fee. Lunch and optional nap-time extension cost extra. This places it in the mid-to-upper range for the Thonglor-Ekkamai area, broadly comparable to Annabel’s Early Years and KiddyKare.
What curriculum does Little Treehouse Nursery follow?
Little Treehouse follows the British Early Years Foundation Stage (EYFS) curriculum, with the Reggio Emilia approach and Montessori methodology layered in, alongside what the school calls a Green School initiative focused on environmental learning.
Is Little Treehouse Nursery accessible by BTS?
Yes. The school provides a free shuttle service to and from both Thonglor and Phromphong BTS stations, which matters in this part of Sukhumvit given how congested the sois can get during school-run hours.
What ages does Little Treehouse Nursery accept?
Children from roughly 1 to 5 years old, across four classes: Nursery, Pre-Kindergarten, Kindergarten 1 and Kindergarten
How does Little Treehouse Nursery handle Bangkok's air quality and pollution season?
The school fits air purifiers in both indoor classrooms and outdoor play areas, gives each child a personal AQI reader, and enforces a policy of keeping children indoors once the Air Quality Index passes 150. The school links to a live IQAir reading for its own location rather than a generic city-wide figure.
