St Paul's Girls' School Brand Brings Its First Bangkok Campus to Rama III
The co-educational school, embedded in a THB 14.4 billion mixed-use development, opens in September with around 300 students, adding a storied London name to the city's British school wave.
Bangkok's incoming cohort of British-branded schools has a notable addition. SPGS International School Bangkok, carrying the ethos of St Paul's Girls' School, will open to nursery and primary students in September 2026, anchoring a THB 14.4 billion (roughly USD 445 million) mixed-use development by Country Group Development PCL on Rama III Road, according to Kaohoon International.
The school will be co-educational from the outset, a deliberate departure from the single-sex model at its London parent, which has been all-girls since 1904. Founding Headmaster Leigh O'Hara, who spent eleven years as a senior leader at the London campus, will oversee a British curriculum enriched with Thai language and cultural elements, with an IB Diploma pathway planned for sixth-form students.
What the campus offers
The 9.1-acre site includes a 600-seat auditorium, two swimming pools, a professional recording studio, a black box theatre, a skyline football pitch, and a dedicated forest school for outdoor learning. An Innovation Centre and specialist wellbeing facilities complete the offering. Around 300 students are expected in the first cohort, all from nursery through Year 6. Years 7 to 9 will be added in 2027, with the full school eventually reaching around 1,700 students.
The Rama III location, south of the Sathorn business district, has attracted several new high-end residential projects in recent years and is increasingly seen by developers as an emerging corridor for expatriate families. Country Group Development, listed on the Stock Exchange of Thailand, has positioned the school as an anchor tenant of a broader estate it describes as premium residential.
Joining a crowded September
SPGS Bangkok arrives in the same academic year as Dulwich College Bangkok, Highgate International School Thailand, and Wycombe Abbey International School Bangkok, all of which open in August. The near-simultaneous arrival of four premium British-curriculum schools marks the most concentrated wave in Thailand's modern international school history. The country's total international school count has risen from roughly 100 in 2014 to nearly 280 today, driven largely by demand from Bangkok's growing professional expatriate population and locally educated upper-middle-class families seeking overseas university pathways.
For families considering the school, the September start date, slightly later than the August norm, gives an extra few weeks before term. Admissions for 2026 to 2027 remain open, with the school targeting a small initial intake to allow time to embed its culture before scaling.
