Open since 2021, Cube School Saint-Germain-en-Laye currently welcomes over 50 children of 21 different nationalities in a resolutely international environment.
The school is designed for English-speaking and expatriate families moving to France, as well as French families seeking genuine English immersion for their children.
Located in fully renovated former stables, the school enjoys an exceptional setting with three beautiful, spacious rooms designed by an architect, and a garden including a dedicated vegetable patch.
Led by Sinéad Heslin, Cube School Saint-Germain-en-Laye offers daily bilingual immersion, supported by native English-speaking educators, allowing children to learn French progressively while maintaining a high level of English.
This approach fosters a smooth integration into the French school system and effectively prepares children to enter Year 1 (CP) in the region’s international schools.
A true springboard, Cube School Saint-Germain-en-Laye offers personalized support, enriched by sports and music activities, within a secure and caring environment designed to give children confidence, stability, and an openness to the world.
Cube School Saint-Germain-en-Laye is a member of the Association Montessori de France.
