Gatehouse School

From the longer Wikipedia page

Gatehouse School is a co-educational independent school based in Sewardstone Road in Bethnal Green in East London, educating pupils from the ages of three to eleven years. The youngest classes follow a Montessori-style education, but the influence of the national curriculum has brought the older classes more into line with mainstream schools. The school admits children from the full ability range, with an emphasis on the Arts, including visits to museums and theatres, as well as sports and outward bound activities.
