The school was originally located in Regent Square in 1870, although little is known about this era. In 1878 the school moved to Endsleigh Gardens in Eaton Square, and its Headmistress was Miss Buchan-Smith. At this time the school had between 20-30 boarders and a few day girls and boys in the nursery. Although the priorities of education in the later nineteenth differed to the ambitions that exist today, there were some similarities, with Miss Buchan-Smith wanting her girls to be well educated with interests beyond the classroom.
