Under the early headmistresses Marian Belcher, Kathleen Collier, Emmeline Mary Tanner and Katharine Westaway the school expanded.

The Junior School acquired a new wing in 1896, and remained there until moving into a building in Adelaide Square in 1985.

It also obtained a pipe organ built by Norman and Beard of Norwich which was used for daily assemblies.

Before its closure, the school had 22 acres (89,000 m²) of games field and a spa centre ('the Canary Cage'), formally opened in 2005 by past pupil Stephanie Cook OBE, (Olympic gold champion and World Champion in the modern pentathlon).

Today there are still those who remember the dreaded Joyce Harding, his daughter, who trained the choirs, and auditioned all junior girls at the beginning of each year.

A governor was heard to remark afterwards how clever the choir were to learn it in such a short time, and in a foreign language.

Before closure about ten per cent of the girls attending the school were boarders, living in four boarding houses: Wimborne Grange, The Quantocks, Westlands and The Chilterns.

In the sports department girls competed at county and national levels, and the hockey and lacrosse teams travelled to the Netherlands, Canada, Australia, and Prague.
