Council should manage the school, and debentures were sold in order to obtain the necessary finance. The original home, Wariora, which was owned by Turner, was not included in this transfer but remained her property. On her death, Wariora was transferred to her brother, who sold it on to the gardener and his wife, who in turn ran it as a boarding house. Wariora was eventually purchased by Meriden and was extended to include the school tuck shop. This building has since been demolished. After Turner's death, Grace Ovary was appointed by the Council as the new Headmistress. In 1927, sports practice was carried out at the cow pastures in the grounds of a ruined mansion named Milroy in Broughton Road, Strathfield. The end of this decade saw a growing and profitable school. In 1936, extensive additions were made to the school with the erection of Wallis Hall, seating 450 people. The new building, designed by Thomas Pollard Sampson, encased the existing residence, The Briars, that had become the centre of the school with a new red brick facade along Redmyre Road. The additions included an octagonal chapel forming an apsidal end to the main building with quatrefoil stained glass windows. A library, dormitories, bathrooms and classrooms were part of the development. This building, with further additions, is still the main wing of the school.

Wilson, chairman of the Public Service Board of NSW until the death of his wife Philippa Marion Wilson in 1900. Selbourne became the home of the Walsord family in the first two decades of the 1900s and became the Earwaker family home in the 1927. According to the Australian Securities and Investment Commission, Meriden School was formally registered on 6 March 1929. In 1942, Meriden temporarily became the home of two schools as the Presbyterian Ladies' College (PLC), from the nearby suburb of Croydon, was occupied by the Royal Australian Air Force for the purpose of establishing a top secret Radar Unit. Meriden offered to accommodate the PLC boarders and the school's singing, domestic science, and physical education classes. In spite of
