[4] Administratively operating as an Australian company limited by guarantee since 17 March 1997, Meriden was founded by Jane (Jeannie) Monckton in 1897, at Agnes Street, Strathfield.

Monckton had decided to home school her two sons due to a lack of suitable educational facilities for boys in the Strathfield area.

Friends and neighbours clamoured to have their children join the two boys under her instruction, and so it was decided to establish Meriden, a school with approximately 19 students and two staff to assist.

Turner continued at Woodward Ave until larger premises could be found near Santa Sabina College on the Boulevarde, moving again soon after to its current location in the original Redmire Estate, on Redmyre Road.

[5][6] In 1918, following the 1916 changes to Department of Education requirements, Turner approached the Sydney Church of England Girls' Grammar School (SCEGGS) in Darlinghurst with the concept of amalgamation.

Further negotiations were however prevented due to financial commitments, and the SCEGGS Council suggested that a group of local church people might be interested.

[5] As Turner's health deteriorated, there was a suspicion that the school might close, and subsequently, a group of local people met to discuss the future of Meriden.

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 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.

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.
