Established in 1897, Tudor House moved from Sydney to its present rural site in Moss Vale in 1902.

The campus features tree groves and an orchard, dams and creeks, playing ovals, including five cricket ovals, three rugby union fields, and two soccer fields, a 25-metre heated swimming pool, two tennis courts, gymnasium, classrooms for Upper School (Years 4–6) and Lower School (K–Year 3), a boarding house, a school hospital staffed by a registered nurse, and specialist rooms including an art room, woodwork workshop, computer lab, library, music and drama centre.

Hugh Gemmell Lamb-Smith (1889–1951), an Australian educator who, as a member of the Second Field Ambulance unit, landed at Anzac Cove on 25 April 1915, taught at Tudor House in the late 1900s;[7] he was a member of the staff of Caulfield Grammar School, both as teacher and administrator, from 1913 to 1951.

The Tudor House War Memorial Swimming Pool was officially opened by Lieutenant-General Sir John Northcott on 9 December 1961.

Madame Marie France Goodwin taught at Tudor House School (1994–2004) in the old French room, located on the path under the gym.

In 2010 the boarding house – Medley – began a program of renovation, with open dormitories styled by Richard Allen and developed by Property Overseer Peter Burgoyne.

The new library includes a Scholarship Classroom, Staffroom, Lecture theatre with video conferencing, interactive whiteboards, small cinema, a computer lab and glass throughout connecting the learning environment with the Wilderness space.

The playground courtyard of the Infants area was renovated with a new sandpit, play equipment focusing on concrete pipes, logs and rocks, and a 1953 Vauxhall Ute (donated by Denham Construction).
