Central to the Michaelhouse experience, is the House system, with each House being home to approximately 65 boys.

There are eight Houses, each one in the care of a Housemaster who acts in "Loco Parentis." The Housemaster is supported by a management team consisting of a Senior Tutor, House Tutors, Home Room Teacher and a Prefect body. Together they are responsible for facilitating a nurturing and structured environment where every boy can feel secure and valued.

The Houses are the focal point of group identity, friendship and relaxation, and have a healthy rivalry in sporting, cultural and academic arenas. All Houses have comfortable common-rooms that have networked television facilities and table tennis or pool tables for relaxation.

Senior boys enjoy accommodation in duel or single bed-sits equipped with internet computer facilities. Junior boys (E to D Block) are housed in rooms of between 4 and 8 boys to facilitate their greater need for socialisation. All bed-sits and single rooms have built-in work areas for study and homework.

Michaelhouse operates on a four-term calendar. A generous leave system is offered each term which includes a four-day mid-term break, two weekend leaves, and Sunday and supper leaves as appropriate.

The school has a full complement of resident staff that facilitates a high level of pastoral care and individual attention for every boy. The well-equipped Medical Centre is staffed by three qualified full-time Sisters who are complemented by a medical doctor who consults daily at the school.
