The house accordingly became known as Parson Hare’s house or Chichele. In 1882 Canon Stanford was appointed the first full-time principal of the upper department, and in 1885 he supervised its move from the school precincts to an independent site at the corner of Rolleston Avenue and Cashel Street. Within a year the new house was being referred to as ‘College House’, being the house where the university students of Christ’s College resided.
New buildings were bought and built during the next eighty years, allowing the size of the House to expand slowly. There were 20 men in residence in 1911, 50 men by 1929, and 75 when College House marked its centenary in 1950. In 1957 College House became fully independent of Christ’s College. The endowments of the upper and lower departments were divided, and a separate Board was formed to govern what was renamed Christchurch College in accordance with the original resolutions of 1850. This name lasted until 1981, when the College reverted to the more popular College House.
The University of Canterbury’s decision to move from the centre of Christchurch to the considerably more spacious Ilam site forced the College to do the same. In 1965 the Archbishop of Canterbury (Dr Michael Ramsay) blessed the new site, and in 1966 students moved into the new buildings. Set in park-like grounds with extensive lawns and trees, the College’s white concrete block buildings were designed by Sir Miles Warren and won the Institute of Architects’ Gold Medal.
Together with St John’s College, Auckland, the College continued to provide theological training until 1970. Theological teaching continued on site until 1994, when the College House Institute of Theology was established. In 1990 the College admitted its first women students and appointed its first principal who was not a clergyman. Perhaps appropriately, the new principal (A.M. Brough) was a former Headmaster of Christ’s College.
College House today is home to 152 students from all faculties of the University. The College celebrated its 150th anniversary in October 2000.
A book on College's history, New Zealand's First University College, is being completed. The College is planning a series of alumni functions to coincide with the book's publication.
