After making do in temporary quarters for the first year or so, first in a store and then in St. Cuthbert's House, in November, 1919, the Qu'Appelle Diocesan School for Girls moved into the building that, for almost all of us now living, means "the School" - at 1601 College Avenue in Regina.

Its history really begins in 1911 when the Diocese of Qu'Appelle bought from the city, for $30,000, the 15 acres bounded by College Avenue on the north, St. John Street on the east, Broad Street on the west, and 117th Avenue on the south (a later acquisition extended the property as far south as Broadway). It was planned to construct a number of buildings, including a Cathedral. The Cathedral was never built, but in due course there were 5 buildings on the site. (In addition to the School, these were the Old Synod Office, now known as Anson House, built in 1912; St. Cuthbert's House, built in 1912 to house the headquarters of the Railway Mission; the Maple Leaf Hostel, built in 1925 as a hostel for teachers and working women, now called Harding House; and the Bishop's residence, Bishop's Court, built in 1926).

Special legislation was passed exempting the property from taxation by the city, and the City of Regina provided a grant of $15,000 for a building fund. In August, 1913, the cornerstone for the building intended as a theological college to train priests for the Diocese was laid by Bishop Harding, at a service which included 300 Freemasons and the Regina Boy Scouts' Brass Band. The building was designed by the Montreal architectural firm Brown and Vallance, with Storey and Van Egmond as local supervising architects and R. J. Lecky as general contractor, for an estimated cost of $90,000. The Regina Leader described the new St. Chad's College as "of that design which seems to best give expression to the highest instincts and the noblest endeavors of the Anglo-Saxon race - the Early English." The building was constructed of solid brick with tapestry facings and ornamental terra-cotta, on concrete foundations with a granite base course. The long main building, 175 feet by 95 feet and 3 stories high, was anchored at the east end by a north-south wing, also 3 stories high; and at the west end by St. Michael's Tower, which rose to 4 stories, and the adjacent Chapel.

The Chapel, first known as the Bishop Burn Memorial Chapel, and later as St. Chad's Chapel, was an integral part of the School's life throughout its history, used daily for Holy Communion and for the morning chapel services with which each schoolday began. It featured terra cotta statuary, depicting St. Chad, Bishop of Lichfield, in niches high on the east and west exterior walls and, at the southeast corner where the Chapel met the main buiilding, a little terra cotta angel known to generations of QDS/St. Chad's girls as the Guardian Angel. On the interior, plain plaster walls were furnished with a number of pictures that were gifts of Miss Iram Briggs of England - "The Supper at Emmaus", "The Transfiguration", "The Crucifixion", "The Presentation of the Magi' and "Christ in the Carpenter's Shop". The altar and reredos were in memory of the men of St. Chad's College who were killed in the First World War. Over the years, memorials to the bishops of the Diocese and a plaque recognizing the Sisters of St. John the Divine were installed in the Chapel.

The theological college opened in June, 1914, but the First World War began almost immediately, and during the war years the building was used as a convalescent hospital for wounded soldiers. In November, 1919, the girls' school, which was overflowing St. Cuthbert's House, traded places with the theological college, in what was supposed to be a temporary move until a girls' school could be built. As it turned out, the theological college never moved back into the building that had been constructed for it. St. Chad's College stayed at St. Cuthbert's House until 1951, when it moved into the Maple Leaf Hostel. (The Fellowship of the Maple Leaf, which started work in Canada in 1917, was founded in England to provide teachers for Canadian schools, especially in the West. During the Depression years, the Hostel had provided a home for Anglican teachers in training and working girls needing accomodation and, during World War II, to women serving in the RCAF). St. Chad's College stayed in this building until in 1965 it moved to Saskatoon to form part of what is now the College of Emmanuel and St. Chad. At that point the building, renamed Harding House by Bishop Jackson in memory of Bishop Harding, was taken over as a residence for division three by the girls' school, which had itself been renamed St. Chad's School for Girls.

The School closed in 1970. In 1975 St. Chad's School, along with most of the other buildings on the property, was sold to the provincial government, which designated it a Provincial Heritage Property in 1980. In 1992 the City of Regina awarded it a Municipal Heritage Award for some exterior restoration which had been done. The property is currently managed by the Saskatchewan Property Management Corporation, and the St. Chad's School building is occupied by Child and Youth Services. However, the entire former diocesan property has been subject in recent years to increasing crime and vandalism, and the buildings have experienced some deterioration.

A comprehensive mixed-use plan for the diocesan site, which would have incorporated the old School buildings,  was proposed by a non-profit organization in 1998, but the project was not able to obtain the necessary support.   In the spring of 2005 the 20-acre property was sold  for “high-end” residential development. Although detailed proposals for the development are not yet available, all 5 buildings on the site have provincial heritage designation, which means that plans for their alteration or adaptive reuse must obtain provincial approval.

St. Chad’s Chapel was stripped of all its furnishings and deconsecrated on June 28, 2005.
