The subsequent expansion

In 1991 the construction of a new south wing, designed by the Oxford Architects' Partnership, began. On the completion of the new Hall, kitchens, basement rooms and student accommodation in the second quadrangle, the room used as Hall since 1981 was converted into what is now the Saugman Common Room. A new meeting room, the St Cross Room, was also provided. The new buildings were completed for the beginning of Hilary Term 1993.  All this took place during the stewardship of the third Master, Richard C. Repp. The Master is flanked by Ruth van Heyningen (Founding Fellow), and the Rt Hon. Lord Jenkins of Hillhead (Chancellor of the University) at the Jubilee Dinner, held on 29 June 1990 to celebrate the first 25 years of the College.

After the College's move to St Giles in 1981, the College maintained ownership of the land and the two buildings on St Cross Road. For most of the time between 1981 and 1995 they were let to the Oxford Centre for Islamic Studies. In 1995 it was decided to develop the site for student accommodation, to be undertaken jointly with Brasenose College. The ‘wooden hut' was demolished in July of 1995, with the new St Cross Road Annexe opened on 25 September 1996 (see below).

A new agreement was drawn up in 2007 to give the College and Pusey House a new joint lodge and to rearrange some of the space of the St Giles site. It was signed on 17 October 2007. Celebrating this step forward are: Fr Jonathan Baker (Principal of Pusey House), Fr William Davage (Custodian of the Library, Pusey House), David Browning (Fellow), Andrew S. Goudie (Master).
