In the 1960s, the college took steps to consolidate its site on North Bailey, with the houses at the junction of Bow Lane and North Bailey being demolished in 1961 to enable the construction of a new dining hall and quadrangle, designed by neo-classical architect Francis Johnson.
These new buildings were joined to existing 18th century houses at 16–18 North Bailey to form the present Main College.

In 1965, the college's original home on South Bailey was exchanged with neighbouring St John's College for 22 and 22A North Bailey (now Grads House) which with other purchases gave the college a 95m-long frontage on North Bailey.
