Living out became compulsory for students for at least part of their career, and many existing buildings were either rebuilt or refurbished to make room for students: The Rectory was remodeled, C & D Stairs were refurbished, the Main Hall was repaired, and Jevons' was redecorated. A Middle Common Room for the postgraduate community was added in Kitchen Stairs. In 1981, the Formal Ball was renamed 'The Lion in Winter', which it has been called ever since.
