Originally a garden, the demand for more accommodation for undergraduates in the early 18th century resulted in two free-standing blocks being built. The first block erected was the Robinson Building on the east side, built in 1720 by Bishop Robinson at the suggestion of his wife, as the inscription over the door records. Its twin block, the Carter Building, was erected on the west side in 1729, as a result of a benefaction by Provost Carter. The two buildings stood for nearly a hundred years as detached blocks in the garden, and the architectural elements of First Quad are repeated on them — only here the seven gables are all alike. Between 1817 and 1819, they were joined up to First Quad with their present, rather incongruous connecting links. In the link to the Robinson Building, two purpose-built rooms have been incorporated – the Champneys Room, designed by Weldon Champneys, the nephew of Basil Champneys, and the Benefactors Room, a panelled room honouring benefactors of the college. A Gothic oriel window, belonging to the provost's lodgings, was added to the Carter Building in 1826.
