to extend the complex, in 1966, it again wished to build "on traditional lines", that is in period style. It wanted another three-storeyed wing to the north of the Castle Street range, perhaps meaning to complete the quadrangle. Its efforts to raise the necessary 80,000 pounds were unsuccessful. It decided instead to build three separate three storeyed residential blocks and commissioned one from Miller, White and Dunn, a Dunedin architectural practice. In the event only one was built, Nevill House, which opened on 4 March 1973. This is a small tower, immediately to the north of the Castle Street range and close to the street, of Modernist design. Its concrete framework is visibly expressed and it has red brick infills to contextualise it. A further extension was made with another free standing building to the north again, to house the library which was completed on 1 August 1976. It was called the Northcroft Library, after another generous donor and was designed by John Harrison (b. 1935). Amidst controversy the library was dispersed in 1988. This is another Modernist building but now in contrasting materials. The most dissonant structure in the group it has steeply inclined slab roofs and extensive areas of glazing. In 1988 too the first of three buildings providing self-contained flats was completed, Irvine House. Further to the north Millar House and Newcombe House were completed in 1989. These were all designed by Roger Dodd (1939–2001). Millar and Newcombe Houses face Dundas Street, the thoroughfare linking Castle to Cumberland Street at the north end of the city block containing Selwyn College. The two are linked to form an archway giving access to the quadrangle from the north. All three of these buildings are two storeyed and are finished in unpainted, rendered cement. Their forms are those of hipped roof houses. They are rather plain and the northward linked pair are set behind a brick wall along the street. In 1993 the archway of the Castle Street range was shut off for security reasons with a large glass wall incorporating a door of the same material. The view from the street to the All Saints chancel remained. It has since been eclipsed by the construction of a solid walled cross way joining the ground floor of each wing through the archway. Summary There are some other college buildings more or less integral to the group but the Castle Street
