(b) The association of the place with events, persons, or ideas of importance in New Zealand history:
The Flats have special significance as a major early project in Miles Warren's career that allowed full and free articulation of his architectural concerns and the formulation of the influences he acquired while working in Europe. Warren has been recognised nationally and internationally as one of the most important New Zealand architects of the second half of the twentieth century.
(e) The community association with, or public esteem for the place:
At its construction, 'Fort Dorset' bemused the Christchurch community for its unconventional use of materials and aesthetic approach, and was once reputed to be the ugliest group of buildings in the city. However, the Dorset Street Flats soon became greatly admired in architectural circles, and many prominent New Zealand architects have lived in the Flats. The Flats continue to attract national and international interest as a resolved statement of a new direction in post-war domestic architecture, and the Dorset Street Flats are now well-known and highly regarded among Christchurch residents.
