Open Brief.

To commence the thirtieth annual conference of the Society of Architectural Historians, Australia and New Zealand (SAHANZ), held on Australia's Gold Coast in July 2013, ten delegates were invited, with very little warning, to take five minutes and one image and offer a provocation on the open matters of architectural history in the present moment. The term 'open' was taken as the conference theme--a device used by SAHANZ meetings not so much to define the scope of papers presented as to declare the conference flavour year by year. It was not, therefore, an open conference (anything goes) so much as a conference on open issues (where, indeed, to go). The ten interlocutors were invited after the conference to document their interventions. They are presented here as a record of the preoccupations of a specific moment and a specific institutional geography, with all the idiosyncrasies and commonalities it might reveal to a broader audience.
