HBO+EMTB is built on the reputations of two successful architectural practices – Hoadley Budge Olphert and Edwards Madigan Torzillo Briggs. We are proud of the design traditions of the organisations from which we've come. The amalgamated practice of HBO+EMTB was established 1994. Hoadley Budge Olphert, a New Zealand firm, expanded into the Australian market through merger with the local practice of Edwards Madigan Torzillo Briggs. Both firms had amassed significant design legacies: HBO had been operating since 1912, and EMTB since 1945.
