Bull O’Sullivan Architecture ( B/OS )
The Auckland-based Bull O’Sullivan Architecture (B/OS) practice was formed in 1994 when Andrew Bull and Michael O’Sullivan, having recently returned from practice in Europe and Asia respectively, decided to combine forces to attend to the larger projects coming into the B/OS practice. Glenn Watt joined in 1999 after a long and expansive career as a sole practitioner. The portfolio of work demonstrates an extensive array of projects with national and international clients spanning a broad spectrum of budgets and building technologies. The firm consists of three principals and three architects, and eight graduate architects/model makers.
