WILLIAMS BOAG architects (WBa) is a Melbourne based architectural firm providing expertise in the fields of architecture, planning, urban design and interior design. WBa was established in 1975 and has built an enviable professional reputation based on carefully designed and finely crafted architectural solutions. 


WBa practices with an alignment of purpose, personal commitment and accountability, and share one common goal: the provision of fit-for-purpose design solutions from concept to hand over. Clients enjoy responsiveness, personal commitment, and agility in project delivery brought to their project.

WBa's commitment to a sustainable future is without question. The company's approach to responsible design is to address sustainability in an holistic manner through all project typologies acknowledging the different facets of sustainability - social, cultural, ecological, and economic and responding to the various challenges with a considered approach to their impact on the design and delivery process.​

WBa's design approach starts by addressing sustainability issues and opportunities in the concept or master-planning phase of any project which leads into consideration of the environmental impacts generated by the selection of building systems and services, the choice of materials, and the application of passive and active design strategies.
