About us

o2 architecture is a multi-disciplinary design practice specialising in the design and delivery of bespoke architectural and interior commissions throughout Sydney.

Our style is not defined, rather it responds to the relationship we develop with our clients, their specific needs and the qualities unique to each individual project. The results are collaborative and creative response tailored specifically for each brief. 

Our work encompasses a diverse range of commissions for the residential, commercial, hospitality and health sectors for both public and private clients. We have extensive experience with residential design, including alterations and additions to existing dwellings, new-building residences and multi-unit developments. 

o2 architecture is led by Stefan Lombardo who brings extensive design and construction knowledge from a diverse range of project experience throughout Australia and abroad.
