What we do.


Our clients seek a professional opinion supported by a critical understanding of their requirements. Our expertise lie in successfully weaving the natural and built environment, communities, conceptual frameworks, planning regulations and building practices into every proposal, managing the conflicting needs of all components within each project from conception to completion.

Retail sits at a critical juncture between the Public, Private and Commercial sectors of our society. At Christiansen O’brien Architects, we seek to understand the nuances of this intersection within every design proposal, ensuring we cater holistically to the demands of each project.

Commercial environments make up a significant portion of the spaces we inhabit. The significance of these buildings shape the urban environment we live in whilst their interiors play a critical role in our wellbeing. We interrogate this relationship, utilising it in all commercial proposals.

Mixed Use & Residential

Our urban environment is enriched when multiple programs or uses interact synonymously. Christiansen O’brien Architects understand that a carefully crafted design proposal ensures this synergy, and provides a collective outcome beyond the development, that benefits all.

As our cities and townships continue to grow, understanding current urban design principles becomes integral to the way we shape our future. With staff experience across multiple major developments in Australia including the 2000 Sydney Olympics, we take pride in the responsibility of this task.

The environment we inhabit during our formative years is critical in our development as people and communities. Christiansen O’brien Architects take the upmost care when creating these environments and curating their conditions. With multiple education facilities under our belt we continue to appreciate and critique the impact our designs have on the future.

Industrial & Bulky goods

A core of the modern economic system is the industrial production of goods and services. These spaces require extreme attention to detail as concepts of productivity and efficiency are at the heart the design outcome. Christiansen O’brien Architects have successfully catered to a broad range of industrial projects and their requirements over many years.

We understand the profession we operate in to be a node within the multiple networks that create our built environment. As we shape this environment, it shapes us.
