O’Neill Architecture offers a different approach to architecture for challenging and competitive times. We work beside our clients to achieve their success through all stages of the project.

  • Why


    When Justin O’Neill founded O’Neill Architecture, he saw a firm where its clients could access an enormous amount of expertise and intellectual property to create outstanding projects, uniquely one without the layers, delays and inefficiency of a traditional practice.

  • Pro Bono

    Pro Bono

    We contribute to non-for-profit organisations, universities and organisations as a way of broadening our community interaction and to promote ideas as a force within society.

  • Research


    Research is the starting point for every project. Understanding the site, it's connection with the City, the planning overlays and their opportunities, history and questioning current models of development are the platform for our processes. From this we build a narrative for the site, as explanation of what the site 'wants to be' and use this as a collective tool for engagement of all stakeholders.

  • Sustainability


    For us, sustainability and economy are inextricably linked. Economy in the use of materials, the need for air conditioning of spaces, embodied energy within material selections and maximising the recycling of materials and use of rain and recycled water.
