O’Neill Architecture was formed in 2009 by Justin O’Neill.

Justin O'Neill


This followed 17 years as a Founding Director of Arkhefield. Justin, with his partners, grew this practice to be one of the significant practices in Australia. Justin’s projects have been the recipient of over 50 local, state and national awards. In 2009, Justin decided that there was an opportunity to approach architectural practice in a fundamentally different way.

Changing times need changed approaches. O’Neill Architecture is a tight studio. We work on a broad range of projects. Our project work encompasses public, commercial, retail, aged-care, retirement, multi-residential and residential buildings. Urban design and masterplanning figures prominently in the firm’s workbase. We are also committed to small residential projects as a source of inspiration.

We believe that architectural expertise needs broad inputs to be relevant. To this end, we maintain a meaningful research base working with University Masters programs on yearly projects, are actively creating prototypes for new buildings, and engaging in new procurement methods to create value for our clients.

We think of ourselves as sitting on both sides of the table at our meetings. One part of us imagine ourselves on the same side of the table as you, making the hard decisions, leading negotiations with council, taking responsibility for program and the project feasibility, driving and tuning the outcome for maximum value. We are also on the opposite side of the table, responding to your challenge to create something unique that will excite the market, test the rules, cost the least and make the most return. WE see this tension of roles as the juice that creates energy in projects and drives the best outcome for all, including our clients and ultimately the city and its inhabitants.

Importantly we recognise that the path to success is only partly driven by design, our people skills are just as important. We focus on:


  • • Great relationships with Planning Authorities
  • • Negotiation as a tool to achieve the best outcomes
  • • The entire outcome of a project
  • • A deep understanding of the marketplace
  • • Detailed strategic planning
  • • Direct and meaningful client service
