Our story begins in 1993 when David Hillam, Hillam Architects’ owner and Principal, opened his doors to clients who were looking for a residential Architect who could offer distinctive, high-quality design.

David founded this firm on the belief that the quality of our built-environment, whether in the work-place, at home, or in the public spaces between, directly influences the quality of lives.

David’s passion for understanding how people use and live in buildings, as well as his exceptional eye for design and obsession with detail, established Hillam Architects as one of Perth’s leading design firms. Awards followed, and the business grew.

Having built an enviable portfolio over the past 20 years, Hillam Architects sees opportunity for extraordinary design at every scale, from multi-residential, mixed-use and commercial developments through to bespoke, high-end single residential dwellings. We aim to produce spaces that inspire, elevate and exceed the lifestyle expectations of the people who interact with them.

Directly responsive to the needs of the client, the parameters of the site and climate, our projects reinforce the role of architecture in creating a sustainable future.

Experience gained through working for and with developers, has ensured we’ve adopted a pragmatic, hands-on approach to our commercial projects. We welcome the challenge of combining the business needs of stakeholders and developers with our passion for producing buildings that are innovative, exciting and enduring.

Our practice in this area, coupled with our excellent relationships with local authorities, consultants and contractors, allows us to push the boundaries and ensure projects are delivered on-time and on budget, without compromising on quality or aesthetics.
