Leffler Simes Architects is committed to staying at the forefront of international design excellence.

We understand the importance of creative innovation and design ingenuity.

As part of our commitment to creating distinct, user-friendly spaces, we continually look for opportunities to adapt and refine conventional design and the planning processes.

Most importantly, we work hard to ensure that our projects define a clear and unique identity for our clients, whilst remaining mindful of budget and functionality constraints.

With the active involvement of our clients, we have won numerous awards for our work, including multiple accolades from the Master Builders Association of Australia.


We take a very reasoned and creative approach to Sustainable Design, with this aspect being an important part of every commission.

Our culture of professional education ensures that we are constantly renewing our awareness and knowledge of the impact that the buildings of today will have on future generations. We are a member of the Green Building Council of Australia and have many staff with an active interest in continual development of this area.

To this end, we seek to minimise the environmental impact of our buildings by enhancing the efficiency of the built environment through materials, energy consumption, services efficiency and development space in every design.


Our reliability is just one of the many reasons our loyal Clients keep coming back, time and again. Reliability is an essential attribute of the Leffler Simes approach.

Our hands-on management style and commitment to outstanding client service means that our clients have direct access to our Directors, Associate Directors and Project Architects for the entire duration of our commissions.
From inception to completion, we provide a reliable service that is carefully customised to meet the unique requirements of our individual clients and their projects.

“Leffler Simes have met every project deadline and milestone required of them in the course of our relationship including turn key projects where the desired project time, quality and budget were fixed.” Garry C. Zauner, Managing Director, Zauner Group of Companies
