Leffler Simes Architects (LSA) is well recognised as one of Australia’s leading architectural practices with offices in Sydney, Melbourne and Brisbane.

Established in the late 1960s, Leffler Simes was at the forefront of the dramatic expansion of the retail sector throughout Australia and designed a majority of the large shopping centres built at this time.

With a solid retail pedigree founded in the 1970s and 80s, Leffler Simes have maintained a role as a major retail practice since.

From the 1980s onwards, the practice evolved to encompass all sectors of the architectural sphere; retail, commercial, industrial, hospitality, education, medical, leisure and residential.

In response to an increased demand for our expertise, LSA established a Melbourne office in 2003 followed by a Brisbane office in 2010, with approximately 70 staff in total. Our success has been principally due to the quality of our people and their vast range of architectural creativity and ability. Add to that our large team of interior designers who actively assist all the sectors noted above.

The practice culture is energetic, multi-faceted and varied, thus enabling Leffler Simes to produce quality design solutions while providing a highly professional service to our clients. We are also environmentally conscious, commercially sound, and with strong social values aimed to benefit the communities in which we live and work.

It is our objective to continually evolve and develop as an architectural practice, always striving to create new and interesting solutions ensuring an architecture that embodies our client’s values and aspirations, as well as our own.
