TRIAS is an emerging architecture studio based in Sydney, Australia. Since its establishment in 2016, TRIAS has quickly developed a reputation for thoughtful and thorough design work.

The studio is founded on three principles: to create buildings that are solid, simple and beautiful. These ideals tie our work to the origins of architecture, which Vitruvius defined as firmness, commodity and delight.

TRIAS is currently completing projects across Australia, and has received recognition in numerous local and international competitions.  

Our studio has a strong design ethic and process. Our work is rhythmic, rigorous and materially expressive. We craft spaces with light, scale and volume, and produce architecture that is sculptural and calm.



TRIAS seeks simplicity and integrity within the built environment. We work closely with our clients to make buildings that reflect our shared values.

We are passionate designers who firmly believe that well designed spaces enrich people’s lives. We believe in quality over quantity, and advocate for less but better in all that we do.

Our work aims to inspire its occupants, and to quietly provoke change in our cities, suburbs and landscapes.
