studioplusthree is an award-winning emerging architectural design studio based in Sydney.


Working across the disciplines of architecture, exhibition and installation design, our work focuses on using the qualities of materials to produce work that is durable and memorable. The tactile, intellectual and emotional aspects of our work are key concerns of the studio, and we are interested in the roles of craft and innovation in helping to realise these qualities.

Founded by directors Simon Rochowski, Julin Ang and Joseph Byrne in 2014, the practice draws on their experience of working with a number of high profile studios, clients and cultural institutions both in Australia and overseas.

The studio aims to produce work that is rich, informed and diverse - employing a common set of skills and values between different project types, to encourage interaction and reduce boundaries between them. Our projects are undertaken in a spirit of collaboration and curiosity, and through a process of experimentation we seek to create projects that are distinctive and bespoke.

studioplusthree has been the recipient of a number of design awards, including the 2017 Australian Interior Design Award (Installation) and a 2016 AIA NSW Architecture Award (Small Project Architecture).
