studioplusthree Llewellyn House

studioplusthree is an award-winning emerging architecture practice based in Sydney.

studioplusthree combines craft, innovation and attention to detail -   Wallpaper* Magazine Architect’s Directory 2018

Working across architectural, arts, and cultural projects, our work is focused on design that is contemporary, clean and simple, but rooted in a knowledge of craft and materiality. Our approach to projects is highly contextual, responding to the urban environment and informed by the surrounding landscape. We work closely with each our clients to produce work that is authentic, sophisticated and refined. The tactile, emotional and intellectual aspects of our work are key concerns of the studio, whether the project is an art installation, an exhibition design, or a residential project.

Founded by directors Simon Rochowski, Julin Ang and Joseph Byrne, the practice draws on their experience of working with a wide range of studios, clients and cultural institutions both in Australia and overseas. The studio approaches all its work using a common set of skills and values, to encourage interaction between different disciplines. 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. In 2018 the studio was nominated for the Dezeen Awards 'Emerging Architect of the Year', as well as selected for the Wallpaper* Magazine Architects' Directory - both publications featuring their selection of the top twenty emerging practices worldwide. The studio received the 2017 Australian Interior Design Award for Installation Design, a 2016 AIA NSW Architecture Award (Small Project Architecture) and Commendation (Residential Alterations and Additions).
