Practice Ethos

Card Practice is an architecture and urbanism practice that works across a range of scales and typologies, with a focus upon the design of buildings, interfaces, and public spaces. A collaboration between Tahj Rosmarin & Jimi Connor, the practice has over a decade of combined experience working across a variety of scales and programs- from small public interventions, residential dwellings, and precinct masterplans.

Though each project is unique and tailored to each specific client or user, CARD’s work is focussed on creating site-responsive, no-frills architecture with a strong understanding of place, context, and environmental conditions. 

Minimising the environmental impact of each project is a strong focus: and selecting appropriate materials, understanding the lifecycle of the building, and embedding passive design principles, is an important part of the design process.

Critically, CARD’s work is about people. They offer a humanistic approach to design that considers the way people use and interact with space.
