Our Story
AJC: A Practice Powered by People
AJC’s story is one of people—visionaries, collaborators, and community builders—who have shaped Sydney’s urban landscape with creativity, care, and conviction.
From its founding in 1956 by friends John Allen and Russell Jack, later joined by Keith Cottier, AJC has always been more than an architectural studio. It’s a collective of individuals who believe that great design begins with empathy and ends with impact. Today, that spirit lives on in a diverse team working across education, commercial, residential, and master planning projects—each one driven by a shared commitment to excellence and purpose.
Our people are our greatest asset. We are a culture described by our team as friendly, supportive, and collaborative. We want to celebrate wins together, support one another through challenges, and strive too continually do better. AJC is defined by the relationships we build and the people we empower.
At AJC, architecture is not just about buildings. It’s about the people who imagine them, the communities who inhabit them, and the future we shape together.
