Born in Sydney, Penny studied at Ascham School and the University of Sydney, where she developed a strong interest in sustainable architecture and urban design. She began her career in 1986 at the NSW Government Architect’s Office, contributing to several landmark projects with a focus on environmental responsibility. Between 1987 and 2002, she worked in London in the offices of Tony Meadows, Nicholas Grimshaw, and Richard Rogers, gaining exceptional experience across a range of high-profile projects.

In 1993, Penny joined Foster and Partners — one of the world’s leading architecture practices — working across their German and London studios until 1999. After returning to Sydney in 2000, she worked as an architect within the property industry, developing a sharp understanding of the commercial side of the profession.

In 2002, she co-founded Collins and Turner with Huw Turner, which has since become one of Sydney’s most respected architecture practices. Together, they oversee all aspects of the practice’s work, with a consistent focus on quality and sustainability.

Penny is a registered architect in NSW and a recognised voice in the profession. In 2020, she was appointed by the NSW Government Architect to the State Design Review Panel and to the Randwick Council Design Excellence Advisory Panel.
