[1][2] One of the essential elements of his early works is his employment of striking interior atrium space, which became widespread on an international level during the 1970s.
These included structural and mechanical services (most notably, exposed air-handling ducts), as well as aspects that ease movement and communication.
[1] This was exemplified in the McMaster University Health Science Centre, his breakthrough project,[3] which was meant to resemble a large construction set for children.
He envisaged Toronto Eaton Centre – which opened on February 10, 1977[4] – to be an "interior street" instead of being simply a shopping mall.
[5] Two of the structures his firm designed for the University of Maryland Medical System in Baltimore were meant to connect the passing from the 20th to the 21st century.
For instance, the Student Learning Centre at Ryerson University (2015) featured a green roof and energy efficient lighting on the exterior.
Likewise, The Bow in downtown Calgary employed an energy efficient glass facade, interior atria, and roof gardens.
[1] Zeidler rarely designed private residences, drawing up approximately 20 in his career, most notably the four-storey home in Rosedale that he constructed for his family during the late 1960s.
