The renovation and expansion of One Spadina Crescent for the University of Toronto's John H. Daniels Faculty of Architecture, Landscape, and Design (DFALD) embodies a holistic approach to sustainable design... Design strategies were multifaceted to address environmental, economic, and social values. One example of this is the new, dynamic ceiling on the third floor of the new addition. Using the cantilevered structural logic of the Firth of Forth Bridge, the ceiling of the studio is shaped to integrate daylighting, hydrological control, and structural optimization, creating a desirable space that engages the senses while simultaneously saving energy and water and serving as a pedagogical tool. For years, many initiatives have attempted to preserve, reuse, and repurpose One Spadina Crescent. This project has revived the site and offers a north face for the first time in its history. The preservation of the north addition will have value in how it establishes a dialogue with the urban and campus context and serves as a critical piece of infrastructure for the city of Toronto.
