One Spadina Crescent is a showcase for the city — a world-leading venue for education, research and public outreach on architecture, landscape architecture, and urban design. The revitalized site is the new home of the John H. Daniels Faculty of Architecture, Landscape, and Design.  The One Spadina project has double the space available to Daniels students and professors — to more than 100,000 sq./ft. — and built a far more visible platform.  The One Spadina Project was built in two overlapping stages (involving the existing 19th century structure, the new construction to the north, and the surrounding landscape). The Phase 2 extension connected to the existing structure has expanded the facility to a little over a 100,000 sq ft.  The newly added spaces include; classrooms, lecture halls, work areas, offices, and galleries. Over 50% of Level 2 and Level 3 are constructed with a bubble deck reinforced slab with imbedded radiant tubing for cooling and heating.  There is a large penthouse mechanical room, cooling tower room, and basement chiller room in addition to the Phase 1 mechanical rooms.
