The Centennial College in Toronto will soon make history with the addition of Canada’s first net-zero carbon, mass timber college building. Designed in collaboration with construction services company [EllisDon](https://www.ellisdon.com/) as well as architecture firms [Dialog](http://www.dialogdesign.ca/) and [Smoke Architecture](https://www.smokearchitecture.com/), the Progress Campus A Block expansion building will also be notable for its emphasis on indigenous culture-inspired design. The $105 million project is expected to open in 2023.  Established in 1966, [Centennial College](https://www.centennialcollege.ca/) is [Ontario’s](https://inhabitat.com/tag/ontario/) first public college and primarily serves the eastern portion of the Greater Toronto Area with five campuses. The proposed net-zero carbon building has been conceived as a new gateway structure for Centennial’s Progress Campus and as an expansion of the A Block building to provide over 150,000 square feet of new and renovated space to help meet the anticipated growth in student enrolment.
