Gabe Mercier, dean of trades and technology at Thompson's University College of the North campus, stands with Murray Oman, an apprenticeship and carpentry instructor, in front of a model of an equal pitch intersecting hip and gable roof that students at UCN built. The display was part of a set up UCN had at the City Centre Mall on Feb. 12 as part of the institution's Trades & Technology week from Feb. 7 to 13.
