About a quarter of single-family, detached homes in Vancouver are at risk of being torn down between now and 2030 due to rising land costs, predicts University of B.C. architecture professor Joseph Dahmen.

He developed the “teardown index,” which compares the value of a residence to the value of the overall property, also known as its relative building value (RBV). The lower this RBV, the more likely a house will be torn down and replaced by a new one.
