Cascading down a rocky slope in West Vancouver, the home was a creative effort that required patience and a tolerance for loss.When you build a home from the ground up, there’s one thing that’s more important than the concrete, the lumber, the steel or nearly anything else: patience.

For Jack and Araxi Evrensel, that became abundantly clear when they began start-and-stop work on a house that clings to a steep slope of granite at the edge of Burrard Inlet, in West Vancouver, Canada. By the time the house was completed, they had spent eight years working on it, with three different architects.

The couple tried to take each delay in stride. “We took our time, because we weren’t in any rush,” said Mr. Evrensel, a former restaurateur who sold his five upscale British Columbia restaurants in 2014.
