The Cabin at Longbranch is not merely a home—it is the story of a life devoted to architecture, nature, and patience. Designed and personally built by architect Jim Olson, founding partner of Olson Kundig, the project began in 1959 as a 14-foot-square bunkhouse, when Olson was just 18 years old. Over the course of 55 years, the structure underwent thoughtful renovations and expansions, culminating in a 1,200-square-foot weekend retreat perched on the edge of Puget Sound and nestled among towering fir trees.
