From the website of the builder and designer, Dirk Nelson:
Nelson had collected a treasure trove of Walla Walla valley history … Among the collection were beams & bolts from the old Louisiana Pacific mill to enormous light poles from the Columbia River’s McNary Dam. Railroad trestle girders lay stacked beside huge locust tree wood taken from the actual home site. With meticulous hand work, Nelson and his team, Living Space Construction transformed the boneyard finds into structural components that each hint at the story of their former lives.
