This unique structure was built in 1927 by Puget Sound Power and Light Company (now Puget Sound Energy). It is in a charming French eclectic design and is designed to hide a substation. A substation steps up or down voltage delivered to the site by transmission or distribution lines. The substation still exists at the site, but has grown in size to spill out into the adjacent area. According to the heritage inventory, “the structure is an especially attractive one for a utilitarian use and Puget Power sources identified it as being unique.”
