Gordon’s Fireplace Building, the graffiti-covered ruin perched above Interstate 84 at 33rd Avenue, is set to be sold at a three-day auction starting Oct. 14, according to an offering document from SVN Imbrie Realty and Ten-X. In 1990, Gordon’s Fireplace Shop moved in. Aircraft Factory LLC, backed by Boyce’s Interurban Development, paid $2.7 million for the property in December 2017, 18 months after Gordon’s Fireplace Shop closed. Starting bid for the building is $225,000, the offering document says. “The Aircraft Factory, also known as Gordon’s Fireplace Building, is a unique development opportunity at 3300-3324 NE Broadway Street in Portland’s historic Hollywood District,” the offering document says.
