It stands out for its limestone-columned porch, terrace with balustrades, fine brickwork and stone trim, and an elaborate, largely unaltered interior.","narrative":"Built in 1909-1910 at 610 West Washington Street in Sandusky, Ohio, this two-story Classical Revival house was erected by builder George Feick for John Mertz, a successful stove and tinware merchant. It has a tall rock-faced limestone foundation, buff brick walls with sandstone sills and lintels, a wood cornice with modillions, and a slate hip roof with dormers. A broad masonry terrace with a balustrade leads to a porch carried on solid limestone Tuscan columns. Inside, the principal rooms keep their fireplaces and woodwork in mahogany, oak and yellow pine, along with a grand stairway, stained glass windows, an original bathroom, a cistern and a dumb-waiter. Feick also built the Ohio Soldiers and Sailors Home and many Oberlin College buildings. Compared with his wood-built houses in Sandusky's finer neighborhoods, this brick house for a merchant shows a different side of his work. It is valued locally for its architecture and its remarkably intact condition. The house now serves as offices.","period_of_significance":"1909-1910","architect_builder":"Feick, George, Builder","architectural_style":"Classical Revival","criteria":["C"],"status_note":"Historically a single dwelling; now used as commercial offices.
