It is a vernacular double house and now contains apartments.","why_significant":"The nomination argues the house is a very early double limestone dwelling. It was built by Eleutheros Cooke, one of Sandusky's first citizens and a promoter of the Mad River and Lake Erie Railroad, the first railroad in Ohio. William Robertson bought it from Cooke's estate in 1865 and lived there almost thirty years.","narrative":"Built around 1835 at 412 Columbus Avenue in Sandusky, this two-story limestone house is an early example of a double dwelling. Its walls are rock-faced ashlar on a limestone foundation, with a gable roof, cornice brackets, stone lintels and sills, and a transom over each of the two front doors. The above-ground basement windows have lintels made of six-ended stone blocks. Later changes include alterations to the double front stairs in the late 1940s, cement over the side wall, and replacement of the original windows with double-pane glass. Eleutheros Cooke, one of Sandusky's first citizens and a promoter of the Mad River and Lake Erie Railroad, the first in Ohio, built the house. William Robertson bought it from Cooke's estate in 1865 and lived there for almost thirty years. He was the last person to own all three connected houses in the row. The block, on Sandusky's main street, is congested, and its former single-family houses now serve as apartments and offices.","period_of_significance":null,"architect_builder":"Eleutheros Cooke (builder/original owner); form also lists \"W.
