The original Greek Revival block dates to about 1840, and an Italianate rear addition and remodeling followed about 1870.","why_significant":"The nomination argues the house is a rare surviving early brick residence in Black Rock, and one of only three 19th-century brick residences there to remain eligible after a 2010 survey. It shows a transition from Greek Revival to Italianate styling that mirrors the neighborhood's growth after the Erie Canal and its later industrial prosperity. Its interior remains largely intact, and later alterations are described as reversible.","narrative":"Built around 1840 on Dearborn Street in Buffalo's Black Rock neighborhood, this brick house began as a Greek Revival residence with a side-hall plan, stone lintels and a sidelit entry. About 1870 a rear kitchen block and Italianate brackets were added, and the roof was reconfigured, possibly after a fire. Its early residents included Lewis Dayton, a physician who later served as Buffalo's mayor, and later Warren Henry, a superintendent at the Buffalo Malleable Iron Works, who probably commissioned the remodeling. Inside, the original layout, plank floors, mantels, staircase and trim largely survive. A later dormer and portico have affected its appearance, but they are considered reversible. A 2010 neighborhood survey found it to be one of only three remaining eligible 19th-century brick houses in Black Rock. It was listed for its architecture, as a rare example of early brick housing that reflects the area's canal-era and industrial growth.","period_of_significance":"c.1840 - c.1870","architect_builder":null,"architectural_style":"Mid 19th Century: Greek Revival, Italianate","criteria":["C"],"status_note":"Still used as a single dwelling.
