It was built for John H. Walsh, who ran the adjacent family paper mill.","why_significant":"The nomination argues the house is a locally significant, relatively intact example of 19th-century domestic design in the New Windsor area. Its original center-passage, double-pile plan and Greek Revival interior finishes largely survive, including marble mantels, plasterwork and the main stair. It is also an important link to the Walsh family's mill development along the Quassaick Creek corridor.","narrative":"Built around 1835 on a 2.06-acre parcel beside Quassaick Creek in New Windsor, this brick house was the residence of John H. Walsh, who oversaw the neighboring paper mill established by his father, Hugh Walsh. The house began as a one-and-one-half-story, hip-roofed Greek Revival building with brownstone trim and a three-sided porch of Grecian Doric columns. By the later 1850s the Havemeyer family lived there, and the main block and service wing were raised to full two stories. Inside, the center-passage, double-pile plan survives, along with black marble mantels, plaster ornament resembling the work of Minard Lafever, the original stair and the kitchen hearth. Pressed-tin ceilings were added around 1910. The porch columns have since been replaced by chamfered piers. The house is recognized as a locally significant, largely interpretable example of Greek Revival domestic architecture and as a reminder of the Walsh family's mill enterprise.","period_of_significance":"c. 1835-c. 1910","architect_builder":null,"architectural_style":"Mid-19th Century: Greek Revival","criteria":["C"],"status_note":"Historic and current function are both listed as single dwelling; a catering hall is also listed in the function section.
