Merchant's House Museum

The Merchant's House Museum, also known as the Old Merchant's House and the Seabury Tredwell House, is a historic house museum at 29 East Fourth Street in the NoHo neighborhood of Manhattan in New York City. Built by the hatter Joseph Brewster between 1831 and 1832, the house is a four-story building with a Federal-style brick facade and a Greek Revival interior. It served as the residence of the Tredwell family for almost a century before it reopened as a museum in 1936. The Merchant's House Museum is the only nineteenth-century family home in New York City with intact exteriors and interiors.

Brewster built the house as a speculative development and sold the house in 1835 to the merchant Seabury Tredwell, who lived there with his wife, eight children, four servants, and several relatives. Five of the children never married and, for the most part, lived at the house through the end of the 19th century.
