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 in 1831 and 1832, the edifice is a four-story building with a Federal-style brick facade and a Greek Revival interior. It was the Tredwell family's residence for almost a century before becoming a museum in 1936. The Merchant's House Museum is the only 19th-century residence in Manhattan with its original exterior and interior intact.

Brewster built the house as a speculative development, selling it in 1835 to the merchant Seabury Tredwell, who lived there with his family and servants. The structure remained in the family until the death of the youngest child, Gertrude, in 1933. George Chapman, a distant relative, purchased the building and transformed it into a museum. Over the next three decades, the museum's operators struggled to obtain funds to restore the deteriorating house. The architect Joseph Roberto completely renovated the building from 1970 to 1980, and the museum underwent further restoration in the early 1990s after the demolition of nearby buildings damaged it. During the 2010s and 2020s, museum officials protested the construction of a nearby hotel because of concerns that the project would further damage the house.
