[1] The Josiah Wilcox House is located in a residential area of central western Greenwich, on the west side of Riversville Road north of its crossing of the Merritt Parkway.

The building's most prominent feature is its impressive Greek Revival temple front, consisting of four fluted Ionic columns supporting a triangular gable pediment.

The interior retains many original features, including the main staircase, and fireplace surrounds.

It has been little-altered since the late 19th century, and is one of Greenwich's finest Greek Revival buildings.

Wilcox was a prominent local businessman, operating a factory on the nearby Byram River that manufactured tinning tools and carriage parts.
