It looks like I posted this building too late. It was demolished a few years ago! A new building was completed on the site in 2022.
Later home to a business and much altered, the building at 595 Greenhaven Road in Pawcatuck was once a restaurant called the Greenhaven Inn. I’m not sure when the house was built (if it’s Colonial or Colonial-Revival). The real estate websites give a date of 1901 but that may not be very precise.
