Located at 28 The Green in Watertown is a house originally designed by noted builder/architect David Hoadley, although it has been much altered over the years. It was built in 1805 for Alanson Warren, Senior, first president of Wheeler & Wilson, manufacturers of sewing machines. One of his sons, Truman A. Warren, built a house across the street in 1851. Another son, Alanson Warren, Jr., inherited his father’s house and made substantial alterations to it in the Italianate style: large wings were added and a veranda that spanned the front facade. In the 1930s, the house was altered again in the Federal Revival style by architect Cameron Clark (pdf). The Italianate wings were replaced with smaller ones and the interior was completely remodeled. Clark also added the central entry porch.
