On one Sunday each spring, he would open the grounds to the public for them to enjoy. The Endicott House was designed by Charles Adams Platt. The Endicotts were involved in every step of building and decorating the home. They commissioned Italian painters to create the intricate designs on the living room's beamed ceiling and imported marble fireplaces for each room. Upon completion in 1934, Mr. & Mrs. Endicott moved in with their two children, Bradford and Priscilla Endicott, and Martha Endicott, Mr. Endicott's daughter by his first wife, Martha Barron, who had died in childbirth. Today the house retains much original character and artwork, antiques, oriental rugs, and Flemish tapestries donated by the Endicott family. Endicott's father, Henry Bradford Endicott was the founder of the Endicott Shoe Company, which maintained a sales office in Boston and a manufacturing plant in Endicott-Johnson City, New York. His grandfather was Augustus Bradford Endicott, a businessman and state and local official, and his sister was Katherine Endicott, who left the Endicott Estate to the Town of Dedham.
