The two William Floyd houses are believed to be the only surviving homes in New York of signers of the Declaration of Independence. The Mastic home is "reputed to be the best preserved and oldest manor house" in its part of Long Island.[2][3]
It is located about 0.29 miles (0.47 km) south of Washington Avenue and Wavecrest Drive in Mastic Beach. The home was built by Nicoll Floyd, who was William Floyd's father, and was given to William's son, also named Nicoll Floyd. The house was visited by Marquis de Lafayette and others.[2]
