The back yard contains a long brick outbuilding, which is one story high and has a pitched roof. The total area of the nominated property is 4.3 acres (1.7 ha).The inn was originally built as a farmhouse by Thomas Griswold Mather, who married his first cousin Jane Ann Mather in 1834. His wife died in 1853, at which point he sold the farm and the buildings to the town of Middletown. At that time, there were 35 acres (14 ha) in the farm, with an additional 16 acres (6.5 ha) in a wood lot. The town operated it as a poor farm until 1946.
