The Hartley House is recognized for its Gothic Revival architecture and its occupants.

This house is an example of Gothic Revival’s more developed phase, with the high-pitched roof being a good display of Gothic Revival style. It also has some High Victorian elements, such as the intricate patterns carved into the eaves and above the windows. A trio of hornbeam (ironwood) trees stand on the lawn. This species of birch tree has long been important in the development of tool handles, mallets, and vehicle parts in eastern North America. 

The house was originally occupied by one-time deputy sheriff of Woodstock, William W. Hammond, and his wife, Rebecca. Following Hammond's death in 1890, Rebecca sold the house to her nephew, J. Chipman Hartley, in 1894. J. C. Hartley and his sister Mary had grown up in the house after the deaths of their parents. Hartley was a lawyer by trade, having studied with L.P. Fisher and A.B. Connell, as well as the long-time town clerk and town solicitor. He died in this house in 1934.
