A carriage house, the children's quarters in an attic, a pioneer tool shed, and a country store are all owned and operated by the Daughters of the American Revolution. The two-story house was built by Dr Caples, who came to Oregon Territory by wagon train in 1844 as a boy of twelve. It's a good example of an American pioneer home.

The Knapp Social Center is also located on the property. It is a separate building available for rent for receptions, family reunions, and more.
