The farm includes 100 acres (40 ha) of land north of United States Route 50, with its building complex anchored by a farmhouse built in 1847 and repeatedly altered.

The main portion of the farmhouse is a 1920s three-story Classical Revival block, which has the original 1847 two-story Greek Revival house attached as an ell to one side, along with another c. 1840 structure that may have functioned as a separate kitchen.

During the American Civil War, Oakham was where the irregular Confederate Army unit known as Mosby's Rangers was organized.

[3] The farm was listed on the National Register of Historic Places in 2016.
