The house was built in 1717, and stands on land that has been in continuous ownership of the Denison family since 1654.

It is now owned and operated by the family-run Denison Society, and was added to the National Register of Historic Places on June 15, 1979.

It is a 2+1⁄2-story timber-frame structure, with a gabled roof, central chimney, and shingled exterior, and is set mainly on a rock ledge, with only a small basement area in one corner.

The interior follows a central chimney plan, with a narrow entry vestibule that also houses a winding stair.

The parlors have modestly carved fireplace paneling, and many rooms have original floorboards that are up to 2 feet (0.61 m) wide.
