The Pearl S. Buck House at Green Hills Farm, an example of 19th century (built 1825[4]) Pennsylvanian architecture, is constructed of coursed fieldstone.

When Buck purchased the farmstead, she made extensive alterations and additions to the 19th century farmhouse, including a two-story fieldstone wing added to the east gable and two libraries.

Today, visitors can tour twelve rooms of the home and visit the pre-Revolutionary War cottage on the property and the barn built in 1827.

In the large library, two Pennsylvania jugs serve as lamp bases upon a hand carved Chinese hardwood desk, at which Buck wrote her breakthrough novel The Good Earth.

In May 2020, Pearl S. Buck International's project of developing and implementing the Taking Action tour was named a 2020 recipient of the Award of Excellence by the American Association for State and Local History (AASLH).
