Edge Hill, also known as Green Hills and Walker's Ford Sawmill, is a historic home and farm located in Amherst County, Virginia, near Gladstone. The main house was built in 1833, and is a two-story, brick I-house in the Federal-style. It has a standing seam metal gable roof and two interior end chimneys. Attached to the house by a former breezeway enclosed in 1947, is the former overseer's house, built about 1801. Also on the property are the contributing office, pumphouse, corncrib, and log-framed barn all dated to about 1833. Below the bluff, adjacent to the railroad and near the James River, are four additional outbuildings: a sawmill and shed (1865), tobacco barn, and a post and beam two-story cattle barn (c. 1947). Archaeological sites on the farm include slave quarters, additional outbuildings and a slave cemetery.

It was added to the National Register of Historic Places in 2008.
