Biddle House (St. Georges, Delaware)

Biddle House, also known as the Vandergrift-Biddle House, is a historic home located near Port Penn and St. Georges, New Castle County, Delaware. The house underwent five distinct periods of growth and in the process has grown from a one-room-plan plank house to an extended rambling two-story structure. The earliest section was built about 1780, with the first modification made in the early-19th century. It was later expanded during the Victorian era with wings.

It was listed on the National Register of Historic Places in 1978.
