Dayton, Ohio largest abandoned mansion: 28 room, 8.5 baths

Built in 1909, this Jacobethan style building stands out. The property was added to the National Register of Historic Places in 1984. It was designed by Dayton architect Pretzinger. The home features 24 rooms and 8 1/2 baths. The Jacobean style generally defines Tudor Revival architecture between 1895 and 1915. It is based on more formal, late-Medieval English building traditions, including the Jacobean architecture popularized in the late 16th and early 17th centuries. However, it's not a pure Jacobean design. Its main characteristic of the style is the parapet gable, prominently featured to the left of the main entrance. Even more eye-catching is the larger half-timbered gable, rarely found on Jacobean houses. The owner died just six years after the house was built. The house was then sold. During the housing shortage of World War II, the third-floor ballroom was converted to six bedrooms and occupied. The home received a complete rehabilitation and remodeling in the 1980s. However, all of that renovation has been largely destroyed.
