Bonar Hall
Why it's listed
Bonar Hall is a two-story brick house on Dixie Avenue in Madison, Georgia, built in 1832 by John Byne Walker as the center of his large Morgan County cotton plantation. The house sits at the middle of a symmetrical layout, with a kitchen, orangery, pergola and privies arranged around it. Its exterior is plantation-made red brick, and the interior follows a plain Greek plan with a central hall and two rooms on each side. A lacy two-story Victorian veranda was added in the 1880s, replacing the original Doric portico. The estate has shrunk to about 100 acres and is a private residence. The nomination highlights the boxwood garden, planted by Eliza Fannin Walker, with cork oaks, mock oranges, yews, magnolias and other specimen trees, many from the original planting. It describes the property as one of the few surviving mid-19th-century gardens in Georgia and an important architectural landmark in Madison.
Significance in brief: The nomination calls it an important survivor of Georgia plantation life and an architectural landmark in a town of many such buildings. Its boxwood garden and plantings are described as one of the few surviving mid-19th-century gardens in the state. The house, its outbuildings and the garden together form a symmetrical, classically organized landscape.

What listing means for this property
National Register listing is honorary for a privately owned home: it does not by itself restrict what an owner may do with their own money, and it does not require public access. Restrictions come from local landmark or historic-district ordinances, which are separate (how they differ).
Owner-occupied houses are not eligible for the 20% federal rehabilitation tax credit, which applies to income-producing buildings, but many states offer credits for homeowners. Listing also opens the door to preservation easements and to buying a plaque. Start with what listing means for homeowners, renovating a listed house and selling one.
General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
