The Roswell City Council has approved a plan to make an antebellum home there the oldest energy-neutral house in the country.

A new roof complete with solar panels could turn Mimosa Hall into a “net-zero” building, one that makes more energy than it uses.

The home was originally built in 1841 for John Dunwoody, whose son went on to found the city of Dunwoody, Georgia.
