Building Director Tim Williams called out safety instructions to dozens of volunteers Monday morning from his perch on a muddy mound adjacent to a home under construction. Another month or two and this home will be complete, Williams said, the third in a 21-lot subdivision development in Gainesville known as Copper Glen, which came into the hands of Habitat for Humanity of Hall County as a land donation. Katie Deal, an award-winning dancer, singer and actress, listened closely to the commands.
