A Michigan-based builder will construct a wing onto the home of Aimee Copeland, the Georgia woman who's been battling a flesh-eating disease.

Executives with Pulte Homes of Bloomfield Hills, Mich., say its workers and partners are volunteering to construct the two-story 1,956-square-feet addition to Copeland's suburban Atlanta home at no charge to the family.

Company officials say the addition, expected to be completed within 40 days, will include a new bedroom, a fitness room for rehabilitation and a study area.

The 24-year-old suffered a deep cut May 1 when she fell from a broken zip-line over a west Georgia river. She then contracted a rare infection called necrotizing fasciitis.

Doctors amputated her leg, foot and both hands. She's now recovering at an east Georgia rehabilitation center.
