For more than a decade, Garth Brooks and Trisha Yearwood have been swinging hammers and climbing ladders as volunteers with Habitat for Humanity, a global nonprofit housing organization that helps homeowners build their own homes alongside volunteers.

Last week, Garth and Trisha worked alongside hundreds of volunteers—including former President Jimmy Carter and former First Lady Rosalynn Carter—during the 36th Jimmy & Rosalynn Carter Work Project, which constructed 21 houses in the Nashville area. Since beginning their work with Habitat for Humanity in 1984, just years after leaving the White House, President and Mrs. Carter have helped build, renovate and repair 4,331 homes in 14 countries alongside more than 103,000 volunteers.

“This is beautiful,” said Garth. “What these guys build are a lot more than homes. They build hope. They build love.”

An additional 12 new single-family homes and 26 new townhomes will be constructed by 2021 with support of funding raised for the project. In total, funds raised through the 2019 Carter Work Project will serve 59 Nashville families.

Garth and Trisha first volunteered together with Habitat for Humanity in 2007 in New Orleans to help build post-Katrina homes.
