Affordable housing remains one of the most pressing issues facing families across Gwinnett County, but a local organization is out to prove that lowering the cost of mortgage payments is only half the battle. Gwinnett Habitat for Humanity is showcasing how intentional, energy-efficient home design can significantly cut down on monthly utility bills, keeping long-term living costs manageable for low-to-moderate-income families. The organization's brand-new sustainable housing development is officially opening its doors to the Lilburn community this week, offering a blueprint for future regional growth.
