The little yellow house officially known as the Brandywine Consignment Shop in Downingtown has long had a big impact on the health of Chester County, and a Wednesday groundbreaking ceremony will help the 14-year-old shopping destination grow its small physical space to match its big reputation.

At 1:30 p.m. today volunteers broke ground on the five-month construction effort to double the shop’s floor space.

The Brandywine Consignment Shop has already invested half a million dollars into the Brandywine Center in Coatesville for primary health care services, prenatal and dental care, a pharmacy, and behavioral health services for residents throughout the county and beyond via ChesPenn Health Services and Child Guidance Resource Centers, as well as for its 24 affordable senior living apartments.

The Yellow Houses’s current $50,000 annual contribution could at least double to $100,000 after the expansion, according to a 10-year business plan developed by SCORE volunteer and charitable BHS Transitional Corp. Board Chairman Jim Friedman.

Architetra Co-Owner Todd Kentzel of Paoli designed the plans, Speaker Construction of West Chester will build the addition and more than 100 community volunteers will continue to operate the shop.
