A vacant, deteriorated shell transformed into a 5,000 sq ft single-family townhouse — and a piece of Harlem real estate history. Bill rebuilt the property from the ground up, preserving the original facade while completely reimagining the interior. The project set a record for Harlem townhouse prices north of 125th Street upon its sale in 2003, delivering a 30% return for investors in a single year. The buyer resold it seven years later for almost triple the purchase price.
