Welcome to The Hartz Estate, a truly one-of-a-kind residence steeped in Danville’s early history. Once home to John Hartz, one of the town’s pioneering founders, this stately Colonial-style home is a rare blend of heritage, elegance and potential—set on an ultra-private, flat 1.58-acre lot just minutes from downtown Danville. Framed by a gated circular driveway and lush landscaping, the estate exudes timeless character. Inside, the main residence offers formal living, dining, and family rooms showcasing exquisite millwork and traditional craftsmanship. The spacious kitchen at the rear of the home offers serene views of the tranquil grounds and incredible expansion potential for a luxury kitchen remodel or great room concept. Upstairs, two different staircases lead to five bedrooms, including a versatile room currently used as a home office. Beyond the main home, the estate features an impressive suite of auxiliary structures: a one-bedroom ADU above the garage, a large pool house with a second kitchen, ideal for entertaining, and a 5,000+ bottle wine cellar. The large, flat lot presents a rare opportunity for subdivision or a complete reimagination into a contemporary family compound.
