Step back in time and own a remarkable piece of Delaware history with the Dilworth House, believed to be one of the earliest homes built in the state. Set on 12.25 scenic acres backing to the Augustine Wildlife Preserve, this extraordinary property offers a rare blend of historic significance, timeless character, and endless potential. The Dilworth House is a true architectural treasure, showcasing exceptional early masonry craftsmanship. Distinctive glazed brick “diapering” in diagonal patterns decorates the gable ends, while stepped belt courses and detailed framework further highlight the home’s historic charm. Inside, original character abounds with exposed beams, impressive brick fireplaces, and period details that reflect the home’s early construction, when it was built in two sections and heated by a single chimney. This three-story residence features 6 bedrooms, 3 full bathrooms, and 2 half bathrooms, with a finished third-floor attic offering additional living space. The partial basement remains unfinished. While updates have been made over time including the plumbing and electrical, much of the home remains in its original condition and will require major restoration, . Beyond the home, the property is well suited for those interested in farming, mechanical work, or automotive pursuits. Existing improvements include a silo, milk house, dairy barn, cow shed, and storage shed. The barn has been converted into a workshop but could easily be adapted for a variety of uses. The expansive acreage may also offer subdivision potential, adding even more value and opportunity. This is a rare chance to own an iconic and historically significant property in a breathtaking setting. Schedule your private tour today.
