About this home

Rockland Delaware Historic Home Nestled on 2.2 acres and surrounded by the Brandywine Creek State Park. The original home was built in 1790 and added to in 1840. The original spring house still exists along with the original stone fence. In 1929 the home, owned by Henry DuPont and used as a tenant house for his grounds keeper, was renovated. After being vacant for many years, the current owner has restored the home to its modern glory. The home has a septic system for a 4 bedroom home. The current layout of the home features 2 bedrooms and 1.5 bathrooms. There is a possibility that a multi story 15' x 30' addition could be added to the rear of the home and due to the historic nature of the home there are some restrictions and approvals required BUT there is also the possibility of a tax credit. There is also the possibility to have a garage and/or an additional driveway at the rear of the home beyond the historic stone fence. The current driveway is shared with the neighbor, please be courteous as to not block the neighbor.
