The manor house at Rapidan Farms was designed by noted German architect Caesar Pinnau and supervised by Milton Grigg, a Jeffersonian restoration and rehabilitation expert. The residence is entirely brick with a slate roof and the floors in the entry and living room are Georgian marble. A wonderful brick courtyard is created at the front of the house with a 3-car garage on the left, the main house in front, and a guest wing on the right. The first floor contains a gracious entry hall, powder room, living room, dining room, study with fireplace, and a kitchen. The second floor contains two bedrooms each with a bath and a grand master suite with a sitting room and spacious bath/dressing area. A covered arcade connects the four bedroom, two bath cottage with living room and kitchen on the other side of the residence. A complete basement houses a wine cellar, storeroom, laundry room, mechanical room, and additional storage rooms. The property has propane heat and central air conditioning.
