Property size: Twenty-acre waterfront estate features a 16,621-square-foot stone house that includes six bedrooms, eight full and three half bathrooms, a guest house, carriage house and a nine-car garage

Unique features: Downton Abbey, eat your heart out. This gated waterfront estate isn’t merely a house. It’s practically its own French village, complete with a chicken coop. The mansard roof, formal gardens, wine cellar, floor-to-ceiling built-in bookshelves, paved motor court and toile window hangings may put the new owners in mind of the kinds of country houses that previously hosted minor aristocracy.

The interior of the main house features a two-story foyer with limestone and marble inlays. The formal dining room boasts some of the most elaborate ceiling moldings in recent memory while the two-story great room features a fireplace mantel carved in the 18th century from French limestone.

Other standout interior features include a stone wine cellar and tasting room, an art studio, a media room and a home gym with full bath and sauna.

There’s a huge kitchen indoors with a double island and an outdoor kitchen for warm-weather entertaining. Even the kitchen in the guest house features coveted Viking appliances.

There’s an outdoor swimming pool, and a charming, tucked-away little fountain, and a reflecting pool and iron gates and low brick walls perfect for sitting, and terraced steps. And — should visitors get lost while rambling those 20 acres and drinking in views of the Severn River — street signs providing directions back to the main house, guest house and pool deck.

And did we forget to mention the estate’s 900-foot shoreline, it’s 350-foot pier, six deep-water boat slips and two boat lifts?
