Castle-Inspired Maryland Mansion With Hidden Doors Finds Buyer in Record Time
May 7, 2025 — Luxury Real Estate Desk —
A sprawling Tudor-style estate in Potomac, Maryland, inspired by fairy-tale castles and loaded with luxurious amenities, has sold privately for $4.595 million — without ever being listed on the MLS.
The home, nestled on 10 secluded acres, features secret staircases, concealed doors, and a blend of whimsical design with modern convenience. It also boasts an indoor basketball court, a gym and sauna, a five-car garage, and lush views of forest conservation land.
“It’s a true private estate experience,” said Lee Arrowood of Compass, who handled the off-market deal, set to close on May 15.
Custom-built in 2008 by noted builder Brendan O’Neill, the 16,718-square-foot mansion includes six bedrooms, eight full bathrooms, and one half bath. The exterior showcases an impressive stone and limestone façade, while the interior highlights vaulted ceilings, custom millwork, and 14-foot-high ceilings in the grand entryway.
Arrowood describes the interior as a blend of old-world charm and elite craftsmanship. Jerusalem limestone floors, a walnut staircase, and floor-to-ceiling Palladian windows in the great room enhance the home’s regal presence.
Secret Passages and Lavish Spaces
A unique hidden staircase tucked behind a mirror leads to the primary suite via a movable bookcase. This suite features dual walk-in closets, a private sitting room, a balcony, and a fireplace. The second floor hosts a children’s study and additional bedrooms.
On the main floor, highlights include a medieval-style dining room, two home offices (one with cathedral ceilings), and a chef’s kitchen with top-tier appliances, a butler’s pantry, and a cozy fireplace nook.
The walkout lower level impresses with its indoor sports court, gym, sauna, and entertainment spaces. Outdoors, the property includes multiple patios, a circular auto court, and manicured landscapes.
Adding to the storybook ambiance, the seller even allowed a neighbor’s sheep to graze on part of the land.
Community and Lifestyle
“Red Barn Lane is one of Potomac’s most picturesque roads,” Arrowood added, noting the neighborhood’s preserved rural charm. Despite the estate’s secluded feel, Potomac Village is just minutes away, offering shops, restaurants, and cultural venues like the Glenstone Museum.
Washington, D.C. is a 30–45-minute drive, making it ideal for luxury buyers seeking tranquility with city access.
