About This Home
Nestled on 2.56 acres in the coveted Eagle Ridge section of award-winning Avenel, this Potomac estate was originally designed by the renowned Natelli Homes for a prominent hotelier family who had a love of architecture, gardens, and car collecting. A graceful approach reveals the Georgian facade, evoking a sense of timeless sophistication through its symmetrical design, ivy-covered walls, and classic slate roof. Entering the grand center hall transports you to an era of old-world elegance. A bygone level of craftsmanship is evident throughout the 12,000-square-foot expanse. The arched Palladian window above is surrounded by intricate millwork, found throughout the home, and bathes the inlaid marble floors in natural sunlight.Embassy-sized formal living and dining rooms flank the reception hall, each with its intricate fireplace; two of seven in the home. The living room serves as a gateway to the conservatory with three walls of windows and soaring ceilings. A mahogany-paneled office/library with a roaring marble fireplace sits adjacent. The marble transverse gallery bisects the entire width of the main level and accesses the rear lawn via multiple sets of French doors. It connects formal and informal areas, which revolve around a modern and open kitchen. Its light cabinets and Carrara marble countertops contrast beautifully with the tile flooring. Within the kitchen is a breathtaking breakfast nook with a curved bay window that offers tranquil views of the English courtyard. The grand family room has a soaring honed limestone fireplace flanked by illuminated built-ins and herringbone floors. More French doors open to the rear lawn, affording true indoor/outdoor living. Opening directly onto the garden is the main-level primary suite. While the windows create a natural oasis, its location at the rear of the home provides both tranquility and privacy. The suite is complemented by a spacious, sumptuous bath clad in marble, several walk-in closets, and a fireplace. At the main stair landing is an upper-level gallery with cathedral ceilings and garden views. Four ample-sized bedrooms occupy respective corners of this level and are served by equally accommodating ensuite baths. On the walkout lower level, the open recreation room is paneled and boasts an intricately coffered ceiling while overlooking the second courtyard and pond. The stone floors are arranged in a striking Versailles pattern. The division into multiple areas centered around an inviting 2-sided fireplace creates distinct yet connected spaces. Bonus rooms offer ideal flexibility for the likes of a home gym or yoga studio. Outside, an artful combination of hardscaping and landscaping creates a private, wooded paradise. The sunken side patio is permeated only by the sounds of flowing water from the custom waterfall and pond. The hardscaping has been crafted to mirror the estate's overall symmetry. Outside the main gallery is a cozy seating area stepping up to a grassy lawn leading to a 40-foot heated swimming pool with an automatic cover. The pool is surrounded by flagstone and features a picturesque fountain. It's tucked away at the rear of the property with abundant trees that provide a natural canopy. An outdoor fireplace and BBQ area with a gas hookup are adjacent. The estate's piece de resistance are the facilities catering to the automobile enthusiast. 13 garage bays were built around the motor court, affording enclosed storage space for one's collectible vehicles, art collections, or a golf simulator. A climate-controlled workshop and a separate guest house above the garage bays, self-sufficient with a full kitchen, living area, two bedrooms, and a full bath. complete the offering. Eagle Ridge is the southernmost village of the Avenel golf community. It is the most accessible to DC and Northern Virginia. 9900 New London embodies the very ethos of Potomac while offering unparalleled proximity to Washington.
