Together, the Knowltons have invested over five years into building this remarkable 40,000-square-foot estate, merging modern technology with classical design elements. Their dedication to creating a home that is both sustainable and luxurious reflects their vision for a lasting legacy.
Exterior and Grounds
Set on several acres of meticulously landscaped grounds, the mansion features beautiful outdoor spaces, perfect for grand entertaining or tranquil private moments. A reflecting pool at the center of the estate adds a serene touch to the property’s extensive gardens. The landscaping complements the home’s classical design, blending outdoor beauty with sophisticated architecture.
The home’s exterior design mirrors timeless European influences, with a facade reminiscent of historical castles. Despite its grandeur, the home maintains modern appeal through innovative construction methods. The gated property offers a unique opportunity for privacy while still being located conveniently close to major cities such as New York and Washington, D.C.
Interior Features
Upon entering the estate, visitors are greeted by dual floating staircases that create a dramatic focal point in the grand entrance. The living room and dining room embody sophistication and elegance, featuring intricate woodwork, custom lighting, and expansive windows that flood the space with natural light. Designed for a chef, the gourmet kitchen comes complete with state-of-the-art appliances, large countertops, and ample cabinetry, making it ideal for both everyday cooking and formal entertaining.
The mansion also features a range of luxurious amenities, from a private theater and tavern-style pub to a wine cellar and home gym complete with a sauna. One of the most striking additions is the automobile elevator, which transports cars to a specially designed room with a unique ventilation system—perfect for car collectors.
Modern Innovation and Classic Luxury
The home incorporates cutting-edge technology, including a geothermal HVAC system and radiant heating throughout, ensuring that the estate is energy-efficient and comfortable year-round. These modern conveniences seamlessly blend with the home’s classic design elements, creating a unique combination of old-world charm and contemporary comfort.
The master suite, situated in a separate wing of the mansion, offers an opulent retreat for the owners. This luxurious suite includes a private sitting area, dual walk-in closets, and a spa-inspired bathroom. One of the more unique features is a tube elevator that connects the master suite directly to the home gym, ensuring ease of movement within the sprawling property. The master bathroom is a true spa-like experience, with a steam shower, soaking tub, and custom vanities that exude sophistication.
In addition to the master suite, the home includes six additional spacious bedrooms, each designed with en-suite bathrooms and walk-in closets. Each room has been curated with bespoke lighting and detailed finishes that make the estate one-of-a-kind.
Recreational Spaces and Additional Amenities
The lower level of the mansion is designed for recreation and entertainment. It includes an expansive space with a custom-made pool table, lounge areas, and even a sports court perfect for indoor activities like pickleball. The home theater, designed to mirror a cinema experience, offers plush seating and state-of-the-art projection equipment for private screenings. The pub-style room and wine cellar provide an ideal space for hosting gatherings, blending relaxation with luxury.
Outdoors, the property is equally suited for leisure and entertainment. The covered patio is the perfect spot for enjoying the outdoors while remaining sheltered from the elements. Whether hosting a large gathering or enjoying a quiet family dinner, the outdoor spaces have been designed to be both practical and beautiful. The landscaped grounds feature multiple seating areas and garden paths, making the property a serene retreat for its next owner.
Price Reductions and Auction Details
First listed in November 2022 for $24.95 million, the mansion has undergone several price adjustments. The home was reduced to $19.75 million in June 2023, and most recently, it has been listed at $10 million. This significant reduction reflects the Knowltons’ desire to sell the property quickly, as the luxury real estate market has posed challenges. Despite its extensive features, the mansion has been slow to find a buyer, prompting the family to move forward with a luxury auction.
The estate is now being auctioned by Paramount Realty USA, with bidding open until October 9, 2024.
