This French château-inspired mansion, owned by Dr. Inder Chawla, spans over 55,000 square feet, making it the largest home in Maryland. As a lead interior designer, I have worked on some stunning properties across the country, but few rival the grandeur of this estate.
Today, we take a detailed look at this architectural masterpiece, breaking down its interior design, unique features, and the secrets behind creating spaces that exude elegance and functionality.
A Foyer Fit for Royalty
Stepping inside 10423 Willowbrook Drive, you are greeted by an entrance that belongs in a European palace. The massive double doors, framed by towering Corinthian columns, open into a space that immediately establishes the home’s grandeur. The arched ceilings, chandelier lighting, and intricate floor patterns create a sense of timeless luxury.
I remember walking into a celebrity’s home in Beverly Hills and thinking, “Okay, this is over the top.” But that was nothing compared to this. The sheer scale of the foyer, with its dramatic staircase and marble-clad walls, is unlike anything you’ll find in most luxury homes.
A Staircase That Demands Attention
What’s a mansion without a grand staircase? This home features a sweeping dual staircase with ornate railings, perfectly positioned to lead your eyes upward to the massive arched windows on the second level. Natural light floods the space, bouncing off the polished stone floors, enhancing the air of opulence.
Lounge Areas That Redefine Luxury
A house of this size doesn’t have one living room. It has several, each designed to blend elegance with comfort. High ceilings, intricate moldings, and statement fireplaces give the main lounge a sophisticated ambiance. Plush furnishings in neutral tones create a sense of balance, ensuring the space doesn’t feel overwhelming.
Dining in Style
The formal dining room is built for hosting grand dinner parties. A long banquet table, gilded chandeliers, and ornate wall paneling transport guests to another era. The casual dining area, located off the chef’s kitchen, offers a more relaxed setting, featuring warm wood tones and oversized windows that overlook the gardens.
Master Bedroom: A Sanctuary of Comfort
If there’s one thing I’ve learned designing high-end homes, it’s that the master suite must be a personal sanctuary. This one doesn’t disappoint. Featuring a spacious sitting area, private balcony access, and a custom-designed fireplace, the master suite blends traditional elegance with modern luxury.
Bathrooms Worthy of a Five-Star Hotel
The ensuite bathroom is an architectural marvel, boasting floor-to-ceiling marble, a deep soaking tub, and gold-accented fixtures. The attention to detail in this space rivals that of high-end European spas.
A Home Theater Experience Like No Other
A house of this magnitude wouldn’t be complete without an ultra-luxurious home theater. Think plush reclining seats, soundproof walls, and a massive projector screen. The design ensures an immersive cinematic experience, making movie nights something special.
Billiards, Bar, and Beyond
A dedicated game room features a billiards table, a fully stocked bar, and custom-built lounge seating—perfect for entertaining guests in a relaxed yet stylish setting.
A Private Spa Experience
One of the most enviable features of this home is the fully-equipped indoor spa, designed to rival the world’s best wellness retreats. It includes a massage room, sauna, and a steam shower, ensuring complete relaxation without ever leaving home.
The Home Gym: Fitness Meets Luxury
The home gym is outfitted with top-of-the-line equipment and large floor-to-ceiling mirrors, making workouts feel like a session at an exclusive private fitness club.
French-Inspired Courtyards and Gardens
The manicured gardens surrounding the property are designed to complement the château-style architecture. Tiered terraces, stone pathways, and sculpted hedges create a formal yet inviting atmosphere.
Infinity Pool with Breathtaking Views
The infinity pool is a true masterpiece. Its sleek black design and reflective surface create a stunning contrast against the estate’s light-colored stone terraces.
