Welcome to This Stunning Postmodern Masterpiece in Half Hollow Hills SD.
Impeccably improved and maintained by its original owner since 2001, this exceptional 5-bedroom, single-family residence offers the perfect blend of grand design, modern luxury, and total privacy. Set on a generous lot with a sweeping driveway, the home makes a statement from the moment you arrive — and delivers on every promise once inside.
A commanding two-story foyer and elegant sweeping staircase set the tone, flowing into expansive formal living and dining rooms. The heart of the home is a chef's kitchen equipped with premium Sub-Zero appliances, a breakfast bar, and a casual dining area that opens seamlessly into a warm, inviting den — all overlooking a spectacular backyard retreat complete with a large patio, a fully equipped outdoor kitchen, and a sparkling in-ground pool.
A versatile first-floor bedroom suite with a private bath and separate entrance offers endless flexibility — whether as a home office, nanny suite, or in-law accommodations. A dedicated pantry, laundry room, and an oversized 3-car garage round out the main level.
Upstairs, the primary suite is a true sanctuary, featuring dual walk-in closets and a spacious ensuite bath. Three additional generously sized bedrooms, a large shared bath, and a bonus space provide room for everyone and everything.
The fully finished basement with high ceilings effectively doubles the home's living space — ready to become a home theater, gym, playroom, or whatever suits your lifestyle. Basement is accessible by legal outside entrance.
Located in the highly coveted Half Hollow Hills School District, this one-owner gem offers the privacy, space, and luxury today's discerning buyer demands.
