Sited on 1.39-acres connected via private gate to the prestigious St. Mark's School, sits 6300 Brookshire Drive, a timeless estate of uncompromising craftsmanship. From the winding, tree-filled approach, this commanding 13,457 square foot home evokes a true sense of arrival and prominence. Custom built by the sole owners with no expense spared, the home boasts rich materials like mahogany hardwoods, hand-selected stone, and reclaimed wood accent details. An entertainer's dream, the home has lovely formal spaces that flow with ease and grace and include butler's pantry, catering kitchen and a well-equipped serving bar. At the heart of the home, and the center of everyday living, is a comfortable eat-in kitchen that flows into a family room and adjacent media room - perfect for sporting events or movie nights. A first-floor guest suite with full bath and kitchenette offers ideal accommodations. The expansive primary suite above has an exercise room, private balcony with hot tub and flows through a wet bar into an exceptional living room with fireplace. Six additional bedrooms, including one separated for an au pair, span the second level, as well as a large study, game area, and ample storage. The grounds are private and serene, encased in mature trees, lush garden spaces, and stone walking paths. The covered outdoor loggia features a fireplace with a hanging firebox inspired by Marjorie Merriweather Post's Adirondack retreat and overlooks the pool and spa. There is a separate cabana large enough to use as a golf simulator with access to an outdoor pool bath. Outside of the five garage bays, a large motor court doubles as a hard surface play area. Through the back gate, the St. Mark's campus extends your domain, offering green space, security, and world-class amenities steps from your door. With its rare combination of stature, scale, and location, this estate offers a once-in-a-generation opportunity to create your legacy in the heart of Preston Hollow.
