About this home

Beyond excellence in craftsmanship and exuding rare elegance of proud owners, this stunning estate is located in the award-winning 2,900-acre master-planned and mixed-use community of Castle Hills. Luxury and customization are standard in this neighborhood. Follow along as we hit a few of the highlights of this luxury estate. Arrive to an immaculate well-kept landscaped front elevation with extended side driveway and warm stone covered front porch. Enter to soaring ceilings and a winding staircase with updated wrought iron balusters. Hand scraped hardwood floors are in most of the downstair areas. Plantation shutters, several built-ins, extensive millwork, prime views, and personalized amenities that rival other estates, you will love calling this home. The first-floor flows seamlessly between the front guest room suite with access to a front porch, enclosed study, formal dining room, and an open living area with a prominent stone fireplace highlighted by natural light that floods the area from a wall of windows. An eat-in kitchen is adorned with stainless steel appliances, refined finishes, and both an open island and breakfast nook. Also on the first floor is the laundry room complete with sink, ample storage and access to one of the primary closets. The spacious primary suite with oversized sitting room with French doors and retractable screen, opens to the deck and hot tub. The primary bath was completely remodeled and there are two His and Hers closets. Upstairs are three spacious bedrooms, game room with a wet bar and access to balcony with great views, media room, and a bonus room with a view and access to walk out storage in the attic. So many upgrades and so much attention to all the details. The backyard is a dream with outdoor kitchen; extended covered patio, a deck and hot tub, and a media cabana complete with retractable screens and views of hole #12 at The Lakes of Castles Hills.
