Luxury truly lives in the details of this exceptional custom home, tucked at the back of an exclusive gated community in Flower Mound and zoned to highly sought-after Argyle ISD. Situated on a one-acre lot, this estate was designed for everyday comfort and effortless entertaining. The open-concept kitchen and living area showcase soaring beamed ceilings and top-tier appliances including a Sub-Zero refrigerator, Wolf range, double ovens, and refrigerated drawers. A fully equipped prep kitchen with a second dishwasher, wine and a full size beverage and wine fridge, ice maker, and walk-in pantry keeps hosting seamless and organized. The primary suite feels like a private retreat with two walk-in closets, a personal gym with Tonal system, sauna, coffee bar with mini fridge, spa-inspired shower, and even an outdoor shower! Most of the living space is thoughtfully located on the first floor, including four spacious ensuite bedrooms with walk-in closets, a private office with its own bath that could serve as a sixth bedroom, and a den with built-in desks. Upstairs offers flexibility with a game room (complete with reading nook and murphy bed), kitchenette, full bath, and guest suite ideal for entertaining or multigenerational living. Outdoor spaces were equally prioritized with a front courtyard featuring a fireplace, dining space and water feature, then the backyard oasis complete with pool, spa, firepit, outdoor fireplace, and full outdoor kitchen with built-in grill and fridge. Additional highlights include a 4-car garage with HVAC, dog wash station and two EV chargers, whole-home Halo water filtration, smart home features, integrated SONOS system with TVs included, level 4 tile roof, two whole-home generators, and a pool with in-floor cleaning system and hard cover.
