Description

Located in nationally ranked Lovejoy ISD—one of the country’s highest-rated public school districts—this statement of modern luxury commands 2 private acres within an exclusive eight-home enclave in Lucas. The extraordinary 7,456-square-foot estate by Lone Star Legacy Homes welcomes you with soaring ceilings, hand-scraped white oak floors, artisan ironwork and designer lighting. Oversized windows and 10-foot multi-slide patio doors fill the great room with natural light and create a seamless connection to the outdoor living area. A showpiece chef’s kitchen delivers beauty and performance with a professional 48-inch gas range, dual ovens, double wall ovens, custom cabinetry and an oversized exotic-stone island. The primary suite is a private sanctuary with vaulted beamed ceilings, fireplace, beverage bar, bespoke wardrobe with marble accents and a foundation-integrated safe and storm room. Its resort-caliber bath features radiant-heated onyx and marble floors, a heated Kohler soaking tub and a sculptural marble shower with three rain heads and six body jets. Designed for elevated living and unforgettable entertaining, the home also offers an executive study, game room, dedicated theater with wet bar, first-floor gym or wellness studio and generous en-suite bedrooms. A fully independent detached casita—with kitchen, living room, bedroom and private laundry—provides exceptional accommodations for guests or multigenerational living. Outside, a sprawling travertine-covered terrace and complete outdoor kitchen create a year-round gathering space. A four-car garage with metallic epoxy floors and Level 2 EV outlet, oversized utility room, dedicated pet wash, four smart tankless water heaters, four 16-SEER HVAC systems, spray-foam insulation, built-in audio, whole-home central vacuum extending into the garage, fire sprinklers, fiber-ready connectivity and a 1-2-10 warranty complete an estate where dramatic design, thoughtful innovation and enduring construction converge.
