1421 Red Oak Circle Set on a peaceful one-acre lot in Willow Brook Park Estates, this thoughtfully designed custom home blends sophistication with everyday comfort. A circle drive with separate parking for the in-law suite, mature trees, and no rear neighbors enhance privacy, while irrigated flowerpots and natural landscaping create a serene retreat. Inside, the flexible layout highlights quality finishes throughout. A private in-law suite (or casita) with its own entrance includes a living room, kitchen, bedroom, bath, laundry, 32-inch doorways, and a roll-in shower, ideal for guests or multigenerational living. The main residence features cathedral ceilings, luxury vinyl plank flooring, granite surfaces, barn doors, and crown molding. The kitchen showcases custom cabinetry, quartz countertops, farm sink, champagne fixtures, dual pantries, and an auto-sensing vent hood, all opening to a living area with vaulted beam ceilings and a glass rock tile fireplace. A dedicated office with french-doors adds flexible workspace. The primary suite offers a walk-in closet, built-in vanity, and oversized shower, while two bedrooms share a Jack-and-Jill bath. Upstairs, a game room with full bath, closet, and plumbing for a mini bar or kitchenette expands living space. An unfinished bonus room is perfect as a hobby room or teen retreat, while the third-floor observation deck delivers sweeping country views. Outdoor living includes a covered patio with built-in grill and ceiling fan, plus a tiered backyard framed by a retaining wall, ready for a pool. Car enthusiasts will love the oversized four-car garage with epoxy floors, 9-foot doors, built-ins, HVAC, and 220v power. Additional upgrades include two tankless water heaters, three HVAC units with five zones, soundproofing, exterior foam insulation, enhanced electrical and lighting, Christmas lighting switch, 16 LED up lights, sprinkler system front and back, and RJ45 direct-connect from the office to the telescope deck. A truly exceptional property!
