Set on 2.3 fully fenced, usable acres in private Southlake cul-de-sac, this rare modern estate delivers an almost impossible combination: land, Carroll ISD open enrollment, a newer custom home, no HOA, and resort-style amenities at a value well below replacement cost. Built in 2016, the single-story main residence was thoughtfully designed for modern living and effortless entertaining. A light-filled, open floor plan flows seamlessly to the outdoors through massive panoramic sliding doors, opening to a covered patio with new motorized screens, creating true year-round indoor-outdoor living. The main home features three oversized, master-sized bedrooms, each with en-suite baths, a dedicated office, and a generous bonus space that can easily convert to additional bedrooms, media, or flex living, offering long-term adaptability without compromise. Additional highlights in the main home include, foam insulation, a full house water filtration system, EV charger, stack dishwasher, separate laundry room in primary bedroom, and thermostats in each bedroom for added convenience. Outdoors, the property truly distinguishes itself. The grounds are fully utilized and designed for lifestyle, featuring mature hardwood trees, a turf soccer field, brand-new fenced pickleball court, expansive play areas, a resort-style pool and spa, and a storage barn for recreational gear and equipment, all within a setting that feels private, peaceful, and rare for Southlake. With no HOA, sidewalks leading to nearby walking trails, and a quiet cul-de-sac location, the setting offers both freedom and refinement. As a bonus, the estate includes additional independent living quarters, ideal for multi-generational living, guests, or future flexibility without detracting from the primary home’s elegance and cohesion.
