About This Property
Step inside this 5,683 SF custom home in Estates of Pilot Knob, refreshed with fresh interior paint and window replacements, where hardwood floors, rich millwork and oversized windows pull the Texas woodland indoors. The vaulted family room, with exposed beams and a floor-to-ceiling fireplace, flows into a chef's kitchen with gas cooking, double ovens, walk-in pantry, butler's pantry and a grand island made for gathering. A formal dining room sets the stage for holiday feasts.
Rare TWO primary suites. Downstairs, the owner's retreat offers a sitting area, a flex room overlooking the backyard and a spa bath with garden tub, separate shower with body sprays and dual sinks. Upstairs, the second primary suite is ideal as a multi-generational suite, with private ensuite bath, walk-in closet and built-in desk. More ensuite bedrooms and full baths keep everyone comfortable.
Upstairs also hosts a spacious game room overlooking your backyard oasis and a dedicated media room for movie nights or gamedays, while a private office with built-ins handles Monday downstairs.
Step outside to your own resort: a pool and spa, covered patios and a wooded backyard with cul-de-sac privacy make every evening a getaway. NEW HVAC, NEW WATER HEATERS and NEW POOL EQUIPMENT mean the hard work is done. The 4-car garage and circular drive welcome guests with ease.
