Sprawling, classic colonial with resort-like grounds/amenities that's been totally reimagined on one of Gladwyne's premiere cul de sacs. Current owners have made significant infrastructure/systems and technology investment to what is an incredibly unique property that has been thoughtfully re-built with the most exacting details. Open, 'new house' floorplan ideal for both entertaining and comfortable, modern family living. Dramatic two-story entry and center hall. Formal living room with gas fireplace. 'Great room' anchored by lavish custom kitchen with natural stone counters, Wolf/Subzero appliances, oversized double islands, two dishwashers/sinks, pantry, and separate breakfast/morning area with built in office. Kitchen opens to both a stylish family room with vaulted ceiling, gas fireplace and custom built-ins, and formal dining room that comfortably seats ten. These spaces are oriented entirely to the Trex deck, tiered rear yard, and one-of-a kind infinity pool, creating rare indoor/outdoor entertaining opportunities and providing both sunny and shaded outdoor living spaces with retractable, remote-operated 'phantom' screens. Attached, 2-car garage with Tesla chargers, fully outfit mudroom and new laundry room addition complete the main living level. 2nd floor: primary bedroom with his/hers walk-in closets, and luxe, marble clad en-suite bath with separate vanities and steam shower with frameless glass enclosure. Three additional, well-proportioned bedrooms, all fitted with custom closet organizers, and classic, marble-clad hall bath complete the 2nd floor. Third floor 5th bedroom/guest suite with built-ins and newly renovated bath. Over-the-top finished, walk-out lower level features a pro-quality gym with ERV system (fresh air intake), additional guest suite (6th bedroom) with new full bath, game/playroom, family room, dedicated laundry for pool, and second full bath to service swimming pool exclusively. Sliding doors out to shaded bluestone patio, and steps down to exceptional, new infinity pool with integrated spa, waterfall-edge, fire features, tanning ledges, resort-size travertine pool deck w/ multiple seating areas, fire pit, separate shaded pool pavilion with retractable screens, mature landscaping, retaining walls, and tiered flat grassy spaces. Whole house generator, irrigation system, and extensive landscape lighting. House is served by public sewer, and is very efficient with extremely low utility bills. 12-zone Sonos system. HVAC system with top-of-the-line air 'scrubbers' (anti-bactieral, anti-viral, etc...). An extraordinary property that needs to be experienced in-person to fully appreciate. **All dimensions/square footage figures should be independently verified.**
