Property Description

Elegant gated estate in sought-after Gladwyne, masterfully designed by renowned architects Peter Batchler alongside architectural designer, Christina Waters, offering exceptional craftsmanship, scale, and versatility. A grand two-story marble foyer with a sweeping curved staircase makes a striking first impression and opens to the spectacular great room, highlighted by soaring ceilings, a Heat & Glo gas fireplace, and custom built-ins with a lighted display and media center. This impressive space flows seamlessly into the chef's kitchen, featuring rich custom cabinetry, an oversized center island with seating, and top-of-the-line stainless steel appliances, including a Thermador cooktop, a new refrigerator, double dishwashers, wall ovens, and a Sub-Zero wine and beverage refrigerator. A sun-drenched breakfast area with built-in bench seating overlooks the serene, private grounds. The stunning sunroom serves as a true indoor-outdoor retreat, complete with multiple seating areas, a dining space, hurricane-rated windows, and a full indoor grilling kitchen perfect for year-round entertaining, all with picturesque views of the lush backyard. The formal dining room, adorned with elegant crown molding, is ideal for hosting and is complemented by a well-appointed butler's pantry. Additional main level highlights include a richly detailed home office with custom built-ins, two powder rooms, multiple pantry closets, and a spacious, well-equipped laundry room. The luxurious first-floor primary suite offers a private sanctuary, complete with a Heat & Glo gas fireplace, custom built-ins, and an expansive, professionally outfitted walk-in closet. The spa-inspired primary bath features dual vanities, separate water closets, a soaking tub, and an oversized glass-enclosed shower. The second level offers two generously sized bedroom suites with ensuite baths, along with two additional bedrooms connected by a Jack-and-Jill bathroom. A standout feature is the fully self-contained one-bedroom apartment with both private exterior access and interior connectivity, ideal for an au pair, in-law suite, or extended guests, complete with a living area, full kitchen, separate bedroom, full bath, and its own laundry. The finished walkout lower level provides exceptional additional living space, including a large media and recreation room, fitness area, full bathroom, a private office with exterior access, and abundant storage. Additional features include an elevator servicing all levels, a full-house generator and an oversized four-car garage, three HVAC systems with six zones, and beautifully manicured, private grounds. Ideally located just minutes from the Village of Gladwyne with convenient access to Center City Philadelphia, major roadways, premier shopping and dining, and situated within the highly acclaimed Lower Merion School District, this extraordinary estate offers refined Main Line living at its finest.
