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, an oversized four-car garage, three HVAC systems with six zones, and beautifully manicured, private grounds.
