Private and sophisticated design define this beautiful Radnor home in the top-rated Radnor School District. Offering just under 5000 sq ft of indoor/outdoor living on a private acre lot, this 5 bedroom, 4.1 bath home is walkable to Radnor Elementary and High School and the Harford Dog Park. A carriage house from the early 1900’s, 185 Biddulph was reimagined and expanded by award-winning Gardner/Fox . As a premier design-build firm, Gardner/Fox’s meticulous craftsmanship seamlessly blends historic character with modern luxury. This renovation totally transformed and enlarged the home, introducing luxury finishes, almost 10 foot ceilings, and abundant windows framing views of the saltwater pool, and hot tub while creating an effortless flow that leads to multiple outdoor living spaces including screened porch and patios. Exceptional curb appeal meets extensive stone hardscaping and stately front door framed by handmade glass transoms. Inside you will find rich wood flooring, and deep-set windows offering gorgeous views from every room. The foyer leads to a Family Room with a wood-burning fireplace, opening to a spacious dining room with double French doors opening to a screened-in porch for a seamless entertaining flow. The David Stimmel-designed kitchen features custom Crystal cabinetry, tile backsplash, and a premium appliance suite: 6-burner Wolf range, 48” paneled Sub-Zero, Miele dishwasher, and GE Profile microwave. The center island includes a prep sink, Sub-Zero fridge drawers, and a butcher block inlay. An adjoining sun-drenched coffee nook/sitting room can easily accommodate a large dining table instead. From here, double French doors lead to a brick terrace with multiple seating and dining areas and a screened-in porch. This level also includes a sitting room with French doors to the pool, an office, a walk-in pantry, and a powder room. The Main-Level Primary Suite is a sanctuary added during the Gardner/Fox expansion, with high ceilings, gorgeous views, and French doors to a private balcony overlooking the grounds. The suite includes a walk-in closet outfitted by California Closets and a bathroom with double vanities, soaking tub, seamless glass shower, and private water closet. Off the Family Room, a staircase leads to the upper-level, also part of the Gardner/Fox renovation. At the top of the stairs is a spacious bonus room—a sun-drenched hangout space with overhead skylights and a built-in partition for versatile use, including as an additional bedroom. This floor includes three additional large bedrooms with custom built-ins—including a spacious Ensuite bedroom with its own bath—and a well-appointed hall bath with double vanities. The finished Ground Level is entirely above grade and provides a flexible living area updated with durable LVP flooring. Serving as the home’s original main entrance, this level features a large home gym (or 5th bedroom/playroom), a full bath with a seamless shower door, and a spacious laundry room with custom cabinetry. An entry with a built-in bench accesses the double-deep, 2-car garage with significant storage. The landscaped grounds offer abundant room to relax on the large grassy areas, deck, or patio. The exterior is a private oasis featuring a saltwater pool with a slide, electric safety cover, and a well tended garden with mature plantings. The Springhouse and under-house shed provide storage. This premier location is less than a mile from the Radnor Train Station with service to Philadelphia and NYC. Enjoy a unique lifestyle with walkability to the train, Radnor Elementary and High School, and the Harford dog park. Conveniently located near I-476, Route 30, and multiple corporate centers, with the dining and shopping of Wayne, Radnor, Villanova, and King of Prussia all close by. This home offers a sophisticated, move-in-ready lifestyle with a serene setting in an unbeatable Radnor location.
