Listed by Triamond Realty
A rare opportunity in one of Radnor Township’s most desirable locations, this beautifully updated greystone residence offers the privacy, setting, and sophisticated living today’s Main Line buyer is seeking. Tucked away at the end of a quiet cul-de-sac and adjacent to the picturesque grounds of Overbrook Golf Club, the property feels remarkably secluded while remaining convenient to everything that makes Radnor so coveted. Step inside and discover a home that is as impressive in scale as it is in style. Newly installed flooring flows throughout the residence, complementing a thoughtfully renovated and exceptionally flexible floor plan. At the heart of the home is a gourmet island kitchen designed for both everyday living and effortless entertaining. A gracious formal living room features a newly renovated fireplace surround, while the inviting dining room with bar creates an elegant setting for intimate dinners and larger gatherings. Just beyond, a spectacular Great Room addition opens across the rear of the home, with soaring vaulted ceilings and beautiful views of the private grounds. This light-filled space creates a seamless connection between indoor and outdoor living—and leads to a backyard that feels like a private resort. Surrounded by mature privacy trees, perennial gardens, flowering shrubs, and a wooded landscape bordering Overbrook Golf Club, the outdoor setting is truly exceptional. Expansive patios provide multiple areas for dining, entertaining, and relaxing around the in-ground swimming pool and spa. Whether hosting a summer gathering or enjoying a quiet afternoon by the pool, the setting offers a level of privacy that is increasingly difficult to find in Radnor Township. The upper levels provide equally impressive accommodations. The luxurious Primary Suite features generous walk-in closets and a beautifully appointed spa bath. An additional bedroom and full hall bath complete this level. Just six steps above is an expansive second suite with an en-suite bath, abundant closet space, and substantial attic storage. Its generous proportions offer tremendous flexibility and could easily be reconfigured to create two separate bedrooms. The lower level adds yet another comfortable living area, with a mudroom conveniently accessed from the two-car garage, a second Family Room with fireplace, and a powder room. Also an unfinished basement provides lots of storage space. Designed to evolve with its next owner, the home’s flexible floor plan offers the potential for four or five bedrooms, making it equally suited to sophisticated entertaining, working from home, extended family, or changing needs over time. A whole-house generator provides additional comfort and peace of mind year-round. Private. Spacious. Beautifully updated. And positioned at the end of a cul-de-sac in an exceptional Radnor Township setting. Opportunities combining this degree of privacy, outdoor living, flexibility, and location are exceedingly rare on the Main Line.
