Listed by BHHS Fox & Roach-West Chester
Welcome to this 3.73-Acre Sanctuary in the Heart of the Main Line In an era where the Great Estates of Lower Merion are being subdivided and condensed, Hearthstone stands as a defiant outlier. Spanning nearly four lush, level acres in the coveted Indian Creek corridor, this is not just a residence—it is a private ecosystem. It offers a scale of "Land and Liberty" that is virtually extinct in Wynnewood, providing the next steward with a canvas of almost 4 acres to create a generational masterpiece. Commissioned in 1928 by William P. Simpson, President of the Eddystone Manufacturing Company, the estate was born of a singular vision. Simpson personally designed the home to anchor a life of industrial-age grandeur. Known historically as "Hearthstone," the residence served as a beacon of the 1930s social circuit, positioned steps from the Indian Creek Nature Preserve. Today, the house retains its original 13,000+ square feet of grand-scale architecture. With its stone façade, two-level elevator, and soaring enclosed porches overlooking the gardens, the bones of the estate offer a structural integrity and "volume" that modern construction cannot replicate. This home is truly a Lifestyle Without Compromise: While most luxury homes in the district offer proximity or privacy, Hearthstone provides both. The Main Residence: 9,800+ SF of finished living space, with an additional 3500+ SF unfinished, featuring 10 bedrooms and grand entertaining halls awaiting a high-design transformation. The Orchard & Grounds comprise of a flat, oversized yard—rare for the topography of the area—complete with a private fruit orchard and specimen gardens. The Aquatic Pavilion is a classic 10-foot deep in-ground pool anchored by an oversized patio and a dedicated Bathhouse with room for improving the full amenities such as the individual shower facilities and wet bar designed for grand-scale summer galas and garden weddings. The Infrastructure is already equipped with a full-house generator and 5-zoned HVAC, the estate offers a sophisticated head-start on a modern restoration. Hearthstone offers a strategic advantage for the modern family. Situated in the heart of the award-winning Lower Merion School District, it sits at the epicenter of the nation’s most elite private academies, including Baldwin, Haverford, Shipley, and Agnes Irwin. With the Merion Cricket Club and world-class golf just minutes away, the estate offers a seamless blend of secluded sanctuary and social connectivity. This is not Ia finished product; rather it is an opportunity to be the next great steward of a Wynnewood landmark, minutes to the city in an award-winning school district. For the buyer who understands that land is the ultimate luxury, Hearthstone represents a "buy-and-renovate" scenario where the finished value will be personalized to what future buyers want in a luxury home as well as command the top of the Main Line market. Hearthstone is more than a home; it is a 3.73-acre legacy!
