Rooted in the traditions of Chester County’s early Quaker homesteads, this remarkable property dates to 1699 and is surrounded by hundreds of acres of conserved open space and walking trails. The main house has been thoughtfully reimagined to align with today’s aesthetics while preserving its historic integrity and exceptional craftsmanship. The owner, a highly respected designer, carefully leveraged the home’s orientation, long pastoral views, and abundant natural light to enhance the home’s original architectural character. Original floors were refinished rather than replaced, reinforcing authenticity. Select walls were removed on the main level to create a more open and gracious flow. What was once a smaller kitchen and dining area has been joined to form a generous family room anchored by a striking, impeccably designed kitchen. Similarly, the former parlor and music room are now combined to create a bright and expansive living and dining space. The family entry—finished with large-format Belgian bluestone floors and custom cabinetry—elegantly doubles as an independent dining room for hosting larger gatherings. The second floor features three ensuite bedrooms. The primary suite includes a walk-in closet, a custom bath with steam shower and thoughtfully selected fixtures. Two additional bedrooms, each with their own bath and reach-in closets, retain their original fireplaces for charm and historical resonance. A traditional staircase leads to the third level—left unrenovated because the space was not needed by the current owners. With high ceilings, existing plumbing, and an expansive open footprint, it presents an ideal opportunity for an additional two bedrooms and bathroom as well as an adjoining sitting room. Attached to the three-car garage is a two-story stone barn built in 1804. The first floor is finished as a guest or au pair suite and the second floor, accessed by a separate entrance, is ready to be finished as another living suite. Further down the private drive, at the entrance of the property, is a beautifully renovated post-Civil war Victorian house which features five bedrooms and two and half bathrooms. A renovation of the third floor would offer three more bedrooms and another bath. Directly across Grubbs Mills Rd is the 102-acre Kirkwood Preserve with magnificent walking trails and unparalleled views of the surrounding horse farms and open fields. Completing the property is an extraordinary stone bank barn—among Chester County’s most significant in both scale and architectural importance. The historic three level barn is ready for a creative renovation, while the finished lower level houses a renovated professional woodworking shop with heat and ac, studio lighting and 220V power. In every respect, this property has been transformed by its current stewards—artfully, carefully, and with deep reverence for both past and future. It is a rare and meaningful estate, and one the original owners would undoubtedly recognize with pride. Simply extraordinary.
