Quintessential Mid-Century Modern on the Historic Grounds of Valley Brook Farm Set on the historic grounds of “Valley Brook Farm,” the storied Howard and Pew family estate, this quintessential modern home offers a rare combination of architectural pedigree, privacy, and natural beauty rarely found today in Newtown Square. Designed by architect McElroy and built in 1967, the home has been lovingly maintained by its current owners and stands as a striking example of mid-century design at its best. The approach is part of the property’s story. Enter through the estate’s original stone columns — once the entrance to Valley Brook Farm - with a mowed clearing on your left that could easily be restored to lawn for family games and entertaining. The drive then crosses a stone bridge over a babbling stream before reaching the home, where a turnaround and ample parking sit just to the right, with the home to the left; enter via the rear steps. Inside, the main level is anchored by a soaring, light-filled living space with cathedral ceilings and walls of floor-to-ceiling glass that frame views of the stone bridge and stream below. At its heart is the home’s original copper fireplace, a striking focal point that flows seamlessly into an open dining area and adjoining den - all wrapped in the same dramatic views. Large kichen with a generous island and a walk-in pantry. Hardwood floors run throughout the main living level, and a wide deck spans the front of the home, offering direct access from the primary bedroom, living room, dining room, and den - ideal for morning coffee or evening entertaining under the trees. The main-floor primary suite is a true retreat, with a generously sized bedroom, ample closet space, and wooded views visible right from bed. Three additional bedrooms and two full baths - including one bedroom with a private ensuite — are located on the lower level, along with a second living room and a large hall bath, offering flexible space for family, guests, or a home office. In all, the home offers 4 bedrooms and 3 full baths. Perhaps most remarkable is the setting itself: the land behind the home, extending to Goshen Road, is owned by Radnor Township and will remain undeveloped, permanently preserving the property’s exceptional privacy and serenity. Both the rear sitting area and main entry offer the opportunity to add a stone patio for even more outdoor living space. Radnor school district, and on the border of Newtown Square and Bryn Mawr. This is a rare opportunity to own a piece of architectural and local history - a private, sun-filled retreat. Listing will be Active on Friday August 21st.
