A rare opportunity to own one of Whitemarsh Township's most distinctive residences. Known as The Peace Barn, this extraordinary home began its story in 1814 as an addition to the historic Highlands barn and mansion. Today, it stands as a remarkable blend of preserved history and thoughtful modern living-a home unlike any other on coveted Sheaff Lane. Tucked away on over two impeccably maintained acres behind a tree-lined drive and surrounded by protected farmland, The Peace Barn offers a level of privacy and tranquility that is increasingly impossible to find. Just moments from Germantown Academy and major commuter routes, the property feels worlds away while remaining exceptionally convenient. Inside, soaring ceilings, original wide-plank pine flooring, exposed beams, custom built-ins, and three fireplaces create an atmosphere rich with warmth and character. The expansive main living space is designed for effortless entertaining, where an open-concept great room flows seamlessly into the dining area and chef's kitchen featuring a Sub-Zero built-in refrigerator, generous eat-in space, and handcrafted details throughout. French doors open onto an elevated balcony overlooking the stunning stone courtyard and heated pool. The south-facing primary suite is filled with natural light through oversized Andersen windows and offers a luxurious retreat complete with a spacious walk-in closet, double vanity, steam shower, and oversized jetted soaking tub. Additional living spaces include a cozy den with a gas fireplace, a private guest suite with its own full bath, and an extraordinary unfinished upper-level studio beneath dramatic vaulted ceilings-an inspiring canvas for a future primary suite, artist's studio, home office, recreation room, or wellness retreat. The walk-out lower level continues to impress with two additional bedrooms connected by a Jack-and-Jill bath with sauna, a handsome home office lined with custom built-ins, an updated fitness room, custom laundry-room with dog shower, recreation room with wet bar and french doors opening directly to the secluded courtyard and pool. Modern improvements complement the home's historic soul, including a DaVinci lifetime composite roof, whole-house generator, three-car garage with workshop, and meticulously maintained landscaping featuring mature trees and pristine grounds. The Peace Barn is an extraordinary residence, offering a rare opportunity for the buyer who appreciates historical architecture, embraces character, and recognizes the rare opportunity to become the next steward of an irreplaceable property. This remarkable estate offers both timeless beauty and endless possibilities for its next chapter.
