for $1,249,000 with 5 bedrooms and 5 full baths, 3 half baths. This 5,645 square foot home was built in 1840 on a lot size of 1.32.
A rare historic estate in Newtown Square, The Edgar House offers nearly 6,000 square feet of livable space on more than 1.3 private, lushly landscaped acres in one of Delaware Countys most established and sought-after locations. Originally built in 1840 and thoughtfully expanded in 1910 and 2008, this Federal-style landmark blends timeless American architecture, estate-scale privacy, and exceptional flexibility for todays luxury buyer. Set quietly off the road, the home immediately conveys a sense of permanence and character rarely found in modern construction. Thick stone walls, real hardwood floors, detailed crown moldings, multiple fireplaces, and classic architectural proportions speak to the craftsmanship of another era, while the homes expansive layout provides the scale and versatility todays buyers demand. Spanning three full stories plus a finished basement, the residence offers 5 bedrooms, 8 bathrooms, a den, and an intelligent floor plan suited for multigenerational living, entertaining, working from home, or creating a private compound-style retreat. The great room layout opens the home for everyday living and gatherings, while two ensuite primary bedrooms provide comfort, privacy, and flexibility. Historic details are found throughout, including front and rear staircases, rich millwork, and a rare interior smoke room that nods to the propertys storied past. Practical updates, including an updated shingle roof and a Viking gas appliance package in the kitchen, help balance the homes old-world substance with modern livability. Outside, a 1,600-plus square foot wraparound deck and patio overlook mature landscaping, creating a private outdoor setting designed for entertaining, relaxing, and enjoying the acreage. A circular driveway enhances the estate-like arrival, while the detached three-car climate- controlled garage adds both presence and function. A separate office space further expands the propertys utility, opening the door for a home-based business, studio, creative workspace, or private professional use. The property also offers meaningful future upside, with room to expand the existing residence or potentially add a secondary structure, subject to applicable approvals. The Edgar House is more than a home. It is a local landmark with architectural significance, real substance, and long-term equity potential. For the buyer seeking privacy, scale, historic character, and opportunity in the heart of Newtown Square, this is a singular chance to own, personalize, and steward one of Delaware Countys most distinctive estate properties.
