615 W Hartwell Ln

This breathtaking mid-century modern residence in the heart of Chestnut Hill and adjacent to the trails of the Wissahickon was designed in the International Style by Montgomery and Bishop in 1958. Listed on the Philadelphia Register of Historic Places, this architectural gem offers a rare fusion of natural beauty, historic charm, and contemporary luxury. Spanning 4,557 square feet across a lush 1.12-acre lot, the home features six spacious bedrooms and six and a half baths. Its organic design showcases floor-to-ceiling glass that cantilevers dramatically over a stream, offering serene views and an immersive nature experience. The main wing boasts a soaring living room with skylights, an open-concept kitchen, and dining space perfect for entertaining. Adjacent is a bedroom wing with four generously sized bedrooms and two full baths. The former in-law suite has been transformed into a lavish master wing, complete with its own living room, private office, and spa-style bathroom. The finished lower level adds even more functional space, featuring a studio, lounge area, exercise room, laundry, workshop, and two additional bedrooms. Outside, you'll find a circular driveway with parking for up to eight vehicles--including a three-car carport--alongside stone retaining walls, a waterfall-fed stream, landscaped gardens, and a deck ideal for relaxing or hosting guests. Interior highlights include hardwood and ceramic tile floors, recessed lighting, cedar closets, a wet/dry bar, and two inviting wood-burning fireplaces. Thoughtful touches like a laundry chute, upgraded kitchen countertops, and a mix of skylights and clerestory windows provide both comfort and character.
