Situated on one of East Mt. Airy's most picturesque and sought-after blocks, 312 E. Gowen Avenue is a rare and beautifully preserved Frank Furness stone twin. Originally part of the renowned Gowen Estate established in the 1880's, this home offers timeless architecture, gracious living spaces, and extraordinary gardens on over half an acre. Rich in character and architectural detail, this exceptional 5-bedroom, 2 full baths, 1 powder room residence seamlessly blends historic craftsmanship with modern livability in one of Philadelphia's most beloved neighborhoods. First time offered in over 60 years, this is a truly special opportunity to own a cherished home with remarkable history and preservation. Set back from the street behind mature trees and sweeping lawns, the home's striking Wissahickon schist façade, steep gables, deep covered front porch, and oversized chimney create a storybook presence with undeniable curb appeal. The expansive porch overlooks thoughtfully cultivated gardens and lush seasonal plantings, offering a peaceful setting for relaxing among the blooms. Inside, sun-filled formal living and dining rooms showcase remarkable original woodworking, rich hardwood flooring, oversized windows, crown moldings, picture rails, built-ins, and woodburning fireplaces. A spacious first-floor office/library with custom built-ins and an additional woodburning fireplace provides the perfect work-from-home retreat, reading room, or den. At the heart of the home is a large eat-in kitchen with center island, abundant cabinetry, and direct access to a beautifully restored gardening shed and rear grounds. A secondary staircase off the kitchen leads to a private upper-level bedroom, ideal for guests, studio space, or an additional office. The second floor features two additional generously sized bedrooms, including a spacious primary suite with a woodburning fireplace and an adjoining sitting room/home office en suite, offering endless opportunities to create a dressing room, reading lounge, or work-from-home space. The third floor offers an additional bedroom, a full bath/laundry space, and a large rec room/playroom with treetop views, providing flexible living space for guests. Throughout the home, original wood trim, solid doors, deep windowsills, and historic detailing create an atmosphere of warmth, elegance, and authenticity. Outside, the property continues to impress with mature landscaping, extensive gardens, and a large private driveway offering ample parking. The location is exceptional and just steps from the Mt. Airy train station for an easy commute to Center City, and moments from the shops, cafés, and restaurants along Germantown Avenue. Nature lovers will appreciate the close proximity to Fairmount Park and the Wissahickon trails. This is a rare opportunity to own an architecturally significant property within the Gowen Estate story.
