This magnificent home and carriage house occupy 1.25 acres of beautifully landscaped gardens in the heart of West Mount Airy. Designed by Horace Trumbauer, best known for his elegant homes and the Art Museum, this spectacular stone Colonial was built in 1909. Lovingly maintained by the current owners, it remains one of Philadelphia's finest homes, near the peaceful trails of the Wissahickon yet an easy commute via car or train to Center City. The main entrance on Hortter Street opens into a breathtaking center reception hall. Bathed in natural sunlight, it contains a marble fireplace, intricately engraved mantle and a grand staircase. Several adjacent, gorgeous living spaces make an ideal layout for entertaining. The formal living room boasts imported English walnut paneling, hand crafted moldings, built-in shelving, marble fireplace, and French doors to a covered side porch. An elegant formal dining room features another fireplace, hidden cabinets, and French doors leading to a covered back porch with outdoor fireplace overlooking formal gardens. A large eat-in kitchen/family room has a marble island, two high-end LG gas ranges, double sinks, Sub-Zero Refrigerator and plenty of storage, including two large pantry closets. First floor also includes a cozy den/library with Mercer tile fireplace and a powder room. Ascend the gorgeous staircase to a second floor with grand, sunny landing. A sprawling master suite has two fireplaces, 4-piece ceramic tile bath, large closets, and a study opening onto a large sun porch. The family room with pocket doors separates the Master Suite from three additional bedrooms and two full bathrooms. The third floor has an open playroom/den/office with additional space currently used for storage, but lots of potential for next owner to use as additional bedrooms or in-law/au pair suite. The large carriage house with private yard is another great option for in-law or au pair suite or can be rented for income. The first floor is currently used as an artist studio but could return to use as a 4 car garage. Upstairs, the lovely 1-bedroom apartment has original hardwood floors, updated kitchen and bathroom, small balcony, and tons of natural light. If living in historic luxury is your desire, look no further. This is a once in a lifetime opportunity to own a piece of Philadelphia history.
