Welcome to 673 Ardmore Avenue, a distinguished and historically significant residence set on an expansive .83-acre lot in the heart of Ardmore’s prestigious Main Line. Originally constructed in the early 1900s on land once owned by the estate of J.B. Biddle, this home was built for John S. Arndt, a prominent member of the Philadelphia Stock Exchange. Over the decades, it has been home to some of Philadelphia’s most notable families, including C. Addison Harris Jr., and has long been regarded as a symbol of sophistication, prominence, and enduring legacy. A beautifully preserved example of early Main Line architecture, the home offers timeless elegance combined with modern comfort—all within close proximity to Merion Golf Club, Suburban Square, Haverford College walking trails, top-rated schools, and convenient regional rail and Amtrak service. Step inside to discover classic Ardmore craftsmanship seamlessly integrated with modern amenities. The main level showcases exquisite original millwork, wood floors, three fireplaces (two adorned with original Mercer tiles), custom built-in bookcases, French doors, and deep-silled windows that enhance the home with natural light. The gracious and flexible floor plan adapts effortlessly to your lifestyle. A grand reception foyer leads to two large living spaces—ideal for entertaining, relaxing, or working from home. The gourmet kitchen is a chef’s dream, complete with high-end appliances, abundant custom cabinetry, and an inviting atmosphere for everyday living or special occasions. A powder room and mud-room are also found on the main level. Upstairs, you'll find five spacious bedrooms, a charming sleeping porch and three bathrooms. The second-floor bedrooms offer generous closet space, while the bathrooms are tastefully updated with elegant finishes. The unfinished third floor presents incredible potential—perfect for a great room, art studio, yoga retreat, or additional guest suite. Outdoors, a private brick patio provides a serene setting for entertaining and enjoying the beautifully landscaped grounds. Additional features include central air conditioning and efficient forced air heating, blending old-world charm with modern practicality. Located near the coveted Merion Golf Manor enclave of Haverford Township, 673 Ardmore Avenue offers a rare combination of tranquility and accessibility. Enjoy being just minutes from Suburban Square’s dynamic shopping and dining scene, scenic Haverford College trails, and the Ardmore Train Station with direct access to Center City Philadelphia and Amtrak routes to New York, Baltimore, and Washington, D.C. This remarkable residence is a rare opportunity to own a piece of Main Line history—crafted with care, preserved with pride, and designed for contemporary living.

As a licensed real estate brokerage, Estately has access to the same database professional Realtors use: the Multiple Listing Service (or MLS). That means we can display all the properties listed by other member brokerages of the local Association of Realtors—unless the seller has requested that the listing not be published or marketed online.
The MLS is widely considered to be the most authoritative, up-to-date, accurate, and complete source of real estate for-sale in the USA.
Estately updates this data as quickly as possible and shares as much information with our users as allowed by local rules. Estately can also email you updates when new homes come on the market that match your search, change price, or go under contract.
