Be sure to watch the full motion video tour! Welcome to 401 Sabine Avenue-an exceptional Main Line residence that seamlessly blends classic charm, timeless elegance, and modern convenience. This beautifully maintained 5 bedroom and 3 full plus 2 half bath stone Colonial in the heart of Wynnewood offers 3,258 square feet of above-grade living space, plus a finished lower level adding about 500 additional square feet of living space. The location is truly unparalleled. From just outside your front door, a short stroll brings you to Suburban Square with its fabulous shops and eateries, Whole Foods, the Wynnewood or Ardmore SEPTA stations, and Lower Merion High School (although this location can go to either LMHS OR Harriton HS). In the other direction, enjoy easy sidewalk access to the vibrant downtown of Narberth, known for its charming boutiques, excellent dining, lively community events, and the beloved Narberth playground. A picturesque flagstone walkway leads to the welcoming foyer of this classic center hall Colonial, where gleaming hardwood floors, elegant millwork, two coat closets, and matching sets of French doors set the tone for the home's timeless character. To the left, the formal living room features rich woodwork, a wood-burning fireplace, and access to a private rear deck, as well as a delightful three-season flagstone solarium filled with natural light. To the right, the formal dining room is perfectly proportioned for entertaining and showcases substantial built-in cabinetry for both display and storage, along with large windows accented by classic wood shutters. The updated kitchen is thoughtfully designed with newer cabinetry, granite countertops, a custom tile backsplash, built-in wine storage, stainless steel appliances, and a professional-grade range. In addition, this first floor boats a versatile and cozy den or home office with a wall of built-ins and direct access to the outdoor deck and yard. Completing this floor is a convenient powder room. Upstairs, the second floor offers a lovely primary suite and a large attached bathroom with a separate tub and shower configuration. Adjacent to the bath is an additional bedroom ideal for a nursery, home office, or guest space. Two more well-appointed bedrooms share a Jack-and-Jill bathroom, completing this level. The third floor provides a private fifth bedroom, a full bath, and a wall of closets offering excellent additional storage. The finished lower level expands the home's living space and features an expansive recreation area with exposed stone walls, a powder room, and a full laundry room with built-in cabinetry. From here, enjoy direct access to the attached 1-2 car (depending on size) garage, complete with a brand new garage door and epoxy floor. Outside, the fully fenced yard offers privacy and mature landscaping, creating a safe and welcoming space for children, pets, or outdoor entertaining. Lastly, you won't have anything to worry about after you move in as the current owners have taken care of so many expensive upgrades. To name a few, they have already removed all of the knob and tube wiring, quite recently installed a BRAND new top of the line, high efficiency heater in January of 2026, installed a new hot water heater in 2025, installed one new zone of central AC also in 2025 and the other in 2021, installed a new garage door in April 2026, replaced all windows with top quality Andersen Windows in 2021, and they replaced the entire sewer line out to the street and installed a new driveway - both in 2018! This classic Main Line home offers timeless architecture, generous living spaces, thoughtful upgrades and an unbeatable walk-to-everything location-truly an exceptional opportunity for its next owners.
