A rare offering after only two owners in its lifetime! Welcome home to one level living in a very quiet, secluded location on a private cul-de-sac street within the top-rated Wallingford-Swarthmore school district. This fantastic custom-built, stone and white brick, 4 bedroom, 3 full bath home sits proudly on nearly an acre lot complete with a fenced-in tennis court with a squash wall and basketball court. A convenient entry with parquet floor leads you into an expansive Great Room boasting a raised hearth stone fireplace with built-in shelving, wall of windows, including a large bay window with custom-made floor to ceiling rolling wood shutters. The eat-in-kitchen features engineered hardwood floors (2021), a large center island, gorgeous granite countertops (2017), stainless steel appliances, Oak cabinets, Bosh double oven (2017) and a breakfast area bathed in natural light from a second bay window that overlooks the gardens, gazebo and tennis court. A door from the kitchen leads out to a tiered deck offering beautiful views and includes a glider swing and greenhouse for easy access to all your homegrown veggies and herbs. Stairs lead down to a covered patio, made private by remnants of an old stone wall complete with arched doorway leading to the driveway. There is also an outdoor powder room, which sellers found beneficial for use during outdoor entertaining and those long-running tennis matches. The gazebo offers the perfect shaded spot to watch a match of tennis or enjoy a warm-weathered evening. Back inside, the kitchen also has access to the attached 2-car garage, laundry room and a finished basement room ideal for a den, in-home office or game room pool table included! Off the other end of the Great Room a short hallway that takes you back to a secluded in-law suite with 4th bedroom, en-suite full bath and its own exterior access. A long hallway off another side of the Great Room is where you will find three more bedrooms, including the Primary Bedroom designed with cabinetmaker grade built-in bedside tables and bureaus, bay window with rolling wood shutters, huge walk-in closet and attached Primary Bath with dual sinks, a dressing area and oversized Jacuzzi. The other two bedrooms share the hallway full bath. One is well-sized, has new engineered hardwood floors, and a ceiling fan. The other one is currently used as an office. The property also includes a detached barn with one-car garage and two upper level rooms providing a perfect opportunity to turn this bonus space into a workshop, music room or art studio. PLUS: New roof and gutters with gutter protection (2021), waterproofed crawl space (2021), Aprilaire dehumidifier in the crawl space (2021), a backup propane power generator and switchboard to power essential parts of the house in the case of a power outage.
