Welcome to this superb four-bedroom, three full and one-half bath Colonial located on a quiet cul-de-sac on a no-thru street in sought-after Cashell Manor! Over 4,000 sf of finished space on three levels. Meticulously maintained, the list of improvements over the years is impressive. The heart of the home features a gourmet kitchen with Miele and Bosch stainless steel appliances, including a full-size double wall oven, 42" maple cabinets and soft-close drawers, quartz countertops, and a breakfast bar. The kitchen opens to a large light-filled family room addition with a vaulted ceiling and recessed lights (2009). It also opens to an all-season sunroom with a Mitsubishi wall unit (2022), which is connected to a composite deck (2022). Also on the main level is a half bath, a sizable separate dining room, an additional living room with a wood-burning fireplace, and a mud/laundry room with access to the two-car garage and the backyard. On the upper level, the primary bedroom has a fully renovated en suite bath with a walk-in shower with glass doors and an enormous walk-in closet. There are three other good-sized bedrooms, all with ample closet space and a fully renovated hall bath with a tub/shower. The fully finished lower level (2022) features recessed lighting and LVP flooring throughout, a recreation room with a wet bar, quartz countertops, maple cabinets, and a stainless steel Kenmore refrigerator. There's a full bath with a tub/shower, a room that could be an exercise room/office/additional bedroom, and a generous storage room. Other features include newer main and sunroom roofs (2025 & 2023), double-pane vinyl windows throughout (2018), a new driveway (2025), and more! Great location! Cashell Elementary is only a block away, Norbeck Country Club is two blocks away, and the Norbeck Hills pool, tennis court, and tot lot are four blocks away. Georgia Avenue is a little over a mile away, and the ICC (200) exit, along with all Olney has to offer, such as the Village Center, Theater, and library, is between two and three miles away.
