Rare opportunity to own this Radcliffe model Grand Colonial in hot hot hot Keene Mill Station near Orange Hunt and West Springfield! Unique, very spacious main-level addition with extra full bathroom and built-in bookcases - can be used as an entry level bedroom but currently configured as a beautiful sunroom - a private and light-filled oasis surrounded by windows and skylights overhead. This home features a handsome brick exterior with all the colonial details, and widened concrete and pebble driveway leading to one-car garage. One enters thru the doorway with sidelights and Palladian details, to a center hall foyer and elegant half-spiral stairway. Flanking the main stairway, one finds a separate formal dining and living room. Passage from the dining room leads past the laundry/mud-room with door to garage, and a butler's pantry, to the nicely updated (all new appliances 2023) and open-plan kitchen. Ample room for the breakfast area and pantry closet, leading to a traditional family room with mantled gas fireplace. Sunroom addition is just off the kitchen and breakfast area. Up the grand staircase, one finds a primary bedroom with a newly remodeled private bathroom, and three additional bedrooms and a hall bath. All rooms are generously sized with ample closet space. The owners have recently finished (with all the proper permits - finished after 2023 tax assessments were issued) most of the basement into a very cozy and usable recreation room, with plenty of storage and the possibility of adding a bath and/or wet-bar in the future. Potential to upscale this finished space into a media room or theatre area, or use as currently configured as a game room, recreation room or gym. Behind the home lies a well-landscaped and quite expansive rear yard, mostly fenced and with a shed. Recently repainted deck on side has plenty of space for bbqs, parties or just reading a book with a glass of wine. Only one owner ever - this home has been lovingly cared for over the years. Conveniently located just minutes from downtown Springfield, I395, Fairfax County Parkway and the Springfield Metro (bus lines run very near-by), near Whole Foods, Lidl, and Hidden Pond Nature Center. About one-half hour to Ft Belvoir, The Pentagon, Amazon HQ2, Tysons, or Reston - you couldn't ask for a more central, yet tranquil location! New roof 2022, Leaf Fitter Gutter Guards 2020, windows, gutters and insulated vinyl siding 2011.
