Expanded and updated 1914 stucco cottage blending historic character with modern livability in a prime Westover location. One of the home's most unexpected architectural details is the remarkable 18-inch-thick concrete construction of the original structure, extending from the basement to the attic. Thoughtfully expanded over the decades, the home unfolds from its original gracious foyer, dining room, kitchen, and breakfast area into light-filled living spaces designed for gathering and everyday life. A spacious family room overlooks the deck and expansive backyard, while a later sun-filled addition wrapped in floor-to-ceiling windows and skylights creates a truly special space ideal as a home office, bedroom, studio, or gathering room. The home offers two spacious upstairs bedroom suites and a finished lower level with an additional bedroom, full bath, and recreation room. Set on a rare 0.225-acre lot, the property combines beautifully landscaped front gardens and a charming gazebo with an expansive fenced backyard featuring a large deck, storage shed, and endless possibilities for pets, play, gardening, outdoor living, or future expansion. Recent improvements include a new furnace (2025), heat pump (2023), water heater (2022), fresh interior paint and carpet, newly painted exterior and deck, replacement of deteriorated wood, new gutters, and owned SolarEdge solar panels installed in 2019 with manufacturer warranty coverage through 2031. A truly special home offering timeless charm, flexible living space, and room to grow-all just two blocks from the shops, restaurants, parks, library, and community amenities that make Westover one of Arlington's most beloved neighborhoods.
