Welcome to 4190 Lowell Boulevard, a thoughtfully updated 3-bedroom, 2-bath mid-century brick half duplex in the Berkeley neighborhood. Built in 1954, this front-unit home pairs classic character with nearly 1,900 finished square feet of functional, light-filled living space. The main level features an open living and dining area that connects seamlessly to the kitchen through a breakfast bar. The kitchen offers butcher block counters, stainless appliances, plenty of cabinet space, and a pantry closet. Two generously sized bedrooms and a remodeled full bath complete the main floor. The finished walk-out basement significantly expands your living area with a large conforming third bedroom, a secondary living room with office nook, a 3/4 bathroom, a bonus room ideal for fitness or storage, and a spacious laundry room that also functions as a walk-in closet. The walk-out basement brings natural light into the lower level, while the separate entrance allows for privacy and flexibility, making this space well suited for guests, a home office, or potential rental income. Recent improvements include a new hot water heater (2025) and newer furnace and central A/C (2020). Outside, enjoy a covered front porch, a fully fenced yard framed by mature shade trees, and two off-street parking spaces accessed by the alley. A party wall agreement governs shared elements with no HOA fees. Located moments from retail and dining at 44th & Lowell, less than a mile to either Tennyson Street or Highland Square, and within quick reach of parks, Downtown Denver, and I-70, this property offers exceptional value and abundant space in one of Northwest Denver’s most walkable locations.
