Rarely does a fully updated and well-maintained rowhome with a lower level that has a separate Certificate of Occupancy come to market on a lovely tree-lined street in Columbia Heights. This special offering presents a compelling opportunity for an owner to have access to both spaces or to principally live in one space and utilize the other as an income-producing asset. Behind a classic covered front porch, the main level welcomes you to an open floor plan where five-inch oak flooring, refined crown molding, a slate fireplace, built-in ceiling speakers, and original exposed brick highlight the living spaces. The gourmet kitchen is appointed with leather-finished stone countertops, abundant cabinet space, a Thermador French door refrigerator, stainless steel Bosch appliances to include a 5-burner gas cooktop, and a pot filler for added convenience. The kitchen island provides utility and functionality with additional counter space, a double sink, and breakfast bar seating, all overlooking the bright separate dining area. Upstairs, the primary suite showcases a soaring ceiling, spacious walk-in closet, and en suite bath with a walk-in shower. A private staircase leads to a 240-square-foot rooftop deck, providing an intimate escape above the city. Two sizable bedrooms, a full bathroom, and bedroom-level laundry complete this approximately 1,900 square feet residence. With separate front and rear entrances, the lower level is equally considered. Porcelain tile flooring, wainscoting, recessed lighting, and a blue slate fireplace bring texture and distinction to the 850 sqft one-bedroom residence. The kitchen echoes the finishes above with leather-finished stone countertops, a Thermador refrigerator, and stainless steel Bosch appliances. The bedroom features a walk-in closet and en suite bath, complemented by an additional powder room and full-size laundry. Built-in ceiling speakers extend throughout. A fenced rear outdoor space completes this exceptionally versatile Columbia Heights offering.
