Property Description
Experience the magic of one of Boulder's most beloved neighborhoods with this charming single-level home on a beautifully landscaped lot. Offering 3 bedrooms and 2 1/2 bathrooms, the thoughtful floor plan provides both comfort and privacy - the primary suite occupies its own wing with abundant windows, natural light, and direct outdoor access. The fully fenced backyard is a gardener's paradise, lush with flowering plants, mature shrubs, and a living green screen. Relax and entertain around the covered lap pool and spa or simply enjoy the peaceful sound of the seasonal ditch running along the alley. The attached one-car garage off Mariposa adds everyday convenience, while the rear of the lot features an impressive two-story accessory structure. The lower-level houses a one-car garage, 3/4 bathroom, and sauna. Upstairs, a spacious studio with French doors opening to a private balcony offers inspiring flex space - and exciting ADU potential subject to City of Boulder approval. Located steps from Chautauqua Park and miles of open trails, this property delivers the quietude of a tucked-away retreat with surprisingly easy access to Baseline Road and Highway 36 - ideal for commuters heading to Denver, DIA, and beyond.
