Designed to stand apart, this architecturally distinctive, modern Scandinavian home in Original Town Superior features a separate alley-accessed ADU and sits on a spacious corner lot just steps from historic Grasso Park and Coal Creek. Soaring ceilings create an impressive sense of openness in the main living area, while the kitchen and oversized island anchor the space. A seamless built-in refrigerator, 6-burner gas range, and accent cabinet lighting bring both function and refined modern style to the kitchen. Just off the living area, a large patio extends outdoors to the professionally landscaped yard, while a raised front porch with sleek metal railings and a standing-seam metal roof complement the home's striking modern exterior. The main-level primary suite at the back of the home offers a walk-in closet and private bath, while the expansive upper loft is perched above the living area. Rounding out nearly 2500 sqft in the main home, the finished basement adds a generous recreation room, 2nd bedroom, full bath, laundry with washer/dryer, and plenty of storage. At the rear of the property, a separate 665-sqft ADU adjoins the extended 2-car garage, both with convenient alley access. The ADU offers its own kitchen, living room, private bedroom, 3/4 bathroom, and laundry closet with washer/dryer. It features views of the open-space trail that crosses a scenic bridge over Coal Creek and winds through the park, connecting to Boulder County's extensive Coal Creek Trail network. Original Town also offers convenient access to Founders Park, Target, Whole Foods, and Costco, with the added benefit of no HOA dues or additional metro district taxes.
