About this home

Public Remarks: Historic charm meets modern luxury in this elaborate home facing 11th Street. Extraordinary indoor-outdoor living with multiple exterior entrances and high-end bi-fold doors open to a secluded, lush, lovingly maintained garden. The skylit chef's kitchen features Viking appliances, including 6-burner stove, and custom floor-to-ceiling walnut cabinets. Rarely found in historic homes, this home offers an oversized master bathroom with a soaking tub and walk-in closet. Thoughtful updates include a large brick privacy wall lined with mature trees, Argon-filled windows, and double insulated walls. You can hear a pin drop in this house! Work from home with Fiber gigabit internet, and generate additional income via Airbnb while you are vacationing. Home comes with 4k hi-res security cameras and radiant floor heating. 1 block from Chautauqua, miles of trails, & ample street parking right outside the home. This is truly one of Boulder's best-kept secrets.
