Property Description & Video
601 15th St, Boulder, COVideo Tour of 601 15th St, Boulder, CO.
AT THE BASE OF THE FLATIRONS, JUST BLOCKS FROM CHAUTAUQUA PARK AND BOULDER'S LEGENDARY TRAIL SYSTEM, 601 15TH STREET pairs an irreplaceable setting with a beautifully transformed interior. Set on a meticulously landscaped 9,818-square-foot corner lot, this 5,280-square-foot, five-bedroom residence is surrounded by mature trees, offering exceptional privacy while remaining just minutes from downtown Boulder. Step outside and some of Boulder's best hiking and open space are practically at your doorstep. The interiors have been professionally renovated with a lighter, more contemporary aesthetic. More than $500,000 has been invested in upgrades and renovations. The redesigned kitchen features new countertops and Wolf and Sub-Zero appliances, complemented by white oak flooring, smooth-coat walls and fresh paint throughout. The living room was reimagined with new windows, custom cabinetry and a central fireplace with a refined tile surround. The flexible floor plan includes a private main-level office and a second primary or guest suite. Upstairs, the primary retreat features a private balcony, an expansive reconfigured custom walk-in closet and a renovated spa bath with soaking tub, steam shower and radiant heat. Two additional ensuite bedrooms and upper-level laundry complete the floor. French doors connect the main living spaces to a private stone courtyard designed for entertaining, with an outdoor kitchen, dining area, fire-pit lounge and cafe lighting. Mature gardens, a hot tub and full-size sauna create a remarkably secluded outdoor retreat. A finished walkout lower level adds family and recreation spaces, a bath and generous storage. A detached two-car garage, EV charging, solar and smart-home features complete a rare opportunity to enjoy the best of Boulder-immediate access to the Flatirons and Chautauqua, exceptional privacy among mature trees, and a meticulously updated home in one of the city's most compelling settings.
