At the Base of the Flatirons

At 601 15th Street, the Flatirons rise just beyond the neighborhood, Chautauqua Park and its celebrated trail system are only blocks away, and some of Boulder’s best hiking and open space can become part of everyday life. Yet downtown Boulder and Pearl Street remain just minutes away.

Set on a meticulously landscaped 9,818-square-foot corner lot, this 5,280-square-foot residence feels remarkably private, surrounded by mature trees and established gardens.

Inside, the current owners have extensively transformed the home, creating interiors that feel fresh, light and refined. White oak flooring, smooth-coat walls and fresh paint establish a clean contemporary backdrop. The renovated kitchen features new countertops, generous cabinetry and Wolf and Sub-Zero appliances, while the living room has been reimagined around a new central fireplace and tile surround.

The flexible floor plan includes a private main-level office and a second primary or guest suite. Upstairs, the primary retreat opens to a private balcony and features a renovated spa bath with soaking tub, steam shower and radiant heat, along with an expansive custom walk-in closet created by combining two former closets. Two additional ensuite bedrooms and upper-level laundry complete the floor.

French doors open to a secluded stone courtyard with an outdoor kitchen, dining area, fire-pit lounge and café lighting. Mature gardens, a hot tub and full-size sauna create an exceptional year-round outdoor retreat. A finished walkout lower level adds family and recreation spaces, while a detached two-car garage, EV charging, solar and smart-home features provide modern convenience.

601 15th Street brings together what is increasingly difficult to find in Boulder: a meticulously updated home, mature privacy and immediate access to the Flatirons and Chautauqua—all just minutes from the heart of the city.
