Property Description
Walk to Alpine Modern for coffee, Chautauqua Park for a hike, CU for a performance and downtown Pearl Street for shopping and restaurants, all from the coolest house in town. Designed & built by mid-century modern architect Charles Haertling for the Wilson family, this landmarked home was inhabited by the Haertling family from 1973 - 2021. Known for his organic architecture, Haertling designed homes to feel at one with the natural surroundings and this one exemplifies this concept in an inspiring way. Note the clover shaped symmetry, cascading roof and ubiquitous nautilus design structures topping the support beams. The open concept main living area is created for comfort and easy entertaining with wood-burning fireplace, vaulted beamed ceilings, clerestory windows and abundant southern light, accessing two expansive decks & terraced gardens that substantially extend the indoor living space. The kitchen is tucked behind the curved clover petal wall of the dining area with bar seating, open shelving, counter height windows, with vintage tile on floor and countertops. The primary suite is a private perch in the peak of the roof, another bedroom with private balcony is on the main level and two large bedrooms are on the garden level, each with private outdoor access, anchored by a family room that accesses a south-facing backyard patio. Also on this level: cozy office/yoga room. Recent updates, including new A/C, perimeter fence, Philips Hue remote lighting and a mini-split in the enclosed primary suite, make this a move-in ready property where one can immediately begin enjoying the amazing lifestyle this coveted location offers. Walk to miles of open space trails and a remarkable variety of nearby shops and restaurants, not to mention Boulder's famed downtown Pearl Street, CU Boulder and Chautauqua Park for concerts, movies, lectures, sledding, tennis and so much more.
