A work of art inside and out. Meticulously handcrafted using shipping containers, reclaimed wood and steel, this outstanding 4,000+-square-foot residence is a marvel in design, functionality, and energy efficiency. Sited on an elevated 9,375 square-foot lot, the home frames breathtaking views in every direction, including huge iconic Flatirons views to the south, unobstructed Red Rocks and Foothills views to the north, and eastern vistas over Downtown Boulder. Flooded with abundant natural light, and featuring multiple indoor & outdoor living spaces, this home is designed to take advantage of all that Boulder has to offer.


Arrive on the 1,800+-square-foot, open main level to find concrete floors, oversized windows and soaring ceilings finished with 100-year-old barn wood dotted with recessed and designer lighting. The open concept kitchen/dining can accommodate a dinner party of any size and dazzles with custom Scandinavian minimalist cabinetry, concrete counters, a farm sink and professional-grade appliances, including a gas range and industrial glass-door refrigerator. Enjoy seamless indoor-outdoor living thanks to a glass-and-steel garage door that opens the living room entirely to a patio and well-equipped outdoor kitchen and fire pit, backed by unobstructed views. A convenient bedroom suite, a guest bathroom and laundry room complete the expansive main level.


Above, two 53-foot shipping containers comprise the 1,200-square-foot upper level. The home's south staircase is both functional and a work of art, featuring an industrial steel tube and concrete and steel treads that lead to two secondary bedrooms with walk-in closets and a shared full bathroom. One of these bedrooms has its own private deck and the other opens to a 500 square foot deck shared with the master bedroom to the north. The master suite has a huge walk-in closet, unobstructed views from the bed, a sitting area, two additional private decks, a stunning master bathroom, and its own staircase. The second level also features convenient washer-dryer hookups for the addition of an upstairs laundry room. 


The large, loft-like basement features high ceilings, concrete floors, walls of bookcases, and adds flexible living and storage space. The oversized two-car detached garage, also custom built from shipping containers, offers excellent flexibility and additional storage.


A focus on energy-efficiency results in incredibly low utility bills for this spacious home - less than $160 per month during the coldest months. The 5.8KW solar system net produces on an annual basis, and high-efficiency double-pane windows run throughout. In-floor radiant heat delivers year-round comfort, and the Insulated Concrete Form (ICF) basement stays at a moderate 69-73 degrees year-round.


This exceptional home is located on a quiet, cul-de-sac in the gorgeous Flagstaff neighborhood with immediate access to abundant trailheads, Chautauqua Park and attractions, the Fox Theater and the University of Colorado campus. Downtown Boulder and the Pearl Street mall is an easy, five block stroll to the North. Pearl Street features award winning restaurants, bustling coffee shops, locally owned retail shopping, and much more. Situated at the foot of the Flatirons, the Chautauqua neighborhood is a haven for those who love Boulder’s famed Open Space and dramatic vistas.
