A rare gentleman's ranch where sustainable architecture meets artisan craftsmanship on 8.8 secluded acres with unobstructed views from Pikes Peak to Longs Peak, the Flatirons, and Boulder's city lights. Originally designed by renowned solar architect Richard Crowther and meticulously reimagined from 2017-2022, Haystack House is a masterclass in passive solar design and modern luxury. Highlights include hydronic heated floors, Kolbe commercial-grade windows, solar energy, 23-foot cedar-beamed ceilings, and reclaimed Beetle Kill Pine floors throughout. The chef's kitchen features custom cabinetry, Thermador appliances, Lefroy Brooks fixtures, and dual dishwashers. Multiple living suites with spa-like baths and private entries offer flexible living options. The lower level includes gym, steam shower, lounge, kitchenette, and vineyard-facing patio. Outside: one-acre stocked pond with island, dock, fire pit, and footbridges. 45 total water shares (20 Left Hand + 25 New Table Mountain) feed a complete irrigation system. Custom 1,200-SF Morton Barn with 28-foot ceilings, heated slab, kitchenette, workshop, and solar panels-ideal for artists, hobbyists, or future ADU/equestrian conversion. Chicken coops, raised gardens, established vineyard, asparagus field, and dog run complete this self-sustaining lifestyle property. Surrounded by organic farms and open space, minutes from downtown Niwot and Boulder. A cinematic Colorado backdrop for collectors, filmmakers, creatives, and future Sundance Film Festival attendees seeking privacy without isolation.
