5952 Oxford Niwot, CO 80503

Originally designed by solar pioneer Richard Crowther, Haystack House is one of Colorado's most quietly remarkable estates. Sited on 8.84 secluded acres in Niwot with 360-degree unobstructed views spanning Pikes Peak to Longs Peak, the Flatirons, and Boulder's city lights. Ten minutes from downtown Boulder, three minutes from downtown Niwot, with easy access to Longmont, Lyons, Denver, and Fort Collins. Secluded yet extraordinarily central.
The architecture earns its pedigree. Passive solar design, 23-foot cedar-beamed ceilings, hydronic heated floors, reclaimed Beetle Kill Pine floors, and Kolbe commercial-grade windows throughout. Net-zero solar with average utility costs of approximately $400 per month for the entire estate. Every material chosen for longevity and beauty.
The chef's kitchen is built for serious use: custom cabinetry, Thermador appliances, Lefroy Brooks fixtures, dual dishwashers, and handmade tile that catches the sunset. Multiple living suites offer private entries and spa-caliber baths with soaking tubs and artisan tile. The lower level runs its own logic with a gym, steam shower, lounge, kitchenette, and vineyard-facing patio.
Outside, a stocked one-acre pond with island, dock, fire pit, and dual footbridges. An organic vineyard, gardens, asparagus field, chicken coops, composting systems, and 45 water shares feeding a full irrigation system. The 1,200 SF Morton Barn with 28 foot ceilings, heated slab, solar, workshop, kitchenette, and glass roll-up door is ready for an artist, an equestrian, or a future ADU.
This is a property that entertains as beautifully as it operates. The grounds have hosted farm dinners, weddings, and private events against a backdrop that cannot be manufactured. For the hobby farmer, the creative, the entertainer, or simply someone who wants Colorado in its most serene and unspoiled form, Haystack House is a rare and complete offering.
