Welcome to 551 Spade Place, an extraordinary custom-built retreat nestled in the coveted Lost Park Ranch community of Jefferson, Colorado. Perched on 5 acres of serene mountain landscape, this one-of-a-kind 3-bedroom, 3-bathroom home offers a lifestyle of peace, privacy, and self-sufficiency—where breathtaking views are your daily backdrop. Designed with sustainability at its core, no detail or expense was spared. Nearly off-grid, the home operates on a 6kW solar electric system, complemented by a 260-gallon solar thermal water storage tank powered by five ground-mounted panels. The standing-seam steel roof boasts an impressive R-value of 60, and the triple-pane windows are sealed so efficiently that an air exchanger was installed to ensure optimal indoor air quality. Indoor and outdoor LED lighting enhances energy efficiency throughout the property. Radiant in-floor heating warms both the main and lower levels—as well as the garage floor—for year-round comfort. The lower level also features a convenient kitchenette, ideal for guests or extended stays. The home includes Mr. Lightening grounded electrical protection for added peace of mind. A spacious two-story shed with electricity and propane radiant heat offers flexible space for hobbies, a workshop, or additional storage. Unwind in your private wood-fired sauna, listen to the soothing sounds of the custom water feature, and let the stress of the day melt away. Nature lovers and fly-fishing enthusiasts will revel in the included membership to the prestigious Tarryall Fishing Club, granting access to over 14 miles of Tarryall Creek—upstream from the renowned Gold Medal trout waters. This is more than a home—it's a sanctuary of smart design, artisan construction, and harmonious mountain living. 551 Spade Place is a rare gem that must be experienced to be truly appreciated.
