A home built from rammed-earth tires and recycled bottles can stay comfortable through sub-zero Rocky Mountain winters without a single heating bill. That is not a theoretical claim. This rare off-grid “Earthship” in Wyoming just listed for $625K, and the property offers a real-world test case for how radical sustainable architecture performs outside the deserts of New Mexico, where the concept was born.

Located at 1395 Fletcher Park Road near Wheatland, in the Laramie Peak foothills of Platte County, the home has drawn attention from national real estate outlets and international press alike for its tire-packed walls, 66-foot greenhouse, and fully self-contained utility systems [1][2][3].

Key Takeaways

• This rare off-grid Earthship in Wyoming just listed for $625,000, covering about 1,500 square feet, 2 bedrooms, and 1 bathroom on roughly 55 acres [3][4][5].
• The walls are built from approximately 1,343 pounded tires packed with earth, plus thousands of recycled bottles and cans, creating thick thermal mass [1][2][3].
• Passive solar design and a buried geothermal air-exchange system keep indoor temperatures between roughly 62 and 82 degrees Fahrenheit year-round without mechanical heating or cooling [3][4].
• Power comes from a 2,180-watt solar array, a wind turbine, and a backup diesel generator feeding a 2024 battery bank still under warranty through 2029 [3][4].
• Water is self-supplied through a 1,658-square-foot metal roof catchment system, four cisterns, and a permitted backup well [4].

The Engineering Behind This Rare Off-Grid Earthship in Wyoming

Earthship architecture traces back to architect Michael Reynolds, who began experimenting in New Mexico decades ago with homes designed to run independently of public power, water, and sewer grids. The core idea relies on thermal mass, passive solar orientation, and self-contained systems for water and waste. The Wyoming property follows that same blueprint, but in a much colder climate, which makes its performance data especially notable.

The home’s walls are packed with about 1,343 tires filled tightly with rammed earth, a technique that creates dense, heavy mass capable of absorbing and slowly releasing heat [1][2][3]. Thousands of reclaimed bottles and cans are worked into the interior, forming decorative light-catching patterns while adding further insulation and texture [1][2]. Hand-troweled plaster finishes soften the industrial materials into something that reads as warm and organic rather than utilitarian.

A roughly 66-foot greenhouse corridor runs along the south-facing side of the structure. This space does double duty: it acts as a thermal buffer that moderates temperature swings between outdoors and the living quarters, and it also functions as a year-round growing area for food production [1][4]. The home is bermed into a south-facing hillside, meaning earth is piled against the back and sides, which further insulates the structure and reduces exposure to Wyoming’s harsh winter winds.

Why does this matter for cold climates? Earthships are commonly associated with mild desert environments. This listing demonstrates that with the right berm depth, glazing angle, and thermal mass, the design can hold steady interior temperatures in the 62 to 82 degree range without furnaces, air conditioners, or fans, according to details provided in the listing [3][4]. A buried geothermal air-exchange system supplements this by drawing stable-temperature air from underground into the living space.

Off-Grid Systems That Make This Rare Off-Grid Earthship in Wyoming Fully Self-Sufficient

Beyond heating and cooling, the property is marketed as genuinely 100 percent off-grid, meaning it produces or captures everything it needs without connecting to municipal utilities [3][4].

Power generation includes:

• A 2,180-watt solar array for primary daytime electricity
• A wind turbine to supplement generation during low-sun periods
• A backup diesel generator for extended cloudy or calm stretches
• A 2024 battery bank, still under manufacturer warranty through 2029, that stores power for nighttime and backup use [3][4]

Water independence comes from a 1,658-square-foot metal roof that channels rainfall and snowmelt into four separate cisterns, with a permitted domestic well as a secondary source [4]. An integrated indoor botanical greywater cell is part of the broader Earthship design philosophy, recycling household water through plant beds before it is reused or released, reducing dependence on conventional septic infrastructure.

The surrounding land adds to the appeal. The 55-acre parcel borders or overlooks roughly 280 acres of Bureau of Land Management land, offering privacy and open space without requiring ownership of every acre in view [1][3]. The location sits under 30 minutes from downtown Wheatland and about an hour north of Cheyenne, keeping the property remote without being fully isolated from services [1][3].

Turnkey Off-Grid vs. DIY Homestead Construction

Buying this rare off-grid Earthship in Wyoming at $625,000 raises an obvious comparison: how does purchasing an established, permitted off-grid home compare to building one from scratch?

DIY Earthship construction typically involves significant hurdles. Tire-packing is labor intensive, often requiring months of manual work. Permitting for alternative construction methods, greywater systems, and off-grid septic solutions can be slow and inconsistent across counties. Sourcing qualified contractors familiar with rammed-earth or earthen construction adds further delay and cost uncertainty.

By contrast, this property is already built, tested through roughly 15 years of occupancy since its original construction around 2011, and fully permitted [3]. The listing, handled by #1 Properties Ranch and Recreation with agent Rowan Bennett and co-listing agent Holly Allison mentioned in coverage, effectively sells a finished experiment rather than a construction project [2][3]. One owner profile described the search for land as looking for “an Earthship waiting to happen,” reflecting how these projects often start with a vision for lifestyle and landscape rather than a standard home search [2].

At roughly $417 per square foot as of the September 18, 2026 listing date, the price reflects both the specialized construction and the acreage included [4]. As of early October 2026, multiple land-listing platforms, including Land.com and Land And Farm, continued to show the property as active with no recorded sale or price change, suggesting the market is still testing buyer appetite for this kind of niche, sustainable property [3][4][5][7][9].

This rare off-grid Earthship in Wyoming just listed for $625K represents more than a quirky real estate headline. It is a working demonstration that tire-and-earth construction, passive solar design, and self-contained water and power systems can function reliably in a cold northern climate, not just in desert regions where the concept began. For buyers weighing a DIY off-grid build against a finished, permitted property, this listing offers a rare chance to skip years of construction and permitting friction. Anyone seriously considering off-grid living should review the full listing details, consult a real estate agent familiar with alternative construction, and evaluate whether the maintenance demands of solar, wind, and cistern systems fit their long-term goals before making an offer.
