Randy McCallister, listing agent at Goodman Realty Arkansas-Marshall, says: "When you walk in, you're blown away by the craftsmanship, handiwork and labour that went into building this house. It's almost like a museum - there's a lot of handiwork in this house."

The home was completed in 2017 and is currently listed for $2 million.

The Earth House is a sustainable design concept that calls for the use of natural and recyclable items, such as earthbag tyres, as building materials.

The entire place is completely off-grid, with solar panels, a water catchment system, a generator and a composting toilet.

McAllister said, "It's absolutely unique in this area - there are more places like this in the desert than here." He added that the seller had to make some adjustments to the design to accommodate Arkansas' sometimes humid climate.

One of the quirks of the layout? There isn't much privacy inside the main house.

McAllister notes, "The bedrooms don't have any doors. There are no doors inside the house at all, except for the bathrooms. The whole inside of the house is open air."

The kitchen is circular, and the fireplace is designed to radiate heat into the house rather than out through the chimney.

McAllister said determining the unit price was a little difficult.

"It's one-of-a-kind," he said, adding that the small county has only about 8,000 people." （There's nothing like it (here)."

The house sits at the highest point of the property on Schnauzer Lane, named for the seller's pet project - dog ownership. In fact, there is a large kennel next to the guesthouse.

McAllister explains: they built the house so that the dogs could go outside for fresh air, but the dogs could also come in under the roof of the guesthouse.

The listing also comes with a summer cottage and a workshop/utility/garage building. There is also a screened-in shed for outdoor entertaining.

The home's rural setting is certainly part of its appeal.

It's in the middle of nowhere, except for its proximity to the Buffalo National River, which is a U.S. national park," McAllister says. He predicts the buyer will likely be "someone who enjoys hunting and the outdoors and has enough money for a second home."
