This 81-acre estate is a masterwork of eco-conscious design, featuring an earthen eco-home meticulously hand-sculpted from cob (monolithic adobe) and straw bale.

The result is a home that maintains a comfortable temperature year-round and stays naturally cool. Oriented due south, the home is bathed in light through expansive glazing, highlighting interior walls finished in white kaolin clay plaster and a traditional poured adobe floor. At its heart, a massive Douglas fir timber frame milled on-site showcases authentic mortise and tenon joinery, rising to hand-finished ceilings. The property is a true wellness retreat, designed for those seeking a private haven. The home & land border a spiritual, intentional community based on yoga & meditation.The three large custom Damanhurian stone spirals, built by artisans from Northern Italy serve as powerful tools for meditation and energetic alignment.
