A rare opportunity in the foothills of Lyons, this 13-acre pastoral retreat offers a wonderful lifestyle and easy proximity to town. Designed in consultation with renowned sustainable architect Michael Reynolds of Earthship Biotecture, the home draws inspiration from Earthship principles but is conventionally built, offering the best of both worlds: sustainable design without sacrificing daily comfort, utility, or aesthetics. This 3-bedroom, 3-bath home is a study in sustainable elegance and purposeful design. Vaulted ceilings, expansive windows, and a passive solar layout fill the space with warmth and light. The integrated greenhouse room is a thriving, year-round tropical oasis with mature banana, fig, and olive trees. Interior windows open into the greenhouse room, allowing natural light and lush greenery to serve as a living backdrop to the home's main living areas, blurring the line between indoors and nature in the most beautiful way. At the heart of the home's sustainability is a sophisticated rainwater harvesting and purification system. It is more efficient and often more abundant than many of the area's lower-producing wells. The land itself is level, usable, and quietly pastoral, with panoramic views of Blue Mountain, fenced gardens, a dedicated space for animals or small livestock, and a detached outbuilding ideal for an artist studio or workshop. Convenient two-car attached garage. The Little Thompson River winds along the edge of the property, offering private riverfront access and the soothing sound of water as part of the everyday experience. You don't just live here. You plant, create, restore, and reconnect. This is a one-of-a-kind property for those who want to live intentionally and beautifully. Less than nine minutes to Planet Bluegrass and the shops and restaurants of downtown Lyons, and under 30 minutes to Boulder or Longmont.
