Welcome to 12 Mesa Sea Road, a distinctive Northern New Mexico home on one acre in Arroyo Hondo, where authentic adobe construction, passive-solar design, and thoughtful craftsmanship come together in a truly unique high-desert setting. The 1,756-square-foot, two-story main residence was built in 2001 with real adobe block construction finished with traditional mesa mud, offering the warmth, character, and substantial feel that only genuine adobe can provide. The entire south side of the home incorporates Trombe walls, harnessing passive solar energy and adding to the property's detuned Earthship character, Earthship-inspired in its design and sustainability features, yet comfortably connected to the grid. Inside, the three-bedroom, two-bathroom home features poured concrete floors, a beautiful soapstone fireplace, high-end finishes throughout, and a propane water heater. The home was re-stuccoed in 2019 and is topped with a pitched metal roof. Adding exceptional versatility is an approximately 900-square-foot frame-and-stucco studio/workshop, built in 2019 and equipped with electrical. Whether envisioned as an art studio, workshop, creative space, or additional flex space, it offers tremendous possibilities. Sustainability continues outdoors with a 5,000-gallon rainwater catchment system consisting of two 2,500-gallon tanks, collecting water from the roof gutters for landscape irrigation. A fenced and protected side yard creates an ideal space for growing vegetables and establishing a high-desert garden. Fiber-optic internet provides excellent connectivity, while a shared well, septic system, and propane serve the property.
