The Boulder House is a forward-thinking green home and a rare creation by Hubbell & Hubbell, the acclaimed father-and-son team of the late celebrated artist James Hubbell and his son, architect Drew Hubbell. Recognized with architectural honors and featured in multiple publications, including The Los Angeles Times, this residence stands as both a work of art and a pioneering model of sustainable living. Blending artistry with innovation, the home features new ceramic tile floors, custom tile work, vaulted ceilings, and arched windows that flood the open layout with natural light. At its heart, the residence is literally built around a 14 -foot natural boulder, a dramatic centerpiece in the great room that cools and humidifies in summer and radiates warmth in winter. Above, a central tower fan enhances airflow, drawing heat up and out in warmer months and recirculating warmth in cooler seasons. Roof overhangs and arched arcades minimize solar gain while honoring California’s historic mission style. Super-insulated straw bale walls act like a thermos, keeping interiors comfortable year-round while exceeding California’s Title 24 standards by 41 percent. Recent upgrades include a newly re -plastered pool, freshly recoated exterior limestone, a new high-efficiency tankless water heater, new water softener, new well pump and renewed septic. Privately set against protected land and a wildlife sanctuary, the property offers unmatched seclusion, sweeping mountain views, and timeless architectural design.
