House Description

Introducing a newly constructed 2026 Honomobo HO5 in St. Helena a bold, sophisticated residence designed to celebrate light, landscape, and effortless Wine Country living. More than 60 feet of floor-to-ceiling glass stretches across the home, drawing the surrounding hills, mature trees, and colorful evening skies into nearly every room. Expansive accordion doors dissolve the boundary between the interior and the custom wraparound deck, creating an extraordinary environment for entertaining, outdoor dining, or simply watching the sun settle over the valley. Inside, approximately 1,600 square feet of thoughtfully designed living space includes three bedrooms, two and one half baths, engineered hardwood flooring, modern appliances, contemporary electronics, and clean architectural finishes. Energy-efficient heat-pump heating and air conditioning and a heat-pump water heater bring next-generation comfort to the home. A custom-built two-car garage, generous additional parking, sculptural water features, natural stonework, and warm wood and steel accents complete a property unlike anything else currently offered in St. Helena.
