Welcome to #1 Lower Dover Rd, a stunning architectural residence. This thoughtfully crafted 4 bedroom 3 1/2 bath original-owner home is the visionary work of renowned architect Igor Sazevich, offering an exceptional blend of refined materials, modern comforts and West Marin tranquility. Step inside and experience craftsmanship at every turn from solid cherrywood interior doors and custom kitchen cabinetry to granite countertops and concrete heated floors. The main living/dining area with vaulted ceilings and striking views of Black Mountain and the Tomales estuary create an inviting gathering space. The primary bedroom on the main floor is graced by one of the two fireplaces in the home, 2 walk-in closets, full bath with dual sinks, a bidet and shower with floor to ceiling windows. The lower-level features 3 bedrooms, 2 full baths, a generous laundry area with sink and abundant storage cabinets as well as access to exterior storage and a hot tub. One generously sized bedroom provided an art studio/workspace for the current owner. The home includes foundational steel pillars, a steel roof, stucco exterior and covered gutters. Gracious irrigated landscaping encircles the home. This is a rare opportunity to own a truly exceptional property in one of Marin's most coveted locations.
