865 W I Street – A One-of-a-Kind Coastal Masterpiece – Originally built in 1942 as a seaside vacation cottage, 865 W I Street has been transformed into an extraordinary coastal compound unlike any other home in Benicia. Beginning in 2004, a creative master craftsman, working with a highly regarded local design and construction team, extensively renovated and expanded the property, creating a remarkable blend of craftsmanship, artistry and nautical character. Everywhere you look, there is something unexpected: original porthole windows, custom woodwork, repurposed redwood trim and doors salvaged from an 1890s farmhouse, beautifully restored Douglas Fir floors, and countless distinctive handcrafted details. The nautical influence is woven into the architecture itself, creating the feeling of a private coastal retreat. And then there is the crow’s nestclimb to the top and take in the water view. It is an unforgettable feature that perfectly captures the spirit of this remarkable home. The extensive renovation included major updates to plumbing, electrical, HVAC, sewer and irrigation systems, as well as the roof, gutters, driveways and custom exterior elements. Equally remarkable is the property’s versatility. The current configuration includes a 2-bedroom, 2-bath main residence, a private studio/living area with full bath and office/bedroom, plus a permitted 1-bedroom, 1-bath apartment with dedicated garage. Use it as a spacious single-family home with up to 5 bedrooms and 4 baths, create a multigenerational residence with privacy for everyone, or enjoy the current configuration with income-producing space and a creative studio. A two-car garage with gated alley access even provides room for the sailboat. Mature trees and lush landscaping create surprising privacy, while 9th Street Park, the beach and boat launch are just steps away and downtown Benicia’s restaurants, galleries and waterfront are a short bike ride away. You simply won’t find another home with this extraordinary combination of unique architecture, imaginative craftsmanship, nautical character and truly one-of-a-kind custom details.
