865 W I Street Originally built in 1942 as a seaside vacation cottage welcoming visitors arriving by train and ferry to Benicia, this extraordinary property has been thoughtfully transformed into a flexible coastal retreat blending history, craftsmanship, privacy, and modern functionality. Extensively renovated and expanded beginning in 2004 with the collaboration of respected local contractor Laverty Construction and architect Steve McKee, the original residence was raised and reimagined to create multiple living possibilities for today's evolving lifestyles.  Currently configured upstairs is a two bedroom, two bath main residence with a spiral staircase leading up to private third floor lookout sanctuary with peaks of the Carquinez Strait, and downstairs a large studio-style space with full bath, kitchenette, and office area; previously used for exercise, dance, and therapy. The lower front of property features a comfortable permitted one (or two) bedroom apartment with attached garage, and private entrance. The flexible layout offers rare opportunities for multi-generational living, ADU, income potential, creative workspace, or conversion back to a larger single-family residence.  Located just one home from 9th Street Park, beach, and boat launchand only a short stroll to a beloved neighborhood restaurantthe setting captures the relaxed waterfront character that defines this treasured area of Benicia.  Major infrastructure improvements completed in 2006 include: complete foundation and plumbing, electrical, HVAC, windows, sewer, irrigation, roof, gutters, and driveways. Custom exterior details including handcrafted metal railings and IPA decking. Inside, repurposed redwood trim and doors from an 1890s farmhouse complement restored Douglas fir flooring, while cork, slate, tile, and commercial-grade carpeting add warmth and durability throughout.

Subtle nautical touches, include repurposed functional portholes, and quietly honor the property's coastal roots.  Completing the offering are both a one-car garage and oversized two-car garage with skylight opening; along with gated alley access providing flexible off-street parking (could accommodate RV) and secure enclosure of the rear and side yards. This exceptional residence speaks architectural character, everyday ease, and the best of California living.
