Developed by the seller's father in the mid-1960s, 205-207 Holly Street is part of a unique collection of neighboring, similarly designed duplexes-each situated on its own parcel, yet together creating an intimate, almost compound-like feel. Nestled in Harry Floyd Terrace of North Vallejo, within the Flosden Acres subdivision, this unusually spacious duplex has a distinctive presence and plenty of potential. Like identical twins, both units feature two generously sized bedrooms and one bathroom, along with impressively large living rooms, substantial dining areas, spacious kitchens, and attached garages. Each unit also enjoys a separate, roomy laundry/utility area with convenient interior access. The oversized floor plans are only part of the story. Set on an expansive approximately quarter-acre lot, the property offers an impressive amount of outdoor space that beautifully complements the scale of the duplex and creates possibilities for its next owner to explore. Built with size, function, and a sense of permanence rarely found in today's construction, 205-207 Holly Street is ready for renewed love, vision, and care. Whether considered for investment, multigenerational living, or an owner-occupant seeking additional income potential, this distinctive North Vallejo duplex offers space, character, and opportunity-and it is priced to invite its next chapter.
