Welcome to 76 4th Street North, a rare prime residential homesite perfectly positioned north of Central Avenue on a mahogany tree lined street in the heart of Old Naples most walkable and desirable enclave. Located within an X500 flood zone, the best rating for lowest flood risk, this cleared lot offers an exceptional foundation for a custom coastal residence. From this address, enjoy a true walking lifestyle just steps from the acclaimed shops, galleries, and restaurants of 5th Avenue South, the white sand beaches of the Gulf of Mexico, the farmers' market, and Old Naples' year round cultural events. Morning beach walks and evening sunsets can easily become part of everyday life. The lot benefits from rare rear alley access, allowing garage entry from the alley and a clean unobstructed front elevation. This highly desirable feature enhances curb appeal and provides architectural flexibility, something increasingly difficult to find in Old Naples. Buildability is a key strength of this property. The lot supports a residence of approximately 4,000 square feet including a three car garage and private pool, offering the scale and flexibility today's luxury homeowners expect. Architectural sketches by MHK Architecture are available, providing a head start with a thoughtfully designed plan featuring three bedrooms plus a study, an upstairs loft, 3.5 bathrooms, open concept living, and seamless indoor outdoor flow. The property is centrally located within the core Old Naples envelope, where buildable and well located lots are exceptionally scarce. Of the limited number of remaining Old Naples parcels, very few combine walkability, alley access, flood zone security, and meaningful build potential. From a value standpoint, this is a rare opportunity to control design and cost basis in a neighborhood where new construction homes by premier builders are in high demand. This makes the lot especially compelling for buyers who understand construction economics and long term value in Old Naples. This offering is well suited for serious and informed buyers who recognize that there are very few comparable opportunities remaining. 76 4th Street North represents a rare chance to create a custom residence in one of Naples' most prestigious and enduring neighborhoods, where lifestyle, location, and long term value converge. A must see!
