29 Lower Alcatraz Place presents a rare opportunity to build a custom residence in one of Mill Valley's most coveted downtown locations. Set on an expansive approximately 17,001 square foot street-to-street cul-de-sac lot, this is one of the last remaining buildable parcels just moments from the heart of downtown Mill Valley. Conceptual architectural plans envision a beautifully designed approximately 2,700 square foot home, offering the chance to bring your vision to life in an exceptional setting. Utilities are available at the street, helping streamline the path toward development. The location is truly special, tucked away in a peaceful setting while just blocks from downtown Mill Valley's renowned restaurants, boutiques, cafes, parks, and vibrant community atmosphere. Opportunities to create a brand-new home in such a prime in-town location are increasingly rare.
