Rarely available, this historic Spanish Revival duplex at 140 & 140 1/2 Avenida Miramar offers Mills Act designation and timeless coastal living in the heart of San Clemente. Originally built in 1927 and rebuilt from the foundation up, the home blends preserved architectural character with extensive renovation and modern functionality. Thoughtfully reimagined by architect Michael Luna, the property underwent a comprehensive remodel designed to honor its historic integrity while enhancing everyday livability. Architectural details include authentic lime-wash stucco, restored original windows, floors, and woodwork, and preserved lath-and-plaster construction, complemented by updated electrical, all-new plumbing, and modern infrastructure. The flexible multi-unit layout offers possibilities for extended living, guests, or income potential. Interior spaces are warm and light-filled, featuring custom architectural detailing, 100+ year-old bathroom mirrors, hand-selected Talavera tiles, a cast iron kitchen sink with structural reinforcement, and a refined blend of historic craftsmanship and modern comfort. Outdoor spaces include a private courtyard and peek-a-boo ocean views from the upper level. Additional features include a natural gas BBQ hookup, crawl space access on both structures, and foundational reconstruction completed during the rebuild. Located near beaches, coastal trails, and downtown San Clemente, with walkable access to Del Mar dining, shopping, and local cafes, this is a rare opportunity to own a thoughtfully restored historic property offering Mills Act tax savings and timeless coastal character.
