Property Description
A rare opportunity to own a piece of Santa Monica architectural history in the highly coveted North of Montana neighborhood. Known as the Walter Boswell Residence, this distinguished Spanish Colonial Revival home was designed and built in 1925 by noted architect John Byers, recognized as one of Santa Monica's foremost architects of the early 20th century. Offered for sale for the first time in more than 60 years, the residence features 5 bedrooms and 3 bathrooms across approximately 2,713 square feet of living space on a 7,212-square-foot lot. Rich in history, character, and architectural pedigree, the property presents an exceptional opportunity to preserve, restore, or thoughtfully reimagine an important Santa Monica residence. Ideally situated just moments from the boutiques, cafes, restaurants, and neighborhood conveniences of Montana Avenue, as well as nearby schools, Palisades Park, the scenic coastal bluffs, Santa Monica Beach, and the Pacific Ocean. With its premier North of Montana setting, historic provenance, and enduring Spanish Colonial Revival architecture, 624 Alta Avenue represents a truly special offering in one of Santa Monica's most sought-after residential neighborhoods.
