45 Bella Vista Avenue

A rare Mid-Century modern home of genuine architectural pedigree, 45 Bella Vista Avenue was designed by Charles Warren Callister one of the defining voices of mid-century California architecture and the preeminent practitioner of the Second Bay Area Tradition and has now undergone a meticulous, design-forward transformation by Moso Design Inc. that stands as one of the most thoughtfully executed renovations on Belvedere Island in recent memory. The scope of the work is comprehensive: four bedrooms, three bathrooms, an entirely new gourmet kitchen, all new baths, new plumbing and electrical throughout, new walls, new doors, and more a ground-up reimagining of every system and surface in the home. Yet what makes this renovation genuinely extraordinary is not what was changed, but what was preserved. Moso Design's approach remains deeply faithful to Callister's original vision. The clean structural lines, the warm natural materials, the Japanese-inspired mahogany trim, the floor-to-ceiling windows that dissolve the boundary between interior and landscape, and the seamless integration with the leeward Belvedere setting that made Callister's homes so enduring. The architecture has been honored, not overwritten. The result is a home that offers something the market rarely produces, the soul of a landmark mid-century design and the full refinements of contemporary living in the same address, at the same moment. For the discerning buyer who understands that heritage and modernity are not competing values but complementary ones, 45 Bella Vista Avenue is without parallel on the island.
