Batter Kay Associates Architects, an award-winning modern architecture firm at 2195 San Dieguito Dr, Suite 4, Del Mar, CA 92014, was founded in 1975 by Harvard Graduate School of Design alumni Janice Kay and Michael Batter. The husband-and-wife team arrived in San Diego inspired by the rigorous elegance of the Bauhaus movement and the timeless forms of Le Corbusier, Josep Lluis Sert, Charles Gwathmey, and The Architects Collaborative — and they have maintained that modernist discipline for half a century. Drive through the hills of Del Mar and La Jolla and you are likely to spot their work: a Batter Kay house has become synonymous with a white-on-white palette, curvaceous sculptural forms, and an abundance of natural light. Janice Kay Batter is a Del Mar native whose office overlooks the San Dieguito Lagoon, and the firm has completed more than 200 projects, primarily in the San Diego area. The practice designs custom residential, educational, retail, office, and industrial buildings across the United States. Ranch & Coast Magazine profiled the firm's 50-year legacy, highlighting signature projects like the Mountain Top House with its 90-foot interior sightline and the Dorne House in La Jolla. Many Del Mar homes on small lots incorporate basements to maximize square footage — a challenge Batter Kay navigates by sculpting angled forms that capture ocean views without obstructing neighbors' sightlines. The office is open weekdays from 8 AM to 4 PM with wheelchair accessible entrance and parking. Just down San Dieguito Drive, Jensvold Associates Architects operates on Carmel Valley Road, offering a complementary nature-based design approach. When a Batter Kay design moves into construction, Sheiner Construction is among the Del Mar remodeling contractors experienced with high-end custom residential builds.
