Exquisite 5-Bedroom, 3-Bathroom La Costa Retreat with Two Permitted separate living Spaces, each with 1 bedroom, bathroom, and kitchens. Nestled in the heart of La Costa—one of Carlsbad's premier neighborhoods—this exceptional residence sits on a generous large lot, offering rare privacy, beautifully landscaped grounds, and remarkable versatility for multi-generational living, extended family, guests, home offices, or creative studios. The elegantly updated main home features 5 bedrooms and 3 bathrooms, graced with new hardwood flooring throughout, a gourmet kitchen appointed with premium stainless steel appliances, custom cabinetry, and French doors that open seamlessly to an expansive entertainer’s patio—perfect for sophisticated indoor-outdoor gatherings.

The expansive master suite offers a serene sanctuary with generous proportions, abundant natural light, and direct access to a large private patio—an intimate retreat for morning coffee or evening relaxation. This home is designed for effortless entertaining, with seamless flow from indoor spaces to the sprawling outdoor patios and grounds. Located just moments from La Costa’s finest restaurants, top-rated schools, pristine beaches, and amazing amenities.
