3134 Killarney Lane Offered for the first time in 48 years, this exceptional Halecrest residence presents a rare opportunity to own one of the neighborhood's most distinctive homes in one of Costa Mesa's most sought-after communities. Meticulously maintained and lovingly cared for over nearly five decades, this expansive single-level home offers over 2, 000 square feet, a size and layout rarely available in Halecrest. With 4 bedrooms and 2 bathrooms, the home seamlessly blends generous living spaces with everyday comfort. A thoughtful expansion in the early 1990s transformed the residence, adding a welcoming entry vestibule, an oversized primary suite retreat, and an expansive formal dining room designed for memorable gatherings. For buyers considering renovation or customization, this home presents an exceptional opportunity. The expanded footprint provides a significant head start, with substantial square footage and structural improvements already in place. In today's market-where construction costs, permitting, and timelines can be significant-the existing enlarged footprint may reduce the scope, complexity, and cost associated with future remodeling compared with starting from a more typical Halecrest floorplan. At the center of the home, the beautifully upgraded kitchen is both stylish and functional, featuring a large center island with built-in storage, abundant cabinetry, a spacious pantry with pull-out drawers, elegant granite countertops and backsplash, and a premium stainless steel appliance package. The lifestyle offered here is equally compelling. Ideally situated within Halecrest, residents enjoy walking access to Killybrooke Elementary School, proximity to Costa Mesa High School, and easy access to the cherished Halecrest Swim & Tennis Club. World-class shopping and dining at South Coast Plaza and the coastal lifestyle of Newport Beach and Huntington Beach are just minutes away. Designed to embrace California living, the backyard offers an expanded deck and sitting area-perfect for outdoor dining, entertaining, or quiet evenings at home-beautifully covered by a newer Alumawood insulated patio cover for year-round comfort. Homes of this caliber rarely become available in Halecrest-an extraordinary opportunity to own a truly special home in one of Costa Mesa's most cherished neighborhoods.
