Gracefully positioned on a sprawling parcel at the end of one of Eastside Costa Mesa's most desirable cul-de-sacs, 330 Colleen Place presents a rare opportunity to own a beautifully executed Craftsman home complete with a separate studio above the garage. From the moment you arrive, the home's authentic architectural character is unmistakable, with meticulous attention to detail evident both outside and throughout the interior. Inside, a welcoming living room with a wood-burning fireplace flows seamlessly into an adjacent dining area, creating a warm and inviting space ideal for everyday living and entertaining. The main residence offers three bedrooms and two bathrooms, complemented by a spacious studio with its own bathroom above the garage-perfect for a home office, guest suite, gym, or creative space. Thoughtfully designed, the floor plan features wood flooring throughout most living areas, dual-pane double-hung windows, and a separate den for added flexibility. The kitchen is conveniently located adjacent to a casual dining nook and is outfitted with newer custom cabinetry, stainless steel appliances, and generous counter space and storage. The expanded primary suite serves as a private retreat, featuring direct access to the outdoors and a spa-inspired bathroom complete with a walk-in closet and oversized shower. Equally impressive are the grounds, where mature specimen trees, a tranquil stream, and a pond create a serene, secluded atmosphere in the rear entertaining area. Additional highlights include a roof installed in 2025, new interior and exterior paint, solar system, citrus trees, abundant off-street parking, and a workshop space within the garage. Ideally situated just moments from award-winning schools, the shops and dining of 17th Street, and the renowned beaches of the Newport Peninsula, this exceptional Craftsman residence is a rare offering and a true labor of love in a highly coveted location.
