Ideally situated on one of the most coveted blocks in lower Eastside Costa Mesa, 332 Walnut Street presents a truly rare opportunity. Lovingly owned and cared for by the same family for decades, the property offers exceptional flexibility with a permitted addition that creates a separate living space while preserving the ability to reconnect the spaces into one cohesive residence. The main home features two bedrooms and two bathrooms, along with a spacious second living area currently configured as an additional one-bedroom, one-bathroom suite. Upon entering, you are immediately greeted by a wonderful sense of space and volume, highlighted by vaulted ceilings and abundant natural light in the great room. The adjacent open kitchen offers ample counter space, counter seating, and a butcher-block surface ideal for food preparation. A formal dining area, complete with an inviting brick fireplace, provides a warm setting for entertaining and everyday living. Off the great room, a hallway leads to a full bathroom, a generously sized secondary bedroom with views of the front courtyard, and the primary bedroom with its en-suite bathroom. Accessible from the front courtyard through its own private entrance, the additional living space offers a similar great-room layout with an adjacent open kitchen and bar-top seating. A spacious full bathroom and private bedroom complete the space, which could easily be opened back up to the main home. Whether used for extended family, guests, a home office, or additional living quarters, the flexibility makes this a particularly compelling feature of the property. Outside, the well-manicured front lawn and mature plantings create a welcoming first impression, while the private rear entertaining area provides an ideal setting for relaxing or gathering with friends and family. A garage with direct access to the home adds everyday convenience. Perfect for a buyer looking to add value and personalize a home in one of Costa Mesa's most desirable neighborhoods, 332 Walnut Street is ideally positioned just moments from award-winning schools and parks, the shops and restaurants of 17th Street, the Back Bay Nature Reserve, and the famed beaches of the Newport Peninsula. With its exceptional location, flexible floor plan, and tremendous potential, 332 Walnut Street is a rare opportunity to make a home in lower Eastside Costa Mesa.
