About 209 Diamond Avenue
Enter through a graceful white arbor and gate, where winding brick pathways meander through a romantic garden sanctuary filled with lush landscaping, timeless coastal charm, and nostalgia for days gone by. Beneath a magnificent shade tree, dappled sunlight falls across a charming garden swing. Elegant brickwork, curated greenery, and intimate seating invite you to linger beside a striking brick fireplace, perfect for quiet mornings, sunset gatherings, and evenings beneath the stars. A built-in barbecue completes the setting for summer dinners and outdoor entertaining, all on one of Balboa Island’s most desirable streets. Voted one of Balboa Island’s loveliest front yards, this extraordinary coastal cottage is a rare expression of charm, character, and timeless design. Beyond its inviting façade lies a completely reimagined three-bedroom, three-bathroom residence that pairs the soul of a classic cottage with sophisticated modern living. Vaulted ceilings and a warm fireplace create an inviting atmosphere in the beautifully appointed living room, where refined finishes meet a relaxed coastal sensibility. The thoughtfully designed kitchen features premium appliances, a walk-in pantry, and a dedicated coffee bar. A separate dining area offers a welcoming setting for gatherings with family and friends. Upstairs, the primary suite features its own custom fireplace, joined by two additional bedrooms and beautifully appointed bathrooms. A freestanding soaking tub and separate walk-in shower add a spa-like touch, while an expansive private deck offers another place to unwind in the coastal air. A private office or den and sauna add versatility and indulgence, while a standing-seam metal roof completes the home with distinctive architectural character. Exceptional craftsmanship and thoughtful details create a residence that feels timeless yet suited to modern island living. Beyond the garden gates, the best of Balboa Island unfolds at an unhurried pace. Wander the waterfront boardwalk, discover beloved boutiques and cafés, or enjoy an evening stroll along the harbor. Distinctive in every detail and unforgettable in its setting, this is more than a beautifully reimagined cottage. It is a place to gather, celebrate, and create generations of cherished memories, from sun-filled summers to holiday traditions and year-round island living.
