About This Property

Few Bay Area homes offer this combination of expansive lagoon frontage, a heated pool, and an oversized private dock. Lagoon views unfold from nearly every room of this estimated 3,300 sq. ft. waterfront residence. Positioned at the end of a quiet cul-de-sac, the home offers 5 bedrooms, 3 full baths, 2 half baths, a new roof, and a refreshed modern interior.  Start the morning with a poolside workout or yoga, launch a paddleboard or kayak directly from your dock, take an afternoon swim, or gather with family and friends for outdoor dining. With room for backyard games, entertaining, exercise, and recreation, this expansive waterside setting makes an active outdoor lifestyle part of the daily routine.  The versatile two-story floor plan offers excellent separation. A private first-floor bedroom with pool views and adjoining full bath is ideal for guests or multigenerational living. The formal living room features a fireplace and expansive windows. The refreshed eat-in kitchen offers new quartz countertops, stainless steel appliances, a breakfast bar, and opens to the family room. A formal dining room and powder room complete the main living areas.  The primary suite features a fireplace, dual vanity areas, dual closets, and a gorgeous new shower. Two additional lagoon-facing bedrooms share a stylish Jack-and-Jill bath with a view shower.  Spanning the width of the home, the fifth bedroom showcases soaring vaulted ceilings, panoramic lagoon views, a view balcony, wet bar, and half bath with potential to convert to a full bath. Its impressive scale offers flexibility as an executive office, media or game room, guest suite, or apartment-style retreat.  Beyond your doorstep is the Alameda lifestyle: highly regarded schools, beaches, parks and shoreline trails, plus the shops, restaurants and neighborhood energy of Park Street and Webster Street. Explore Alameda Point and Spirit Alley for waterfront recreation, open spaces, wineries and breweries. With Oakland International Airport nearby, ferry service to San Francisco, and convenient connections throughout the Bay Area, Alameda offers a distinctive island community with the city within reach.
