Property Description

An open-concept contemporary design and panoramic views work in perfect harmony at this 4,000+ SF home, situated on the waterfront of exclusive Promontory Bay. Recently renovated, this four-bedroom home—featuring one bedroom on the lower level and one currently used as a gym—delivers chic, turn-key accommodations punctuated by unique architectural elements, including a sunken living room, floating staircase, and walls of glass that open for optimal indoor-outdoor living. A clean motif is enjoyed throughout the residence, featuring glossy white cabinets, floating vanities, and a neutral color palette. A wet bar in the main living area and a kitchen with an oversized island foster effortless entertaining, while quartz countertops, abundant storage, and premium Viking appliances, including a wine refrigerator, ensure culinary mastery. A stylish patio spans the width of the home, offering a dining and seating area with a fire pit, as well as access to the home's private dock, which currently holds a 53-foot center-console, 29-foot Zodiac, and 23-foot Duffy boat. An ascent to the second level reveals the primary suite, a gym (which can serve as an optional fourth bedroom), a laundry room, and the third bedroom await, with the latter featuring an en-suite bath and French doors opening to a rooftop deck with a fireplace, refrigerator, and views of Balboa Island. The primary suite elevates everyday living with custom built-ins, an infrared sauna, a spa bath with steam shower, a lavish retreat with a media center and fireplace, and a private balcony overlooking the private beach exclusive to Promontory Point and Promontory Bay residents. A three-car garage completes this pristine waterfront estate.
