721 Marine Avenue This coastal Cape Cod-style home tucked into the Tree Section of Manhattan Beach is a truly special property that rarely comes to market. Built custom for the current owner, the residence reflects a timeless approach to coastal living—blending classic design with a relaxed indoor-outdoor lifestyle—all just moments from the Greenbelt, award-winning Grandview Elementary, and a quick bike ride to the beach. A striking entrance sets the tone, welcoming you into a light-filled living room anchored by a fireplace and two-story vaulted ceilings. Upon entry, sightlines extend through the home to the backyard water feature beyond. Brazilian cherry hardwood flooring and travertine stone run throughout, reinforcing a sense of craftsmanship and timeless design. Just beyond, the formal dining area and butler’s pantry set the stage for gatherings. A main-level office or ensuite bedroom completes the floor, offering flexibility for guests or work-from-home needs. The layout flows into the open-concept family room and kitchen—creating a warm, inviting heart of the home. A fireplace, breakfast nook, and direct backyard access enhance the flow. The kitchen features a large island, Sub-Zero refrigerator, stainless steel appliances, dual ovens, a breakfast bar, and a walk-in pantry. A built-in wet bar adds to the home’s entertaining appeal. Upstairs, three guest bedrooms offer comfort and scale, while the primary suite is positioned as a private retreat. Featuring custom built-ins, a spa-like bath, and a soaking tub overlooking the backyard, the space feels calm and private. A balcony off the suite is perfect for slow mornings or unwinding at sunset. The backyard is where the home truly stands apart. Rare for the Tree Section, the expansive 40x40 outdoor space is designed for entertaining and everyday living, featuring an outdoor kitchen, built-in bar, BBQ, firepit, and covered lounge beneath a trellis. Additional features include fresh paint throughout, a three-car garage with ample driveway parking, and 400 square feet of bonus space with a one-bedroom, one-bath au pair suite plus an additional flex room—ideal for a gym, media room, or creative studio. Located minutes from Manhattan Beach’s best restaurants and shopping, this home is a true blend of traditional elegance and effortless coastal living.
