Set on an oversized lot-and-a-half in Manhattan Beachs historic Gas Lamp District, just five blocks from the beach, 522 Marine Avenue, affectionately known as Marine Manor, is an exceptional residence that seamlessly blends thoughtful renovations, distinctive architectural details, and modern functionality. Offering unexpected scale and versatility, the home features living spaces with easy indoor-outdoor flow.

Below, a dramatic great room with 11-ft ceilings features a floor-to-ceiling built-in and rolling ladder, a full bar with sink, refrigerator and dishwasher, and extensive storage, including approx 600 sqft of crawl-space storage.
