The dream of owning new construction in the coveted South Sand Section of Manhattan Beach is now a reality-and at a price point that is remarkably below today's estimated replacement cost, presenting an increasingly rare opportunity in one of Southern California's most desirable coastal communities. This elegant 3-bedroom, 3.5-bath residence features architectural plans by veteran architect Doug Leach, construction by 40-year local builder JRO Construction, and thoughtfully curated finish selections by esteemed Wendy Word Interiors.

Ideally positioned between Hermosa Beach and downtown Manhattan Beach, the home offers exceptional walkability to shops, dining, beaches, and everything that makes the Sand Section lifestyle so highly sought after. Seaside Heaven blends sophistication and functionality with a premier Thermador appliance package featuring a panel-ready French door refrigerator, a 46-inch 6-burner dual-oven range, Taj Mahal quartzite countertops, a soapstone wet bar with a fully integrated sink, natural slab surfaces throughout, rift-cut white oak cabinetry with custom architectural details, and bespoke stain-grade hemlock exterior wood siding. The private primary suite serves as an elegant retreat complete with a custom-designed closet. An innovative covered third-level patio with skylights and infrared heat creates a seamless indoor-outdoor living experience ideal for year-round coastal enjoyment. Offering refined design, top-tier finishes, exceptional value, and a coveted beachside location, Seaside Heaven delivers elevated Manhattan Beach living at its finest.
