Welcome to Seaside Heaven, a newly constructed South Sand Section townhome offering a refined blend of modern luxury and relaxed coastal living. The opportunity to own new construction in Manhattan Beach’s coveted South Sand Section is increasingly rare—particularly at a price point remarkably below today’s estimated replacement cost.
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. Crafted by one of Manhattan Beach’s most seasoned builders, no detail has been overlooked. Every finish, fixture, and architectural element has been intentionally considered to deliver exceptional quality, functionality, and timeless coastal appeal.
Ideally positioned in a true “Goldilocks” Sand Section location—perfectly situated between Hermosa Beach and downtown Manhattan Beach—Seaside Heaven puts you close to everything while maintaining a relaxed residential feel. Enjoy exceptional walkability to the beach, shops, dining, cafés, and the best of both downtown districts, creating a location that feels just right for the quintessential Manhattan Beach lifestyle.
Seaside Heaven pairs sophisticated design with everyday functionality, featuring a premier Thermador appliance package with a panel-ready French door refrigerator and 46-inch 6-burner dual-oven range, Taj Mahal quartzite countertops, a soapstone wet bar with integrated sink, natural slab surfaces throughout, rift-cut white oak cabinetry with custom architectural detailing, and bespoke stain-grade hemlock exterior wood siding.
The private primary suite provides an elegant retreat complete with a custom-designed closet, while an innovative covered third-level patio with skylights and infrared heat creates a seamless indoor-outdoor living experience designed for year-round coastal enjoyment.
