Newly built and thoughtfully designed, 1721 2nd Street blends contemporary architecture with timeless finishes, exceptional scale, and seamless indoor-outdoor living in the heart of Manhattan Beach. Entering through the oversized front door, a double-vaulted entry creates a striking first impression, with sightlines extending through the open-concept main level to the rear yard. Defined by 10-foot ceilings, expansive proportions, and walls of glass framed by oversized Marvin windows, the home is filled with natural light and a strong sense of connection throughout. A formal dining room offers an elegant setting for large-scale entertaining, flowing into the kitchen and main living areas. At the center of the home, the kitchen is anchored by a 10-foot Perla Venata quartzite island and features custom natural oak cabinetry and a full suite of premium appliances, including a 48-inch Wolf range, Sub-Zero refrigeration, full-height wine storage, and dual dishwashers. A secondary dining area opens directly to the backyard through oversized LaCantina doors. The main living room features a statement fireplace, custom built-ins, and seamless access to the outdoors. A 400-square-foot covered outdoor living room with fireplace, along with a built-in BBQ kitchen, extends the home's footprint and enhances year-round livability. The main level also includes a versatile ensuite bedroom, powder room, and custom mudroom with direct access to the oversized three-car garage. Upstairs, three secondary bedrooms each offer ensuite baths and ample closet space. An oversized loft provides flexible living space, while the primary suite serves as a private retreat with a fireplace, terrace, and spa-like bath featuring a soaking tub, dual vanities, and a custom walk-in closet. Wide-plank white oak flooring, custom oak doors, curated stonework, and Perla Venata quartzite surfaces define the interiors, complemented by Brazo and Delta fixtures. A fully integrated smart home system with audio, lighting, and security, along with solar panels and fire sprinklers, enhances modern living. Defined by its open-concept layout and effortless indoor-outdoor connection, 1721 2nd Street offers a rare blend of modern sophistication and elevated coastal living in one of Manhattan Beach's most sought-after locations.
