Set on a full 50' x 150' lot in one of the most coveted pockets of Manhattan Beach, this extraordinary 4,900+ square foot residence blends European architectural grandeur with masterful craftsmanship at every turn. Renovated by a woodworking artist, the home boasts custom ceiling detailing, exquisite millwork, and abundant storage throughout. A soaring ceiling welcomes you into the formal living room, anchored by a grand European-style fireplace and marble flooring. A striking mezzanine framed by dramatic arches and pillars, finished in rosewood, overlooks the space below. The downstairs office features black walnut and engineered wood flooring. The showpiece kitchen, remodeled in 2019, features a full-slab quartzite island with a double waterfall edge — two complete slabs from Rock Mill — alongside black-and-white veined soapstone counters and a matching fireplace hearth. High-end appliances include a Sub-Zero French-door refrigerator, 48" Wolf double-oven range, Bosch dishwasher, and built-in microwave and beverage fridge. The adjoining family room impresses with custom bookshelves, a fireplace, and engineered hardwood flooring. The formal dining room dazzles with a decorative tin ceiling, bay window, and built-in mirrors and wall paneling. A jaw-dropping copper ceiling defines the game room, opening through double doors to the backyard. The downstairs bathroom, remodeled in 2023, features Carrera marble flooring and shower basin, Italian porcelain tile, luxury wallpaper by Sidney Paul & Co., and brass fixtures. Upstairs, a palatial primary suite impresses with a third fireplace, dentil ceilings, rosewood flooring, and an adjoining office with pocket French doors opening to a covered balcony. The resort-style bath includes a double shower, soaking tub, and two mirrored closets, one a full walk-in. A second en-suite bedroom offers intricate ceilings and rosewood flooring, while three more bedrooms and a full bathroom complete the level. Outside, a private backyard sanctuary boasts a pool with a 9-foot deep end and spa, both with newer heaters, mature cypress trees and ivy, a pergola, and turf lawn. Fine fixtures throughout are sourced from Lightopia, Signature Hardware, George's Plumbing, Pirch, Restoration Hardware, Battaglia's, and Rock Mill. The home also boasts a rare three-car, side-by-side garage with epoxy flooring, 28 solar panels, and two newer HVAC units. 1619 6th Street delivers true custom-estate quality for the buyer who expects nothing less.
