Located just four blocks from the sand and four blocks from the vibrant shops and dining of Main Street, this exceptional residence offers one of the most desirable settings in Huntington Beach-walkable, yet quietly tucked among predominantly single-family homes. 509 8th Street is a fully reimagined coastal retreat, thoughtfully rebuilt down to the studs by its interior designer owner. Every detail has been curated with a refined eye, blending timeless design with elevated craftsmanship. The home is uniquely configured with four bedrooms-an uncommon offering in Downtown. Inside, bespoke finishes define the space-from Amish-crafted Mullett cabinetry and custom millwork to a vintage Malm fireplace and a striking staircase built from 100-year-old Oregon barn wood. The chef's kitchen features a Sub-Zero refrigerator, Viking range, Cove dishwasher, marble island, and designer fixtures throughout. Natural light pours in through expansive glass, including a dramatic garage door-style opening that creates seamless indoor-outdoor living. Multiple outdoor spaces-including two main-level patios, two rooftop decks, and a private turf dog run-offer versatility for entertaining and everyday living. Recent upgrades include new plumbing, electrical, HVAC, smooth-coat stucco, and premium finishes throughout. Rarely does a home of this caliber, design pedigree, and location come to market. 509 8th Street is a standout opportunity to own one of Downtown Huntington Beach's most distinctive properties.
