Welcome to BLKHOUZ on 18th Street, where heritage begins. Our homes are built and designed with style, simplicity, and heart. This brand-new, expertly constructed Eastside Costa Mesa residence blends modern craftsmanship with timeless coastal charm. Featuring 5 bedrooms, 4.5 bathrooms, and 2,733 sq ft of thoughtfully designed living space — including a fully equipped ADU — this home is a true sanctuary just a short walk away from the vibrant shops and restaurants along 17th street and moments from Newport’s Back Bay and sparkling beaches. Alluring from the curb, the Hemlock clad siding, natural coastal California landscape and iron door draw you inside to soaring 18-foot cathedral ceilings wrapped in tongue-and-groove illuminated by skylights that flood the great room with natural light. Setting the stage for intimate dinners or lively gatherings, the dedicated dining area is bathed in sunlight accented by a modern industrial chandelier. The heart of the home, the chef’s kitchen, showcases warm natural white oak cabinetry, Viking appliances paneled in custom oak, handmade zellige tile backsplash and a striking slate island paired with Taj Mahal quartz countertops. A blend of warmth and modern elegance, the living room with custom white oak built-ins and striking fireplace wrapped in volcanic stone is perfect for relaxation or entertaining. Seamlessly blending indoor-outdoor living, the expansive sliding doors open to a cozy California room with tranquil views of the backyard. Retreat to the primary suite, where white oak cabinetry, Taj Mahal counters, zellige tile, and industrial brass fixtures create a spa-like escape. A skylight above the shower, ceramic soaking tub, dual walk-in closets, and curated lighting complete this luxurious haven. Each bathroom is uniquely designed with bespoke finishes — from checkered marble and terra cotta accents in the powder room to maple vanities, terrazzo flooring, and Rejuvenation lighting throughout. Ideal for guests, a home office or a private retreat, the ADU offers flexibility with a full kitchen, stainless steel appliances, quartz countertops, stylish bathroom, and a playful dark wainscoting main room.
