Set on a quiet, tree-lined cul-de-sac on the 300 block of Eastside Costa Mesa, this fully reimagined 5-bedroom, 4-bathroom residence delivers the craftsmanship of a brand-new custom build. The 2,863 square foot home sits on a 7,910 square foot lot and arrives turnkey. A marble penny-tile foyer opens to wide-plank European white oak floors and a flowing main-level plan. The formal living room is anchored by a marble-surround fireplace; the dining area accommodates an inviting entertaining space. The chef's kitchen features white oak cabinetry, Taj Mahal quartzite counters, a Black Diamond quartzite waterfall island, professional gas range, double ovens, integrated wine refrigerator, and premium Thermador appliance suite. A vaulted great room with timber beams opens through new bi-fold doors to the covered patio and backyard. Upstairs, the primary suite features a built-out white oak dressing room and a spa-caliber experience in book-matched marble and Calacatta Dolomiti. Three additional bedrooms share a designer hall bath; a main-level guest bedroom and bath complete the plan. The detached 2-car garage offers workshop, gym, or studio flexibility, with ADU optionality. Comprehensively upgraded: new roof, HVAC, water heater, electrical panel, windows, fixtures, smart-home, and laundry. Minutes from Westcliff, East 17th Street, the Upper Back Bay, top-rated Newport-Mesa schools, and Coastal Orange County beaches.
