Desirably located on a welcoming street in Eastside Costa Mesa, 366 Esther Street radiates the warmth and ease of coastal living. Within the Newport-Mesa school district—and just a short bike ride to the beach or a leisurely stroll to the shops and dining along 17th Street—the home offers a lifestyle as enviable as its design. Fully renovated, rebuilt, and expanded in 2022 with approximately 30% of the original 2x4 studs remaining – everything else being new – what was once a 1,200-square-foot cottage is now a 2,434-square-foot residence of thoughtfully curated living space, complemented by an additional ~200 square feet of flexible space connected to the detached garage, ideal for a home office, creative studio, or gym. A unique gated entrance sets the stage, showcasing a custom cedar-wood façade with a glass Dutch door, while a playful putting green and eco-friendly landscaping complement the modern exterior color palette, creating an exterior as inviting as the interior. Inside, the open great room balances modern luxury with timeless warmth. Striking marble countertops, wood and tile flooring, and custom cedar accent paneling set the tone, while a cohesive color scheme flows seamlessly from room to room. The kitchen—anchored by a dramatic marble waterfall island, bold custom black cabinetry, and brass fixtures—functions as both a culinary workspace and a welcoming gathering spot. The primary suite is a private retreat, with double French doors opening to the outdoor living area and spa, blending indoor comfort with serene outdoor living. The spa-inspired ensuite continues the elevated aesthetic, with dual vanities, designer finishes, and a freestanding soaking tub that transforms daily routines into indulgent moments. A generous walk-in closet completes the space with abundant storage and organization. Additional living areas include three bedrooms plus the flexible extension of the detached garage, offering versatility for a variety of lifestyle needs. With thoughtful updates, harmonized finishes, and a natural, 366 Esther Street embodies the perfect blend of modern design and coastal charm—an inviting sanctuary where every detail feels purposeful and every moment at home feels effortlessly serene.
